This case involves the validity of an ambiguous devise of real estate in a will. We hold that the trial court erred in ruling that the devise was valid and in granting summary judgment to defendant accordingly.

The testator, Aaron William Rowe, owned a large farm of about 160 acres, where he lived with his second wife, Lucille Jones Rowe. His will contained the following provision:
I will, devise and bequeath to my wife, Lucille Jones Rowe, the homeplace occupied by us at the time of my death, together with thirty (30) acres of real estate immediately surrounding the homeplace, to be hers in fee simple, absolutely and forever.
A general residuary clause placed the remainder of the testator’s property, both real and personal, in trust for Lucille Rowe and the testator’s seven children by his first marriage, with Lucille Rowe as trustee. The trust property was to be divided equally among the beneficiaries.
The thirty-acre devise was not surveyed or fenced off before the testator’s death. After his death, Lucille Rowe, in her capacity as executrix, had the thirty-acre tract surveyed and deeded to herself individually.
*719Plaintiffs, three of the testator’s children, his first wife, Maxine Rowe, as guardian ad litem for the minor children, and a guardian ad litem for the children’s unborn issue, filed the present action seeking a construction of the will and a declaration that the attempted thirty-acre devise failed for vagueness. Defendant, Lucille Rowe, individually and in her capacity as executrix (hereinafter referred to simply as defendant), filed a lengthy answer contending that the will was at most latently ambiguous, or in the alternative, counterclaimed that the court should impose a constructive trust on the land. She then moved for partial summary judgment on the construction issue, supported by numerous affidavits describing the testator’s expressions of intent before his death. Plaintiffs moved to dismiss the counterclaim and for summary judgment. The trial court denied the motion to dismiss and granted summary judgment to defendant on her motion, ruling that Lucille Rowe individually held title to the thirty-acre tract as set forth in the survey made after the testator’s death. From this order, plaintiffs appeal.

Defendant moved to dismiss the appeal for plaintiffs’ failure to file it within the 150-day limit set by the Rules of Appellate Procedure. 4A N.C. Gen. Stat. App. I (2A), N.C. R. App. P. 12(a) (Supp. 1983). Although the trial court apparently announced its judgment at a hearing in November 1982, it did not render a signed judgment until February 1983, at which time it also signed and filed plaintiffs’ appeal entries. Plaintiffs filed the record in this Court in July 1983. The 150-day limit depends on the giving of notice of appeal. It is well established that the time limit for giving notice starts to run when the trial judge announces his decision in open court, unless the court provides for judgment to be effective on signing. The date of the written order does not control. N.C. Gen. Stat. § 1-279 (1983); N.C. Gen. Stat. § 1A-1, Rule 58 (1983); 4A N.C. Gen. Stat. App. I (2A), N.C. R. App. P. 3 (Supp. 1983); In re Moore, 306 N.C. 394, 293 S.E. 2d 127 (1982), appeal dismissed, 459 U.S. 1139, 74 L.Ed. 2d 987, 103 S.Ct. 776 (1983). Plaintiff appellants made no motion to extend the time for filing the appeal, and thus it is subject to dismissal. Nevertheless, in our discretion, we treat the purported appeal as an application for writ of certiorari, allow same, and proceed to consider the *720merits. N.C. Gen. Stat. § 7A-32(c) (1981); 4A N.C. Gen. Stat. App. I (2A); N.C. R. App. P. 21 (Supp. 1983).
III
Plaintiffs first challenge the form of the judgment. We find the summary judgment order sufficiently clear to dispose of this assignment. The trial court ruled that the will was, at worst, latently ambiguous, and that plaintiffs forecast no extrinsic evidence, which would raise a genuine issue of fact as to which thirty acres testator intended to devise to defendant. Plaintiffs raised no other issues in their Complaint, except whether defendant was appointed as trustee under the will. The will itself clearly and definitively answers that issue in defendant’s favor. Once the trial court granted summary judgment on the construction issue, defendant’s counterclaim for the declaration of a constructive trust became moot. Since the trial court accepted defendant’s evidence that testator intended to devise a certain thirty acres, and since that thirty acres had already been deeded to Lucille Rowe and no longer abutted any other property of the estate, it appears that no further judicial proceedings were necessary to establish the boundaries. Accordingly, the summary judgment, although nominally partial, effectively resolved all issues. Since the summary judgment against plaintiffs resolved the case, the trial court could properly tax costs following the judgment. N.C. Gen. Stat. § 6-21 (1981).
IV
As a result, the only question we need decide is the propriety of the grant of summary judgment on the construction issue.
In construing a will, the intent of the testator is the “polar star” which guides the courts. Adcock v. Perry, 305 N.C. 625, 290 S.E. 2d 608 (1982). The testator unequivocally intended to give Lucille Rowe thirty acres of land, and we should not lightly disregard such clearly expressed wishes.
However, we may perform our duty to give effect to the intent of the testator only within the limits of the rules of law fixed by statute and decisions of our courts. Dearman v. Bruns, 11 N.C. App. 564, 181 S.E. 2d 809, cert. denied, 279 N.C. 394, 183 S.E. 2d 241 (1971). One such rule, applicable here, was established by our Supreme Court in Hodges v. Stewart, 218 N.C. 290, 10 S.E. 2d 723 *721(1940). There, the testator attempted to devise out of a total holding of 165 acres “25 acres of the home tract of land including the building and outhouses. . . .” In affirming the trial court’s ruling that the attempted devise failed for vagueness, the Hodges Court held:
The will furnishes no means by which the twenty-five acres can be identified and set apart, nor does the will refer to anything extrinsic by which the twenty-five acres can be located. The will fixes no beginning point or boundary. It is too vague and indefinite to admit of parol evidence to support it. There is nothing to indicate where or how the testator intended the twenty-five acres should be set apart out of the 82 acres in the home tract. The principle is firmly established in our law that a conveyance of land by deed or will must set forth a subject matter, either certain within itself or capable of being made certain by recurrence to something extrinsic to which the instrument refers. It is essential to the validity of a devise of land that the land be described with sufficient definiteness and certainty to be located and distinguished from other land. [Emphasis added.]
218 N.C. at 291, 10 S.E. 2d at 724. The only difference between this case and Hodges lies in the words “immediately surrounding.” These fix no beginning point or boundary, however. They do not indicate how the 30 acres are to be separated from the other land, except by mathematical speculation. They are thus too vague and indefinite “to admit of parol evidence to support them.” Id. Therefore, the trial court erred in implicitly ruling, as it must have to consider defendant’s parol evidence, that the devise was only latently ambiguous. A fortiori, the summary judgment based thereon also constituted error.

Defendant attempts to distinguish Hodges, citing Redd v. Taylor, 270 N.C. 14, 153 S.E. 2d 761 (1967), in which a devise of “the part of the Farm . . . that they want” was held valid. The testator and devisees in Redd had agreed prior to the testator’s death which land would pass, however, and the land was described in a lease between them. The Court specifically distinguished Hodges, on the ground that that case had required a separation, while Redd required only an “identification,” by *722means of the testatrix’s declarations and documents in existence during the testatrix’s lifetime. Plaintiffs advance no extrinsic evidence existing before the testator’s death to support their claim.
In Cable v. Hardin Oil Co., 10 N.C. App. 569, 179 S.E. 2d 829, cert. denied, 278 N.C. 521, 180 S.E. 2d 863 (1971), we upheld a devise of 25 acres out of a 73 acre tract. There, however, the will specifically provided that the tract was “to be selected” by the devisee. The express grant of a power of selection took Cable out of the rule of Hodges. No such express grant to defendant appears in this will. Although her powers as trustee are extensive, they do not include the power to transfer portions of the trust assets to selected individual beneficiaries. We therefore must hold that Hodges applies, and that the devise must fail.
VI
Relying on Taylor v. Taylor, 45 N.C. App. 449, 263 S.E. 2d 351, rev’d on other grounds, 301 N.C. 357, 271 S.E. 2d 506 (1980), defendant contends that if the devise of 30 acres fails, the residuary clause must fail as well. Taylor concerned a specific devise of the “remainder of my real estate,” which we held must fail with the overly vague devise of the home and “30 Acres of land surrounding the same,” since the remainder clause depended on the first for its determination. Here on the other hand there was an independent and effective general residuary clause, absent in Taylor. Therefore Taylor is distinguishable and the devise of testator’s real estate to the trust may stand.
VII
We are aware that our result, mandated by Hodges, is contradictory to the express intent of the testator. Hodges has been criticized as imposing too strict a requirement, most recently in Taylor v. Taylor (Robert M. Martin, J., dissenting). See also Annot., 157 A.L.R. 1129 (1945). Judge Robert Martin explicitly invited the Supreme Court by his dissent in Taylor to reconsider Hodges. In reversing on other grounds, the Supreme Court implicitly refused to do so. Because defendant has failed to show why Hodges should not apply, Hodges must supply the rule of de-*723cisión. Therefore, the order must be vacated and the cause remanded for proceedings consistent with this opinion.
