firmness not known in other meadow-rues of the farther North. The 

 circinate character of the stigmas is striking, but occurs in one or more 

 other species. The specimens bear the number 19006 of the Geol. 

 Survey. 



919. Thalictrum glaucodeum Greene, 1. c, p. 55. — Rather slender, 

 2 feet high or more, with stem strongly striate-angled and glabrous, 

 simple, leafy up to the small and rather naked panicle; leaves rather 

 small and of many small leaflets, the basal not seen, the lower cauline 

 petiolate, the upper sessile, all of firm texture, glaucous on both faces, 

 but beneath almost white with bloom; terminal leaflets shortly and sub- 

 quadrately obovate, the largest barely 3 / 4 -inch long, 1 / 2 -inch wide under 

 the lobes, these 3, shallow, much broader than long, rounded, yet ab- 

 ruptely acutish, the base obtuse or subtruncate, the lateral leaflets not 

 much smaller, mainly not very dissimilar, but a few quite small round- 

 oval and entire, all leaflets marked underneath by a few very pro- 

 minently raised white veins and a thin indument of short white hairs; 

 panicle of fertile plant small but rather many-flowered and dense, its 

 branches glabrous, as also the calyx; pistils numerous, encircled by a 

 row of 3 to 7 or 8 stamens; filaments abruptly clavate above, but not 

 to the width of the mostly broad and merely oval (occasionally oblong) 

 anthers; immature carpels fusiform, substipitate, glabrous. — The type 

 specimen of this rather elegant and very pale meadow-rue is in the 

 herbarium of the Geol. Survey, under no. 869, and came from Tignish, 

 at the northern extremity of Prince Edward Island, where it was 

 obtained by Professor Macoun, 25 July, 1888. The flowers, though 

 mainly pistillate, are very fairly hermaphrodite. — A plant much like 

 this in habit, quite as pale with bloom, and even with very similar 

 foliage, is in the same herbarium from Boyleston, Nova Scotia, by 

 Dr. Charles A. Hamilton, July, 1890. It also has hermaphrodite flowers, 

 and in these the calyx is persistent and is of five or six narrow elliptical 

 sepals. This plant also I refer tentatively to T. glaucodeum, and hope it 

 may prove to belong with the more northerly and isular type.
