L'auteur ne voit entre H. strigosa Rehder et H. aspera Don 

 qu'une difference infime, la pilosite. II reunit les deux especes. H. 

 strigosa Rehder ne sera qu'une simple variete' se rattachant au type.

Mackenzie, K. K., Notes on Carex. X. Carex rosea Schk. and 

 its allies. (Bull. Torrey Bot. Club. XLIII. p. 423—434. 1916.) 



This paper contains a critical examination of the plants, deter- 

 minated as C. rosea Schk. The author distinguishes between this 

 species, C. radiata (Wahl.) Small and a new species C. convoluta 

 (C. rosea Boott, C. rosea var. pusilla Peck). The three species are 

 described, and notes are added on synonymy and distribution. The 

 chief difference between C. rosea and the other species lies in the 

 Stigmas being slender, not twisted, elongated and light brownish 

 red in C. rosea and stouter, twisted, short, deep brownish red in 

 the other species. C. convoluta has leaf-blades averaging 2,5 mm. 

 wide; spikes usually with nine to twelve perigynia; perigynia 

 3.25 — 4.5 mm. long, widely radiating. C. radiata has leaf-blades 

 averaging little more than 1 mm. wide; spikes usually with two to six 

 perigynia; perigynia 2.5—3 mm. long, more ascending. The three 

 species are widely distributed. Jongmans.

This paper contains short notes on localities of a number of 

 miscellaneous species and extensive notes on the genus Commelina 

 in the United States. These notes contain a key to the species 

 and an enumeration of the different species with extensive remarks 

 on their distribution, on the synonymy and the flowering. No new

Pennell, F. W., Notes on plants of the southern United 

 States. II. (Bull. Torrey Botan. Club. XLIII. p. 407—421. 1916.) 



In the present paper are given some notes on miscellaneous 

 species. The differences between Yucca glauca Nutt. and a doubt- 

 ful specimen of Yucca are pointed out. Schoenocaulon Drummondii 

 A. Gray and S. texanum Scheele are hitherto confused. However 

 they can be distinguished very well. Their occurrence in Texas 

 is listed here. The third part of the paper contains a revision of the 

 subgenus Nemexia of Smilax as occurring in the Eastern United States 

 with a key to the species and extensive notes on the distribution. 



New names: Smilax leptanthera Pennell sp. nov. (Georgia), clo- 

 sely allied to 5. tamnijolia Michx. S. biltmoreana (Small) J. B.Norton
