MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [Vol. 9, No. 3 



I 



flowers minute, the calyx ca. 2.5 mm long; hypanthium minutely and very spar- 

 ingly glandular-puberulent; sepals broadly ovate, acutish, 1.5-2.0 mm long; 

 petals broadly elliptic-ovate, 2.0-2.5 mm long, carpels 3; styles 3, bipartite to the 

 base, the segments ca. 1.5 mm long, entire, obtuse or truncate; seed 0.3-0.4 mm 

 long, black, narrowly oblong-elliptic, more or less biapiculate, foveolate in ca. 

 10 vertical rows. 



TYPE: corolla pale lilac, wet places in savanna, between Esmeralda Savanna, 

 and southeastern base of Cerro Ouida, at 200 m alt., Terr. Amazonas, Venezuela, 

 August 22, 1944, Steyermark 60920 (Holotype, F; isotype, NY). 



Distribution. Known only by two collections, the type and Maguire, Cowan 

 & Wurdack 29612 from Cano Culebra, Cerro Duida, at 1600 m alt. 



The closest congener of D. esmeraldae seems to be D. pusilla H.B.K. This 

 latter species is more diminutive, pluri-scapose, with flowers about twice larger 

 (4-5 mm long), and seed subglobose. 



12. Drosera capillaris Poir. in Lam. Encyc. 6: 299. 1804, 

 ? D. tenella Willd. ex Roem. & Schult. Syst. Veg. 6: 763. 1820. 

 Type locality: Carolina, North America. 



Distribution. Moist sandy areas in the coastal U. S. from Virginia to Texas; 

 Central America; the West Indies; and South America from Venezuela to Brazil. 



Venezuelan and Guianan plants, so far as available material indicates, are 

 consistently smaller with conspicuously smaller flowers and seed. They seem 

 to fit the description of D, tenella, which may well represent a distinct geo- 

 graphical race of D. capillaris.
