that ît is now generally conceded tliey forin one species. As is so 

 often the way condylocarpus is made the type by Ascherson 

 and Graebner l and the real type (Chamisso's) put under anotlier 

 haine. They do not notice Celakovskys 2 , or Caspary's referances 

 to the species. The proper name for Tausch's plant as a variety 

 of trichoides , seems to be (3 tuberculatus Sonder FI. Hamb. 101, 

 1850, as he expressly refers to Guépin, Fieber, Tausch, and 

 Reichenbach.

In the Flora Capensis VII, 49, 1897, I referred Woods (3055) 

 Natal plant to F. Friesii Rupr. It came to me labelled « P. obtu- 

 sifolius M. et K. ». The following in the herb. Delessert as well as 

 Wood's plant must be referred to P. pusillus L. var. africanus 

 Ar. Benn. 



1. P. peetinatas L. n° 1656. Transvaal, 1883, D r F. Wilms. 



2. P. ruiiliis Wolf. n° 1657. Transvaal, 1894. D 1 F. Wilms. 



3. P. striatum R. et P. Drege, n° 4458. Port Natal. 1839. 

 Umlazi River. 



4. P. Drege n° 1206, 1839, Port Natal. Between Tyger 



Berg and Blue Berg. 



This dift'ers for typical pasïlhis m the medial keel (carina) of 

 the fruit being about obsolète, the style strictly central, central 

 nerve of the leaves much wider and with cancellate areolation. 



15. P. filiformis Pers. var. occidentalis (Robbins). — 

 « Potamogeton. — Région of the Gunnison Watershed. West 

 Central Colorado. C. F. Baker, n° 828, 1901. » 



This seems to belong to P. filiformis Pers. var. occidentalis 

 Robbins (sub marinus) in King's Explor. of the 40 {h Mer. 

 USA. 1871. 



My spécimens gathered by Clitford Richardson from the 

 « Shonshone Geyer Basin Wyoming, USA. » seem quite the same 

 thing, and thèse are quoted by Morong 3 , as the same as the 

 original spécimens gathered by Watson in Ruby Lake, Nevada. 



What seems to me to be the same plant as this from Asia, — 

 « Mongolia Ordos. leg. N. Potanin. 1884 ».
