128 PATAGONIAN EXPEDITIONS: BOTANY. 



STREPTANTHUS TEHUELCHES (Speg.) Gilg et Muschler. 



Syn. S. symbrium tehuelches Speg. Speg. Nov. Add. Flor. 

 Patag., IV., p. 218. Macl., p. 431. 



S. Patag., the east coast, central Patagonia, along Rio Mayo, Rio 

 Senger and Rio Chubut. 



HEXAPTERA Hook. 



H. NORDENSKJOLDI DuS. Macl., p. 425. 



Should be transferred to Hexaptera cuneata Gill, et Hook, as a variety 

 of that species. Its name thus: Hexaptera cuneata Gill, et Hook. var. 

 nordenskjoldi Gilg et Muschler. 



Add Macl., p. 426: To Lepidium bonariense L. the var. pinnatisecta 

 (Ok.), transferred from Roripa pubesc ens var. pinnatisecta, p. 435. 



P. 426 : Lepidimn pubescens Desv. is not a synonym of L. bonariense, 

 but a distinct species (fide Gilg & Muschler in Engler's Botan. Jahrb., 

 Bd. 42, p. 448). It occurs in Chili, Peru and California, is not known 

 in Patagonia. 



DELPINOELLA Speg. Macl., p. 427. 



This genus should be transferred to Coronopus as a section of that 

 genus ; thus Delpinoella patagonica Speg. becomes Coronopus patagonicus 

 (Speg.) Muschler. 



CORONOPUS VARIABILIS Phil. prol. PINNATISECTA O. E. Schuhr. Schuhr. 



Mon. Cardam, p. 432. 



S. Patagonia, Rio Sta. Cruz ; Central Patagonia, Rio Carren-leofu ; 

 S. Chili. 



CORONOPUS (L.) Gaertn. Macl., p. 427. 



The following summary of the Patagonian species of this genus is 

 based on the recent paper of Reno Muschler, in Engler's Botan. Jahrb., 

 Bd. 21, p. in. 



Note by Macloskie. Muschler's revision collects into one genus, Coro- 

 nopus (L.) Gaertn. about 45 species, of all countries, hitherto scattered 

 among half a dozen different genera; all of them short-fruited, and with 

 the characters of Coronopus as in Macl., p. 427, to which some negative 

 characters may be added ; that the fruits are not pendulous, nor winged,
