Calyx e sepalis 5 angustissimis. Corolla tubuloso-infundibuli- 

 formis, limbo 5-Iobo. Stamina 5, ina^quilonga ; filamentis inappendi- 

 culatis corollaj tubo intequaliter adnatis. Stylus filiformis, apice 

 bifidus ; stigmata capitellata. Ovarium biloculare : ovula in loculis 

 gemina, anatropa, ex apice fere placentae nerviformis pendula. Cap- 

 sula globosa, subdidyma, membranacea, loculicida, valvis a dissepi- 

 mento utrinque dispermo solutis. Semina loculos replentia, facie con- 

 cava medio carinata. — Herba multicaulis, humilis, sericeo-pilosa ; 

 caulibus diffusis basi lignescentibus ; foliis oppositis ovatis penniveniis

Draperia systtla, Torr. Nama systyla, Gray in Proceed. 

 Amer. Acad. 6, p. 37. California, Lobb. ; in the Yosemite Valley, 

 Brewer, Torrey, Bolander ; Northern California, A. Wood; Nevada Co., 

 Miss N. J. Davis. This genus, particularly interesting as a transition 

 from the Hydrolece to the proper Hydrophyllacece, is dedicated to Profes- 

 sor John W. Draper of New York, author of a Treatise on the Forces 

 which produce the Organization of Plants, and of other distinguished 

 physiological and philosophical works. It was first detected by Mr. 

 Lobb (station not recorded), and briefly characterized by Dr. Gray 

 as a Nama, without examination of the interior of the ovary of the 

 fragment sent to him by Dr. Hooker. With the corolla and nearly the 

 androecium of that genus it combines the gynaicium and seeds of 

 Phacelia proper, except that the ovary and pod are two-celled, and the 

 opposite leaves are peculiar. The embryo has not been found, even 

 in apparently full-grown seeds. J. Torrey.

 ginato superne folio solitario lineari instructo ; ligula elongata acuta; 

 vaginis laxis striatis ; spica solitaria basi vaginata ; spiculis unifloris ;
