290 TROCEEDINGS OF THE AMERICAN ACADEMY 



U. LONGECILIATA, A. DC, IS already in the published lists. It is a 

 well-marked little species of Brazil, Guiana, and Cuba ; it was col- 

 lected by the late Dr. Garber in Florida, at Tam|)a and at INIunatee, 

 in 1877, but it did not reach me in time to be inckidcd in the lirst part 

 of the Synoptical Flora. 



U. siMi'LKX, C. Wright in Wright & Sauvalle, Flora Cubana, a 

 small and spicately several-flowered species (which may have some 

 earlier name), was collected by Miss Mary C. Reynolds at St. Augus- 

 tine, Florida, in the autumn of 1879. 



U. SUBULATA, L., var. cleistogama, seems to be not uncommon. 

 The late Dr. Garber collected it in Florida, and Mrs. Owen sends it 

 from the island of Nantucket. 



U. PURPUREA, Walt. In the Synoptical Flora it was questioned 

 whether the plant there described is the species of Walter, on account 

 of his " floribus parvis," those of the plant in view being '"over half- 

 inch broad," and the lips being spreading. My character was from 

 Northern specimens. I had some from Georgia and S. Carolina, of a 

 more slender plant with smaller flowers, which were thought to be 

 imperfectly developed. But Mr. Curtiss has since sent fine specimens, 

 answering to Walter's character, and to that of Chapman, who gives 

 the breadth of the flower at four lines. At the same time he sends 

 from Kastern Florida specimens exactly like the robust and larger- 

 flowered plant of the Northern States. Wright's Cuban specimens 

 seem to be intermediate. It remains to be determined whether the 

 U. saccata of P^lliott (the name of which Le Conte ignores) is the 

 large or the small-flowered species, and whether fresh flowers of the 

 two would furnish distinctive characters. If so, names for the two 

 species are ready. The plant mentioned in EU. Sk. i. 24, as probably 

 the U. purpurea of Walter, must rather have been a purplish-flowered 

 U. subidata. Walter evidently had a floating species in view. 



3. New Genera of Arizona, California, and Ihcir Mexican 

 Borders, and two additional Species of Ascleiyiadacece. 



The character of the first of these genera has already been printed 

 in the Bulletin of the California Academy of Sciences, 1884, no. 1, 

 p. 4.
