the number of involucral bracts which, according to Weddell, is 

 12-15. In the specimen at hand the involucre consists definitely 

 of 21 bracts, disposed in a single series. The subtending brac- 

 teoles are relatively conspicuous, yet they do not form a part of 

 the true uniseriate involucre; and on this account the plant in 

 question cannot be referred properly to Culcitium. In habit and 

 foliar characters Dr. Pennell's specimen simulates Culcitium 

 longijolium Turcz., but that species is described as having a mul- 



tiseriate involucre.

The specimens here cited agree in all details with the original 

 description of the above species by Professor Hieronymus. The

 3 dm. in length and from 1 to 2.5 dm. in breadth. The heads

 collected read, — "A loosely twining vine, to 20 feet. Moderately

 were collected Jan. 25, at 6000 feet. Flowers rich yellow; leaves 

 polished. This is one of the most showy species of the order; 

 a plant in full bloom is a fine sight."
