the involucre shorter and more imbricated (the scales ovate or oblong 

 and obtuse) than W. strigulosa, DC. which (in part), along with W. 

 scahriuscida, glahrata, and canescens, DC, I refer to W. hijiora. 



300. '■'■ Geniostoma crassifolium, Benth." is also G. rupestre var. pti- 

 herulum, Gray, in Proceed. Amer. Acad. 4, p. 321, a form of 301. 



304. " Gcertnera, sp." is a new Geniostoma, with small leaves. 



303. ^^ Gcertnera pyramidalis, Seem." is Couthovia corynocarpa, Gray. 



305. " G. barbata, Seem." is a Couthovia, which, if truly distinct from 

 the preceding, should be named C. Seemanni. The materials collected 

 by Dr. Seemann, comprising flowers and fruit, confirm the genus Cou- 

 thovia, and fix its position in the vicinity of Strychnos, calling, however, 

 for some extension of the character of Bentham's third tribe. There 

 are indications of dimorphism, or incipient difference in sex, in the 

 flowers examined. Some corollas of C. corynocarpa are beardless, or 

 nearly so, and have the anthers almost sessile in the throat, while 

 others of the same cyme are conspicuously bearded in the throat, and 

 their equally subexserted anthers are borne on filaments of their own 

 length, inserted some way down on the tube. The style is sometimes 

 slender and exserted, sometimes shorter or very short ; the ovary in 

 the latter is certainly fertile.* 



306. '■^ Fagrcea viridijlora. Seem." This wholly accords with F. 

 gracilipes, Gray, 1. c, which was thought to have white or cream- 

 colored corollas. 



307. '■^ Fagrma Vitiensis, Seem." is not in the collection of the 

 Amei'ican Expedition.
