A second table presents the series of species under the horn- 
blendic and augitic divisions, in the order of their variation in 
form and composition from the typical species, hornblende and 
augite ; and the tendency to foliated crystallizations, as the spe- 
cies become hydrous is illustrated. Anthophyllite is placed as 
intermediate between true hornblende and hornblendic talc, while 
diallage, in the augitic series, is intermediate between true augite 
and augitic talc. 
Arr. VI.—Remarks on Menovors, Humb. §& Bonpl., and Bou- 
_ varia, Cham. & Schlecht.; by Asa Gray. 
Havine been requested to report upon a collection of plants 
made last year, en route from Texas to El Paso, New Mexico, by 
Mr. Wright, while attached to Col. Graham’s surveying party, I 
have been led, in anticipation of the regular study of the Mono- 
pelale of various collections now in my hands, to inquire whether 
Bolivaria is or is not generically distinct from Menodora. The 
latter genus was established on a Mexican plant, by Humboldt 
and Bonpland, in their Plantes Azquinoctiales, 2, p. 98, t. 110, 
and is re-deseribed by Kunth, in the Nova Genera et Specie 
Plantarum, 7, p. 199, from a specimen not in fruit. The for- 
mer was founded by Chamisso and Schlechtendal, in the first 
volume of the Linnea (1826), on two Buenos Ayrean species. 
The question of the order to which these plants should be refer- 
red, has, perhaps, been sufficiently discussed by Lindley,* who 
says they are genuine Jasminaceous plants; by Grisebach,t who 
created for them a distinct family, Bolivariaceee ; and by Alphonse 
Candolle,t who again refers them to Jasminez. He n 
admit them to form a separate tribe in that small order, although 
he corrects Grisebach’s character of the estivation of the corolla 
Which is not contorted, as in Jasminum, but imbricative ). 
considers the remaining and more important character of the four 
ovules in each cell of Bolivaria to be invalidated by the single 
pair in each cell, attributed to Menodora.
