This so miich resembles B, brachy 



phylla (Clavigera brachyphylla, Gray, Pl Fendl p, 63) that it might well be taken 

 for a variety of it with toothed and mostly opposite leaves, except that its pappus is 

 barely barbellate under a lens (not as strongly as in B. Riddellii, but ratl 



than in B, cylindracea)

Leaves with the petiole scarcely an inchlong. Heads five lines long, on peduncles of half an inch or 



morc in length. 



There is an allied species in Grcgg^s Mexican collection (No. 479) ; but my specimea is too poor for 



charactcrizing it properly.

Bulbostylis scorodonia^folia, Kunth^ Ind, Sem. Hort. Beroh 1846, j?. 12, would appear from the charac- 

 ter to be only B. Cavanillesii. 



Bulbostylis subuligera, Schauer in Linnc^a^ 19. p. 718 (Zimapan, Mexico, Aschenhorn.)^ appeai^ to be, 

 as is stated, very closely allied to B. pedunculosa, DC, and if so it is a Eupatorium. 



Bulbostylis pedunculosa, DC. Prodr. 5, p. 138; Deless. Ic, Sel 4. t. 17, (as well De Candolle's own 

 specimens as those of Coulter^s Mexican collection, No. 251,) has the achenia merely 5-costate and at 

 length pentagonal ; besides, the corolla is considerably ampliate above and rather deeply cleft. It must 

 therefore be removed to Eupatorium, many genuine species of which have a bulbous base to the style. 



Bulbostylis glabra, DC. l. c. (which came from Brazil), and the nine additional species described by 

 Gardner, in Lond. Jour. Bol 5. p, 467-472, are all true Eupatoria, having pentagonal (not striate) 

 achenia ; while his Eupatorium leptopodum is Brickellia diffusa. 



Bulbostylis spinaciajfolia, DG. l c, is likewise described with the achenia of Eupatorium. Except in the 



larger leaves, it would seem to accord with Eupatorium hastile, Schauer in Linncia, 19. p, 719, to whlch 

 probably belongs No. 244 of Coulter's Mexican collection, from Zimapan. 



Bulbostylis triangularis, DC. Prodr. 7. p. 268, may be a Carphephorus. 



Bulbostylis ? pauciflora, DC. Prodr. 5. p. 139, should probably be restored to Eupatorium. 



Bulbostylis annua, Nutt. Pl. Gamhely is an obscure plant of uncertain genus, either of Asteroldese or 



Senecionidece.
