86 PLANTS WRIGHTIAN^. T. 



Auo-. " In dense bunches ; flowers yellow." — This so much resembles B. brachy- 

 phylla (Clavigera brachyphylla, Gray, PI. 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. Eiddellii, but rather more so 

 than in B. cylindracea), while in B. brachyphylla it is even plumose. The heads 

 are more corymbose, and on longer, simple, and naked peduncles. 



250. B. CYLINDRACEA, Gray, PI. Lindh. 2. p. 218. Frontiers of Western Texas. 

 A small state, scarcely a foot high; also collected in 1851. It was gathered in 

 Eastern Texas by Berlandier, whose specimen is placed by De Candolle with B. 

 Cavanillesii. 



251. B. RENiFORMis (sp. uov.) : subpuberula; ramis ad apicem usque foliosis ; fo- 

 liis plerisque alternis reniformibus vel ramealibus dilatato-deltoideis grosse crenatis 

 membranaceis longiuscule petiolatis ; capitulis parvulis in axillis pi. m. fasciculatis 

 brevissime pedicellatis folio brevioribus ; involucre 10-floro glaberrimo, squamis 

 omnibus obtusis, exterioribus ovalibus, intimis linearibus ; acheniis pubescentibus ; 



31. B. CouLTERi (sp. nov.) : suifruticosa ? ramis divaricatis pedunculisque pube brevi glandulosa sca- 

 bro-hirtellis ; foliis oppositis petiolatis hastato-triangulatis acuminatis marginibus utrinque laciniato-2 - 4- 

 dentatis (dentibus triangulari-subulatis) glanduloso-hirtellis mox glabratis ; pedunculis paucis corymbosis 

 gracilibus monocephalis ; involucre circiter 12-floro ; squamis subtriserialibus laxis, extimis lanceolatis 

 acuminatis; achenio puberulo. — California, Coulter (No. 293), in herb. Hook. — A branch only. 

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

 more in length. 



There is an allied species in Gregg's Mexican collection (No. 479) ; but my specimen is too poor for 

 characterizing it properly. 



***** Folia longe petiolala subcordata : capitula 7- \2-Jlora in corymbis paniculatis ramosissimis 

 effusis disposita : involucrum tantum hiseriale. 



32. B. DIFFUSA. Eupatorium diffusum, VaJil ; DC. Prodr. 5. p. 174. E. capillare, Desi). E. lep- 

 topodum, Gardner ! in Land. Jour. Bot. 5. p. 478. Bulbostylis diffusa, DC. Prodr. 7. p. 268. West 

 Indies, Mexico, Central America, Brazil. 



Bulbostylis scorodonissfolia, Kuntli, Ind. Sem. Hort. Berol. 1846, p. 12, would appear from the charac- 

 ter to be only B. Cavanillesii. 



Bulbostylis subuligera, Schauer in Linncea, 19. p. 718 (Zimapan, Mexico, Aschenlorn.), appears 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. I. c. (which came from Brazil), and the nine additional species described by 

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

 achenia ; while his Eupatorium leptopodum is Brickellia diffusa. 



Bulbostylis spinaciaefolia, DC. I. c, is likewise described with the achenia of Eupatorium. Except in the 

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

 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. Null. PL Gambel., is an obscure plant of uncertain genus, either of Asteroidese or 

 SenecionideJE.
