72 PLANTS AVRIGHTIAN^. VI. 



near Santa Cruz, Sonora; Sept. (1136.) — This, if I rightly remember, will nearly 

 accord with a plant gathered by Seemann, at Cerro de Pinal. 



B. BETONic^FOLTA (sp. nov.) : herbacea, pilis multiarticnlatis patentibus hirsuta ; 

 caulibus virgatis simplicibus ; foliis omnibus oppositis breviter petiolatis cordato- 

 oblongis obtusis grosse crenatis scabro-hirtellis triplinerviis subtus rngoso-reticulatis, 

 floralibus decrescentibus nunc parvis subsessilibus ; capitulis pedicellatis in thyrsum 

 terminalem racemosnm elongatum laxum superne nudum digestis ; pedunculis sin- 

 gulis 2-5-cephalis ; involucro r3-floro laxo, squamis 2 — 3-serialibus lanceolatis et 

 linearibus acuminatis, extimis brevibus ciliatis ; acheniis sericeo-villosis ; pappo 

 scabro. — Hills, near the copper mines. New Mexico ; Oct. (1137.) — Stems sev- 

 eral from the same perennial root, 2-3 feet high, roughish-hirsute, or nearly hispid, 

 terminating in a raceme-like, loose and interrupted, nearly leafless, virgate thyrsus, 

 of a foot or more in length. Leaves as long as the internodes, rather rigid, but 

 not coriaceous, very veiny underneath with coarse reticulations, 1^ to 2i inches 

 long, all more or less cordate at tlie base ; the petioles distinct, but only a line and 

 a half in length. Peduncles and pedicels 3 to 9 lines long, hirsute and somewhat 

 glandular. Heads 5 or 6 lines long ; the involucre and the pappus nearly as in 

 B. Wislizeni. — This species should stand next to B. cylindracea and B. Wislizeni, 

 to which it is more closely related than to any of the section which contains B. 

 Cavanillesii, notwithstanding the cordate leaves. 



B. BETONic.EFOLiA, var. hvimilis ; foliis parvulis (majoribus sesquipollicaribus) sub- 

 sessilibus. — Hills east of Santa Cruz, Sonora ; Sept. (1138,) 



B. CYLINDRACEA, Gro)/ ; a small variety. Western Texas ; May. 



B. Wrightii (sp. nov.) : suffruticosa, minutim glanduloso-scabrella ; caulibus ra- 

 mosissimis ; foliis plerisque alternis longe petiolatis deltoideo-ovatis (basi truncatis 

 subcordatisve) acutis grosse-serratis subcoriaceis 3 - 5-plinerviis subreticulatis ; 

 thyrsis paniculatis polycephalis subfoliosis ; capitulis pedicellatis ; involucro cylin- 

 draceo li-lS-floro glabro purpurascente, squamis 3-4-seriatis obtusis, extimis 

 ovalibus, intimis oblongo-linearibus ; acheniis hirto-puberulis ; pappo scabro. — 

 Hills, near the copper mines. New Mexico; Oct. (1139.) — Stems 3 or 4 feet 

 high, paniculately much branched, smooth ; the branches, &c. very minutely gland- 

 ular-scabrous. Leaves from the base of the stem not seen ; the upper cauline all 

 alternate, ly to 2 inches long, and the petioles i to | inch long ; those of the flower- 

 ing branches similar but smaller, not numerous. The leaves are rigid, but not so 

 coriaceous as those of B. baccharidea, not much reticulated. The very numerous 

 heads are larger than in the last-named species (about 5 lines long), and the inflo- 

 rescence more open. Pedicels It to 3 lines long. The scales of the involucre are 

 nearly all tinged with purple, especially above the middle. In the arrangement of 

 the species published in PI. Wright, p. 84 - 86, this would stand between B. bac- 

 charidea and B. reniformis. It is probable that its lower leaves are cordate. 



B. TEX ERA (sp. nov.): herbacea, puberula; caulibus adscendentibus ad apicem 

 usque foliosis ; foliis omnibus alternis longe petiolatis deltoideo-ovatis obtusis vel 

 acutis crenato-dentatis membranaceis basi trinervatis in petiolum breviter attenuatis ; 

 capitulis axillaribus subsolitariis vel paucis in ramulos floridos petiolum baud su-
