V. PLANTS WRIGHTIANiE. 79 



longe petiolulato multo majore lanceolate laciniati-dcntato, foliis summis ses- 

 silibus palmatipartitis lobo medio sessili cteteris confoimi, involucralibus lineari- 

 lanceolatis spinuloso-laciniatis capitulum globosutn duplo superantibus ; paleis lan- 

 ceolatis lateribus late membranaceis apice subulato-spinescentibus calycis lobos acu- 

 minato-aristatos vix superantibus, summis foliaceis capitulum coronantibus. — E. 

 coronatum, Ton: 8c Gray, Fl. 1. p. 604 ; Engehn. Sf Gray, PI. Lindh. p. 10, non 

 Hook. ^ Am. On the Brazos, Texas, Drummond, Lindheimer, Wright. — The new 

 character here given is requisite now that the lower leaves are known. It is taken 

 from Drummond's specimens in the Hookerian herbarium. 



231. E. Leavenworthii, Torr. 8f Gray, Fl. 1. p. 604; Gray, PI. Lindh. 2. p. 

 209. On the San Pedro River. 



232. Daucosma laciniatum, Engelm. §• Gray, PI. Lindh. 2. p. 210. Pebbly 

 bars of the Rio Nueces (in flower and in fruit). — It occurs with perfectly ripe 

 fruit in Lindheimer s collection of 1850. The genus should stand next to Cynos- 

 ciadium.* 



233. Cymopterds montanus, Nutt. in Torr. Sj" Gray, Fl. 1. p. 624 ; Gray, PL 

 Fendl. p. 56. Hills near Austin, Texas ; March (in fruit). Accords Avith Nuttall's 

 and also with Geyer's specimens in the Hookerian herbarium, except that the fruc- 

 tiferous peduncle is longer than the leaves, and the fruit is not quite so large. The 

 carpophore persists when the mericarps fall, as in Fremont's specimens. Like 

 Nuttall's and Geyer's specimens, moreover, the silvery-scarious involucre and invo- 

 lucels are smaller and less conspicuous than in Fendler's plant (No. 275), which 

 also has larger wings to the fruit. Like Fendler's, but still larger, are the silvery 

 involucres of specimens gathered by Burke at " Portneuf River," which are just 

 coming into flower. Can they belong to C. albiflorus, Nutt. ? 



I Tadschia (MusENiopsis) Texana (Gray, PL Lindh. 2. p. 211, adnot.): glaber- 

 rima; foliis omnibus radicalibus utrinque viridibus pinnato-decompositis, nempe 

 pinnis 3-5 cum imparl, inferioribus petiolulatis (petiolulis ac petiolo gracili apteris) 

 pinnato-3-5-partitis, segmentis cuneiformibus 3-5-fidis, lobis oblongis obtusissi- 

 mis ; scapo simplicissimo nudo ; involucro parvo 1 - 2-phyllo aut nullo ; involucello 

 dimidiate e phyllo unico palmati 3 - 5-fido ; radiis umbellulfe fructu didymo brevi- 

 oribus ; mericarpiis laevigatis 18 - 20-vittatis, jugis obsoletis. — Western Texas, near 

 Austin. Galveston Bay, Drummond (No. 109 of the third collection) in herb. Hook. 

 — No. 2760 of Galeotti's Mexican collection is the same as No. 121 of Coulter's, 

 viz. Tauschia Coulteri (PL Lindh. L c). f 



* Thaspium Walter!, ShuUleworlh, PL Rugel, exsicc. (Apium bipinnatum, Walt. ?), from Macon 

 County, North Carolina, is the same as Zizia pinnatifida, Buckley, in Sill. Jour. 45. p. 175 (1843), from 

 the same region (also gathered in the barrens of Kentucky by Dr. Short). It is hard to say whether the 

 plant should be referred to Ziz'a or Thaspium ; — probably to the latter. 



+ Musenium divaricatum, NuU. (which probably includes M. trachyspermum and M. angustifolmm) 

 has scabrous fruit, crowned with conspicuous and persistent calyx-teeth. Of M. (Daucophyllum) te- 

 nuifolium, Null., the fruit is unknown. To it however does not belong No. 220 of Geyer's Oregon col- 

 lection (referred to it by Hooker), which is a Peucedanum, allied to P. triternatum.
