longe petiolulato multo majore lanceolato laciniati-dentato, foliis summis ses- 

 silibus palmatipartitis lobo medio sessili cseteris conformi, involucralibus lineari- 

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



ibus late memb 



subulato-spinescentibus calycis lobos 



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

 Hook §• Arn. On the Brazos, Texas, Drummond, Lindheimer, Wriyht. — The new 

 cliaracter here given is requisite now that the lower leaves are known. It is takcn 

 from Drummond's specimens in the Hookerian herbarium. 



231. E. Leayenworthii, Torr. ^ Gray, Fl 1. p. 604; Gray, Pl. Lindh 2. p. 

 209. On the San Pedro Eiver. 



232. Daucosma laciniatum, Engelm. Sf Gray, Pl. Lindh. 2. p. 210. Pebbly 

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

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

 ciadium.* 



233. Cymopterus montanus, Nutt. in Torr. 8f Gray, Fl. 1. p. 624; Gray, Pl. 

 Fendl. p. 56. Hills near Austin, Texas ; March (in fruit). Accords with NuttalPs 



with G 



the Hookerian herharium, exceut that the 



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

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

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

 lucels are smaller and less conspicuous thaii 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. ? 



Tauschia (Museniopsis) Texana {Gray, Pl. Lindh. 2. p. 211, adnof.): glaber- 



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

 pinnis 3-5 cum impari, 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 nuUo ; involuccllo 

 dimidiato e phyllo unico palmati 3-5-fido; radiis umbellulae fructu didymo brevi- 

 oribus ; mericarpiis Isevigatis 18 - 20-vittatis, jugis obsoletis. — "VVestem Texas, near 

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

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

* Thaspium Walteri, Shultleworlh, Pl. 



Wah. ?), from Macon 

 3. p. 175 (1843), from 



the same region (also gathered in the barreas 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. 



t Musenium divaricatum, Nutt. (which probably includes M. trachyspermum and M. angustifolium) 

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

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

 iection (referred to it by Hookcr), which is a Peucedanum, allied to P. triternatum.
