Plantce Lindheimeriance. 211 



radios umbellse et umbellularum plurimos subaequantibus ; 

 floribus albis. — Genus differt a proximo Cynosiadio petalis 

 inflexis, ab iEthusa calyce 5-dentato, ab CEnanthi carpophoro 

 distincto, etc. 



404. Daucosma laciniatum, Engelm. fy Gray. High val- 

 leys near New Braunfels and on the Upper Guadaloupe, cov- 

 ering large patches of moist prairie land, and along the 

 margin of thickets. Flowering in July. — The specimens 

 have only half grown fruit. The carpological characters of 

 the genus are derived from fruiting specimens of Lind- 

 heimer's collection in 1849, just received, and from others 

 gathered by Mr. Wright the same year, on sand bars of the 

 upper part of the Nueces. — The whole plant exhales a strong 

 odor of Carrot.

 fructu pubescente, Torr. fy Gray, Fl. 1. p. 638. Shady 

 woods, New Braunfels. April, May. " Less rigid and erect 

 than the form with glabrous fruit, from the same locality." l 



1 From Mr. Wright, gathered in Western Texas, we have specimens of an evi- 

 dent congener of Tauschia nudicaulis, except that its fruit shows about 20 small 

 vittE, instead of six rather large ones. In this and many other respects, it accords 

 with Musenium, Nutt., of which I have no specimens (since No. 220 of Geyer's 

 Oregon Collection does not agree with the generic character). 



Tauschia (Moseniopsis) Texana (sp.nov-): glaberrima ; foliis omnibus radi- 

 calibus utrinque viridibus pinnato-decompositis, nempe pinnis 3-5 cum impari, 

 inferioribus petiolulatis (petiolulis ac petiolo gracili apteris) piunato-3-5-partitis, 

 segmentis cuneiformibus 3 - 5-fidis, lobis oblongis obtusissimis ; scapo simplicis- 

 simo nudo ; involucro parvo 1 -2-phyllo aut nullo; involucello diinidiato e phyllo 

 unico palmati 3-5-fido; radiis umbellulse fructu didymo brevioribus ; mericarpiis 

 leevigatis 18-20-vittatis, jugis obsoletis. — Western Texas, near Austin? Mr. 

 Charles Wright. — Root thick, perennial. Scape in fruit from 5 to S inches high, 

 longer than the leaves. Umbel 5-7-rayed. Fruits a line and a half long, very 

 smooth ; the filiform jugaj nearly obsolete at maturity. — No. 120 of Coulter's 

 Mexican Collection is Tauschia nudicaulis, as appears from an original specimen 

 from Schlechtendal, in flower only. No. 121 is apparently a disiinct species, viz. : 



Tauschia Coulteri (Gray fy Harv. iried.) : breviter caulescens ; foliis ternati- 

 quinatisectis subtus glaucescentibus; segmentis ovalibus basi subcordatis cuneatisve 

 saepius trilobatis duplicato-dentatis, dentibus mucronatis ; involucro et involucello e 

 phyllo unico lineari integerrimo aut nullo ; radiis umbellulce fructu plus duplo lon- 

 gioribus. — Scapes in flower and fruit from 5 to 12 inches long, soon exceeding the 

 leaves. Petioles much dilated and sheathing at the base, as in T. nudicaulis. 

 The larger leaflets an inch and a half long. Pedicels in fruit 4 or 5 lines in length. 

 Fruit fully two lines long ; the jugae rather prominent ; vittae 6 in each mericarp, 

 rather large.
