Plante Lindheimeriane. 211 
radios umbelle et umbellularum plurimos subsequantibus ; 
floribus albis. — Genus differt a proximo Cynosiadio petalis 
inflexis, ab Aithusa calyce 5-dentato, ab Ginanthi carpophoro 
distincto, etc. 
404, Davcosma taciniatum, Engelm. & 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. & 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.” ! 
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, Nuét., of which I have no specimens (since No. 220 of Geyer’s 
Oregon Collection does not agree with the generic character). 
Tavuscnia (MusEniopsis) Texana (sp. nov.): glaberrima; foliis omnibus radi- 
ealibus 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 dimidiato e phyllo 
unico palmati 3-5-fido; radiis umbellule fructu didymo brevioribus ; mericarpiis 
levigatis 18-20-vittatis, jugis obsoletis.— Western Texas, near Austin? Mr. 
Charles Wright.— Root thick, perennial. Scape in fruit from 5 to 8 inches high, 
longer than the leaves. Umbel 5-7-rayed. Fruits a line and a half long, very 
smooth ; the filiform juge 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 distinct species, viz. : 
Tauscuia Couttert (Gray § Harv. inéd.): breviter caulescens ; foliis ternati- 
quinatisectis subtus glaucescentibus; segmentis ovalibus basi subcordatis cuneatisve 
sepius trilobatis duplicato-dentatis, dentibus mucronatis ; involucro et involucello e 
phyllo unico lineari integerrimo aut nullo; radiis umbellule 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 7. 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 juge rather prominent; vitta 6 in each mericarp, 
rather large.
