ther on, through a lovely country, which, at that season, (August,) after 
the annual rains, was covered with a luxuriant vegetation. The eleva¬ 
tion of the country is here between 4,000 and 5,000 feet above the gulf. 
The rare Cevattia slnuata , which Dr. Gregg'' has also sent from Monte¬ 
rey, was found in this part of the journey^. Here also occurre<da jperemi ial 
species of Linum , with yellow petals, so -fe, 
mJfyelIo n Dp.iiliriipBfwnmti; it is distinguished by its long aristate sepsis, 
whence the name.* 1 Several Oemtherae , not seen before, made now 
their appearance; different species of Gilia, a number of Nyctagmeae, 
several Asclepiadaceae , Malvaceae, Cucurbitaceac, ComposUae , and others, 
were here collected; including a number of new species, which only want 
of time and references have for the present prevented me from describing* 
Sear lake Ehcinillas another Mnrtynia zt was found, which, in its foliage, 
domes nearer to M. proboscidea , but is readily distinguished by its purple 
flowers. A beautiful yellowrflowering bignoniaceous shrub, probably 
Tecoma starts, .Tuss., seen more frequently further south, was observed for 
the first time near Gallejo spring. • Shrubby Algarobiue were seen mqre # 
plentifully, as also some other Mimoseae. 
Here would be the proper place to introduce a notice of the several spe¬ 
cies of Yucca found by Dr. Wislizenus. But, unfortunately, the labels of f 
the specimens were partly lost, so that it is impossible at thisAime to ar¬ 
range leaves, flowers, and fruits properly. Certain it is that several spe¬ 
cies besides Yucca angustifolia, mentioned ibove, were seen; that the 
leaves of all of them have filamentose edges, some with very fine, others 
with very coarse fibres on their margin; that the majority bear juicele^s 
capsules with very thin, paperlike seeds, but that one species produces an 
edible succulent fruit with very thick seeds. Fortunately the seeds col¬ 
and long; flowers spotted, u yellow,” (Dr. W.,) a little smaller than in 
t M. proboscidea.

jfc In sandy’soil near Carizal, south Sf Ei Paso; collected in August, in 
flower and fruit. The rhizoma in the specimen before me is 6 inches 
long and 3 to 4 lines in diameter, white; stems numerous, 1 to 3 feet 
high, divaricately branched; upper leaves (lower not seen) 3 to 4 lines 
| long, sepals 4 lines long; flowers 10 lines in diameter; petals sulphur yel- 
f low; styles united for about three-fourths of their-length; capsule 2 lines 
\ long. 
2 2 Mdrtynia violacea, n. sp., annua, foliis alternis, cordatis ; repando- 
sinuatis, acute denticulatis, glabriusculis; bracteis lanceolatis calycfe 
obliquo, infra usque ad basin fisso dimidio brevioribus; staminibus 4; 
rostro pericarpium superante. 
Near lake Encinillas, north of Chihuahua, flowers August; leaves 4 to 6 
inches long, and nearly as wide, indistinctly sinuate-lobed, beset with 
• small, sharp, distant teeth, flowers from pale red to deep violet purple, as 
large as in M. proboscidea.
