4. C. incana. L. — 13; foliolis obovato-lanceolatis subtus (prascipue foliis junioribus) 
aureo-sericeis. 
This is probably a distinct species, but our materials are scarcely sufficient to afford good charaeters. It 
is smaller, the young branches and under-side of the leaves very silky, and often inclined to a golden hue. 
The leaflets are obovato-laneeolate. 
5. C. longirostrata ; sufFruticosa, ramis elongatis glabris, foliis trifoliolatis, foliolis 
obovato-cuneatis obtusis mucronatis supra glabris viridibus subtus incanis brevissime 
appresso-pilosis, stipulis bracteisque minutis subulatis deciduis, racemis elongatis multi- 
floris terminalibus lateralibusque, calycibus glabriusculis, carina longe rostrata. — Hab. 
Talisco. 
This seems to be a tall growing plant, with small leaves, the leaflets but little more than half an inch long : 
the racemes a span long, man^^-flowered ; the beak of the carina, which is suddenly curved up at an angle, is 
very long, and not at all ciliated. 
1. Trifolium repens. L.f 
The head of flowers is metamorphosed into small leaves. 
1. Dalea verbenacea ; sericeo-tomentosa erecta ramosa fruticosa, foliolis bijugis cum 
impari obovatis subtus prascipue nigro-punctatis, stipulis bracteisque subulatis, spicis in 
ramis copiosos terminalibus oblongo-cylindraceis, calycibus striatis subeglandulosis. —

Of this plant we possess a specimen gathered in Mexico by Schiede, and named D. verbenacea, from the 
Berlin Museum. It is a little less silky than our plant, but in other respects the same. The stems are 
woody, tall, much branched, and almost every branch is terminated with a spike of purple flowers, having 
very silky calyces, and of which spike the rachis is very thick, cylindrical, pitted with depressions for receiving 
the flowers. Legume ovato-subrotund, laterally compressed, indehiscent, 1 -seeded. 
2. D. argyrostachys ; erecta ramosa fruticosa, foliolis 10-14-jugis ellipticis carnosis 
parvis brevissime petiolulatis glabris subtus grosse nigro-punctatis, racbi plana ad inser- 
tionem foliolis dentata, spicis terminalibus elongatis, bracteis lanceolato-acuminatis deciduis 
calycibusque pulcherrime nitido-sericeis, dentibus calycinis subulatis longitudine florum. 
At first sight this has the appearance of D. alopecuroides ; but the stems are altogether shrubby, the leaves 
fleshy, and the leaflets smaller, decidedly elliptical, obtuse at the base, where the little petiole is inserted. 
The rachis is broad and flat. The spikes are long and broad (in consequence of the rather large flowers), 
most beautifully silky, and the teeth of the calyx are equal in length with the corolla, which latter appears to 
be yellow. 
3. D. crenulata ; fruticosa glaberrima ramosa, ramis erectis virgatis brevibus, foliis 
saepe in ramos brevissimos floriferos, foliolis 3-6-jugis parvis ellipticis crenulatis supra 
(sub lente) oblique lineatis, racemis brevibus plurifloris, calycibus obovatis sulcatis denti- 
bus late ovatis acutis brevibus, petalis longe exsertis, bracteis minutissimis. 
Whole shrub of a dark-purplish hue, as is the following. — A most distinct and well-marked species. Every 
leaflet is distinctly crenulated all round the margin. Found at Talisco.
