lelis semine multo minoribus: cet. F. radiate sed fructu mi- 
nore. — Thickets in light soil, near San Antonio, New 
Braunfels, &c. March. This, Dr. Engelmann, probably 
with good reason, considers as distinct from the F’. radiata 
with glabrous fruit (the form that alone occurs around St. 
Louis.) ‘The fruit is not only much smaller and more slen- 
der than that of EF. radiata, but the proportion of the empty 
cells is different ; these being much smaller than the seed; 
while in the former they are about equal, and in F’. carinata 
(which has a different habit) larger. Cauline leaves often 
deeply dentate at the base, or almost pinnatifid, but some- 
times entire.” Engel.’

408. Vernonia LinpHeEmmerR!I: perennis, bipedalis; foliis 
anguste linearibus confertis sessilibus uninerviis margine re- 
volutis supra glabris punctatis subtus cauleque simplici seri- 
ceo-tomentosis; capitulis corymbosis breviter pedunculatis 
30—40-floris; squamis involucri cano-tomentosi pappo rubi- 
ginoso brevioribus conformibus appressis oblongis obtusis 
exappendiculatis ; acheniis glabris 10-costatis glandulosis ; 
pappo exteriori multisquamellato. Gray & Engelm. in Pro- 
ceed. Amer. Acad. 1. p. 46.— Rocky hill sides, and high 
rocky plains, near New Braunfels, &c. July, August. Also 
near Seguin, &c. Mr. Wright. A very well-marked and hand- 
some species. In cultivation in the Cambridge Botanic Gar- 
den, it does net blossom until near the end of September. 
1 From the collection of 1849, Dr. Engelmann has communicated the characters 
of another species, viz. 
FepiA AMARELLA (Lindh. Mss.): “glaberrima, erecta, versus apicem dicho- 
tomo-cymosa; foliis inferioribus spathulatis basi longe attenuatis, superioribus ob- 
longo-linearibus sessilibus vel basi subcordatis, omnibus integris obtusis ; fructibus 
. Minimis subgloboso-ovatis obtuse auriculatis hispidis, loculis sterilibus fertili sub- 
globoso multo angustioribus brevioribusque pene obliteratis. —Comanche Spring; 
flowering in May.— Plant 8 to 12 inches high, in habit similar to F. radiata and 
F'. stenocarpa; but the leaves are entire in all the specimens ; and the fresh herb has 
a bitter taste, which the other species have not. The fruit is much smaller than 
in any other species known to me; the sterile cells many times smaller than the 
seed, their cavity almost obliterated.” Engelm.
