TRANS. OF THE ACAD.' OF SCIENCE. 
5 or 6 triangular scales, but no spines ; long tube with about 
8 scales; crown of exterior stamens distant from the others 
.8 or 9 lines; about 10 filifofm spreading stigmas; fruit irre¬ 
gularly oval, about 2 inches long, naked, deep violet purple, 
at last barsting and dropping.seeds and pulp; seed quite 
different from that of the last species, very obliquely obovate, 
almost curved from a narrow base, with an orbicular hilum, 
0.9 1. long, smooth, shining, with a few irregular dots. 
Through the kindness of Dr. A. W. Chapman, of Apalachi¬ 
cola, Florida, I have received living specimens and fruit of 
the little southeastern sea coast' Opuntia, so that I can now 
complete and correct the description of this very distinct 
species. 
Opuntia Pes Corvi , Le Conte in herb.; Engelm. App. to 
Syn. Cact. in Proc. Am. Acad. A. & S. 3, p. 346; Chaprn. 
South. Flora, p. 145: laete viridis, diffusa; articulis parvis 
ovatis seu obovatis tumidis saepius teretiusculus fragilibus; 
pulvillis pulvinatis; foliis ovatis cuspidatis incurvis; areolis 
junioribus albo-tomentosis setas parcas brevissimas pallidas et 
plerisque aculeos 1-3 rectos rigidos saepe basi compressos 
tortosque obscuros gerentibus, infimis inermibus; floribus 
minoribus flavis; ovario obovato pulvillis perpaucis fusco- 
villosis stipato; sepalis exterioribus ovato-lanceolatis, interi- 
oribus obovatis cuspidatis; petalis sub-5 obovatis spatulatis 
obtusis ; stigmatibus 4-5 erectis; seminibus paueissimis 
anguste obtuseque marginatis in pulpa viscosa baccse saepe 
floris rudimentis coronatae nidulantibus. 
Barren sands along the coast of Georgia and Florida. 
Joints 1-3 inches long, obovate, tumid, or narrower and sub- 
cylindric, usually many of them growing in the same season,, 
one from the top of the last one, till they at last become 
prostrate, and 1 or 2 feet long; pul villi somewhat prominent, 
4, 6, or even 8 lines apart; leaves 2^-35 1. long; spines 1-1^ 
inches long, very straight, when in threes, divergent. Flow¬ 
ers li-l§ inches in diameter; sepals and petals less numerous 
and narrower than in any allied species; ovary \ inch long, 
with only 2 or 3 areolae on its surface, and 3-5 on its upper 
edge. Fruit obovate, 6-7 1. long, rose-purple, with a shallow 
umbilicus, areolae almost obliterated; seeds 2 1. in diameter, 
1-3, rarely as many as 5, in one fruit. Evidently near 0 . 
vulgaris , from which the shape and armature of the joints 
sufficiently distinguishes it ; far removed from 0 . fragilis , 
with which, at first glance, the tumidity and fragility of the 
joints would seem to connect it.
