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 filiform spreading stigmas; fruit ^irre¬ 
gularly oval, about 2 inches long, naked, deep violet purple, 
at last bursting 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 hitum, 
0;9 J. 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.

Syn. Cact. in Proc. Am. Acad. A. & S. 3, p. 346 ; Chapm. 
South. Flora, p. 145: laete viridis, diffusa; articulis parvis 
ovatis seu obovatis tumidis saepius teretlusculus fragilibus; 
pulvillis pulvinatis;, foliis ovatis, cuspidatis incurvis; areolis 
junioribus albo-tomentosis setas parcas brevissimas pallidas et 
plerisque aculeos 1-3 rectos rigid os saepe basi compressos 
tortosque obscuros gerentibus, infimis lnermibus; floribus 
minoribus fiavis; ovario obovato pulvillis perpaucis fuscoT 
viliosis stipato ; sepalis exteripribtis ovato-lanceolatis, interim 
oribus obovatis cuspidatis; petalis sub-5 obovatis spatulatis 
obtusis ; stigmatibus 4-5 erectis; seminibus paucissimis 
anguste obtuseque marginatis in pulpa viscosa baccae saepe 
floris rudimentis corosatae 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; pulvilli somewhat prominent, 
4, 6, or even 8 lines apart; leaves 2^-3 h 1. long; spines 1-1 § 
inches long, very straight, when in threes, divergent. Flow¬ 
ers 1^-1 § inches iti 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 O . fragilis , 
with which, at first glance, the tumidity and fragility of the 
joints would seem to connect it.
