in tropical America, or even from Texas, at least in some cases, 
as there seems to be some variation in those from different locali- 
ties, for cultivating, and later escaped from gardens where it was 
planted. 
This is, perhaps, the Opuntia polyantha of Chapman’s ‘ Flora”’ 
as far as the Apalachicola part of the range given for that species 
is concerned. 
vg. Opuntia zebrina Small, sp. nov. 
Plant erect, more or less branched, throughout, fully 1 m. tall, 
or less, the roots fibrous: joints oval or obovate, thickish, mostly 
1-2 dm. long, Pas -green, sometimes obscurely glaucous: leaves 
ovoid, 2~3 mm. long, bright-green: areolae scattered, some of 
them, usually is lower ones, unarmed, the upper ones irregularly 
armed: spines slender, solitary or 2, 3, or 4, together, red-brown, 
finely banded, nearly terete, closely spirally twisted: flowers few 
on a joint, or solitary: sepals deltoid, to deltoid-reniform or 
nearly reniform: corolla yellow, rotate, 6-7 cm. wide; petals 
rather numerous, the inner ones broadly-obovate, undulate, 
minutely mucronate or notched at the apex: berries obovoid, 
not constricted at the base, 3.5-4.5 cm. long, red-purple: seeds 
many, 6~7 mim. in Cinmeier. [Plate 226.] 
Coastal sand-dunes, Cape Sable, Florida, and the lower Florida 
Keys.—Type specimens collected on Middle Cape Sable, Decem- 
ber, 1917, by J. K. Small, in the herbarium of the New York 
Botanical Garden. 
The only specimens collected on Middle Cape Sable on a 
cruise to that region in December, 1917, were plants of a prickly- 
pear. In spite of clouds of mosquitoes that almost defeated the 
securing of any plants at all, the writer and his associates managed 
to gather several bags of joints of an Opuntia that seemed dif- 
ferent from others heretofore observed by us in southern Florida. 
The discovery of this plant not only added a new species to 
our range, but also brought a series of hitherto more southern 
geographic range, into our limits. It is a conspicuous plant, 
not only on account of the contrast of its peculiarly deep-green 
joints and bright-yellow corollas, but also on account of its 
Vigorous growth and continuous healthy condition. A close 
examination reveals an armament not duplicated in our other
