Ruins of Nohpat, Yucatan, collected i in flower, Nov. 24, 1865, by Dr. A. Schott, who, not only by his specimens, but 
= by — = — aided me in drawing up this dieaeetchdens — Habit of the plant very similar to that of the 
d var. conspicua ; about 20 feet high, branching abundantly from and near the base ; leaves in the specimens 
bade me “1416 sickens Jong and about 1 inch wide, thick, fleshy, smooth, but apparently not rigid, with extremely 
slight marginal asperities ; points of leaves in my specimens broken off. Panicle densely villous, bracts fleshy, whitish; 
flowers spreading about 2 inches, segments 14 lines long, less than half as wide ; pistil sisnilar to that of Y. aloifolia, 
but stamens much shorter and anthers smaller. It is quite possible that this plant is already in cultivation and 
may have received a name not known to me, but no accessible description agrees with it. [38]

m “Guatemala and Mexico” ; flowered in the Kew Gardens in September, 1871, whence through Mr. Baker 
I obtained dried specimens, That plant was 8 feet high, with leaves 24-3 feet long, and 24-3 inches wide ; panicle 
sessile between the upper leaves, ovoid, 2-3 feet long; flowers spreading siaigeiad 5 sez with narrow segments 
(3 inches long and }-1 inch wide) and, an unusual case, the inner ones narrower than the outer. ost character- 
istic part of the flower is the ovary, which is only twice as long (} inch) as we is thick, nee igs ona pe eacge style 3 
deeply and acutely bilobed nicaon stigmas ; the walls of the carpels are unusually thick, the ovules themselves have 
the diameter of others, but are very thick (0.5 mm.), indicating very thick seeds and a pulpy fruit, which will probably 
be also found short and thick. 
This species is said not to be rare in collections, but seldom to flower; it seems that it is often taken for Y. Dra- 
conis, and it really resembles the typical figure of that plant by Dillenius. In the botanic garden of Rome are several 
fine specimens named thus, which I scarcely hesitate to refer here ; they are 15-18 feet high, 1 foot in diameter at the 
enlarged base, not branched § ; leaves 24-2 feet long, 2-2} inches wide, much contracted above their very broad base, 
thin and somewhat flaccid or even pendulous, glossy on the upper sistas, delicately serrulate and with a very weak 
point.. The plants have not flowered f

rth Carolina to Florida on sandy tines — All the specimens I have seen came from South Carolina, 
and role to the principal form. Their stem is from a few inches to 4 or 6 feet high and 4-6 inches in diameter, 
simple or with a few branches, and even ee oldest ones entirely covered with a shaggy coat of old withered pendant 
eaves. Leaves 2-2} feet long and 13-2} inches wide, stiff, s sharply pungent, very frequently longitudinally folded, 
the narrower ones sometimes even. The edge of the young leaf is pale and usually delicately serrulate toward the 
ase; later it turns brown and brittle, the asperities disappear, and it is apt to crumble off or occasionally to detach 
itself in a few fibres. The surface of the leaf is of a dull, often pale or glaucous green, and on the under side, espe- 
cially towards the tip, rough with small asperities. The panicles (2-4 feet long, 1-14 feet in aang contracted 
upward and downward, where the flowers often spring directly from the main axis) are raised above the leaves on 
a stalk of their own length or shorter, beset with herbaceous bracts, lanceolate from a broad base ; coma bracts of 
same shape, small and membranaceous; panicle, or at least the pedicels, often pubescent, or nearly or quite glabrous, 
® Shoots have been cut off from the base! These cultivated plants are often altered in appearance by trimming and by the 
removal of the dead leaves, which left to nature would continue to cover the trunk for several feet below the living leaves, —«
