BUDS AND STIPULES. 235 
PIPERACER. 
Peperomia trinervis, Ruiz & Pav.—The terminal bud consists 
of subsessile and sessile, convolute leaves, the outer of which 
covers two-thirds of all the younger members; the next younger 
leaf covers all the rest. The leaves attain some size before they 
unroll. 
The axillary buds are very small the first year they are formed 
and nestle in the concavity of the pedestal. They do not, as a 
tule, elongate the first season, and often not at all. 
EUPHORBIACEX. 
Jatropha podagrica, Hook.— Leaves alternate, petiolate, stipu- 
late, peltate at the base, shallowly 3-5-lobed, glabrous; petiole 
terete, sligntly and very gradually thickened at the base, glabrous. 
Stipules inserted at the very base of the petiole and partly on 
the stem, much branched, and fleshy, with terete pale green 
branches, tipped with deeper green glands, ultimately woody, 
spiny, and persisting on the short, stout, fleshy stems long after 
the leaves have fallen. Their function in their later stages is 
evidently meant to afford some protection against animals. The 
‘pecies is a native of Santa Martha, and would appear to be 
subject to periods of prolonged drought judging from the fleshy 
character of the stem. 
Phyllanthus montanus, Sw.— Leaves alternate, distichous, small, 
bract-like, subulate, acuminate, sessile, deep brown, dry, mem- 
prous, persistent. They are inserted on the edges of somewhat 
attened branches and also at much shorter intervals upon the 
edges of linear-lanceolate, deep green, and shining branchlets,

and thin for branchlets, but are leathery with numerous
