tical with forms hitherto considered varieties of L. capitellata. On the other hand, 
there are various forms, otherwise differing from typical L. capitellata, but to 
a less extent, which agree with it in the nature of their stipules ; these are here 
retained in that species, except in the case of L. quadrinervia, where the venation 
is very different. Unfortunately, the stipules are deciduous, but can almost 
always be found at the apex, being apt to differ in size according to age.

to the species here called L. hispidissima, but distinguished by its smaller and 
less-veined stipules, more shortly acuminate leaves, and other characters.

Glomerulis staminiferis mediocriter pedunculatis, capitulis pistilliferis 
subsessilibus : foliis in specimine staminifero longiuscule in specimine 
pistillifero brevius petiolato, laminis rigide chartaceis, basi rotundatis,

Dioecious : staminate glomerules 6 to 7 mm in diameter, on peduncles 
4.5 to 8 mm long, the flowers bracteate, on pedicels attaining 2 mm in 
length, perianth deeply 5-parted, the segments oblong-lanceolate to ovate, 
1.2 to 1.5 mm long, acuminate; filaments 1.5 mm long, anthers 0.6 mm 
long; rudimentary ovary lanate: pistillate capitula subsessile, about 5 
mm in diameter; flowers sessile; perianth about 1 mm in diameter 
rather obscurely forming 4 or 5 lobes of which one is more distinct than 
the others; aehenes laterally compressed, obliquely ovate, about 1.5 mm 
long; stigma penicillate-capitate. 
Shrubs or small trees, 2 to 3 m high, the branches annulate, densely 
substrigose toward the apex, becoming glabrate : petioles of the staminate 
specimen 1.5 to 3 cm long, of the pistillate 6 mm or less, the lamina 
rigidly chartaeeous, inequilateral, ovate or elliptic-ovate, 7 to 10.5 cm 
long, 3 to 5 cm wide, the base rounded, the margins serrate or almost 
crenate, the teeth shallow, acute or apiculate, the apex shortly and 
acutely acuminate, upper surface scabrous, pilose or substrigose, the 
under pilose on the yellowish veins with gray tomentum in the interstices, 
trinerved with 3 to 5 additional primary veins, the nerves continuing
