Iresine nigra, n. sp. 
Shrubs, sometimes shrubby trees, undergrowth in forests, 
turning black on drying, glabrous except among the flowers: 
leaves much as in the preceding but thicker, smaller and with 
longer petioles: inflorescence a lax panicle with very long, 
slender alternate branches loosely set with small spikelets, 
which are pedunculate only at the base of branches: flowers 
sometimes §, but apparently generally unisexual by failure of 
pollen or ovules to mature, some plants being prevailingly 
pistillate, others staminate: bracts and sepals in ¥ and $ flow- 
ers as in the preceding, but the flowers are smaller, 1.5" 
long; in those flowers which are more conspicuously stamin- 
ate the sepals are longer, narrowly oblong, somewhat pilose, 
but the woolly growth from the base is inconspicuous: utricle 
top-shaped, narrowed below into a stalk-like base and above 
into a short style with two long filiform stigmatic branches: 
staminodia very minute.

Iresine arbuscula, n. sp. | 
A small tree 4.5 to 6" high with large oblong-elliptical 
green leaves 14-21" long including petiole 3-4" pty 
branches and petioles black in dried specimens: inflorescenct 
a pedunculate naked drooping panicle at the ends of leafy 
branches, the larger branches of the panicle subtended by 
Scarious bracts, never by reduced leaves as in /. paniculale 
which it resembles considerably in inflorescence; branches ° 
inflorescence long, filiform, not divaricate: spikelets very 
small and closely set along the ultimate branchlets; rhachis 
short woolly, but pedicel of flower little hairy. The spect 
men examined seems to be staminate, although the utricle '8 
so largely developed as to possess papillate stigmatic branche 
S No apparent reason why seed shoul not | 
prominent, long and broad.
