7. P. sublucens, Wedd. in DC. Prodr. xvi. i. 130. A glabrous 
dicecious herb. Stem erect from a creeping decumbent base, 6 in. 
to 1} ft. high, laxly branched ; branches ascending or erect, remotely 
leaved below, more densely so above. Leaves of a pair more or less 
unequal, ovate, sometimes with a trapeziform base, apex acuminate, 
margin crenate-serrate, serratures apiculate, 3-nerved, the lateral 
nerves passing beyond the middle, $-24 in. long, 4-1} in. wide or 
sometimes smaller, thinly membranous when dry, cystoliths when 
present linear, sometimes numerous especially on the upper face ; 
petiole slender, shorter or sometimes longer than the leaf. Stipules 
small, ovate-triangular, deciduous. Inflorescence (female) opposite, 
axillary, sometimes apparently paired in the leaf-axils, laxly pani- 
culate, 3-13 in. long or less, peduncle about half the length, slender 
as are also the few branches; cymules forming the short densely 
flowered ultimate branchlets. Achene compressed-ovate, narrowly 
winged, about 4 lin. long, brown, the persistent median perianth- 
segment oblong, rather broadly keeled, enveloping it to about the 
middle; lateral perianth-segments inconspicuous. Pedicel ulti- 
mately exceeding the achene in length.—P. Preuss, Engl. in Engl.

1 in.-long tip, 1-1} in. wide, at first sparsely hairy on the nerves but 
soon becoming glabrous ; petiole slender, shortly hairy above, one- 
third the length of the leaf, reaching 1 in. in the larger leaves. Sti-
