dense sessile terminal cyme, with 4 very short branches. Achene 
ovate-lenticular, 4 lin. long, the perianth-segments not more than 
half its length.— Central Madagascar, Baron 907! Nearly allied 
to P. tetraphylla, Blume. 
PILEA MACRODONTA, n. sp. 
Annua, dioica, caule subinermi elongato gracillimo, foliis oppositis 
longe petiolatis ovatis acuminatis grosse inciso-crenatis membranaceis, 
floribus utriusque sexus in glomerulos globosos axillares dispositis, peri- 
anthii masculi segmentis ovatis cuspidatis, achenio ovoideo-lenticulari 
piloso. 
An annual, with erect simple very slender unarmed stems a 
foot long. Leaves opposite; stipules persistent, ovate, brown, 
membranous, 4 in. long; petiole 1-2 in. long, very slender; blade 
2-3 in. long, broad, ovate, cuspidate, deeply inciso-crenate, very 
thin and membranous in texture, dark green, with a very few ob- 
scure pellucid bristles. Flowers of both sexes in globose clusters 
in the axils of many of the leaves. Male flower globose, under 
1 lin. in diam., with 4 stamens and 4 ovate cuspidate segments. 
Achene ovoid or obovoid, lenticular, obscurely pilose, under a line 
long, its perianth-segments irregular in shape and size, obtuse 
or cuspidate.—Shaded woods of the province of Imerina, Baron

P. hypnophila, Baker. | 
PILEA LONGIFOLIA, n. sp. 
Glabra, perennis, inermis, dioica, caule simplici elongato, foliis subses- 
silibus lanceolatis acuminatis argute serratis membranaceis, cymis glome- 
ratis axillaribus breviter pedunculatis, perianthii masculi segmentis 4 
oblongis, pedicellis flori zquilongis. 
A perennial herb, entirely destitute of hairs and stinging 
bristies, with long simple elongated erect stems. Leaves in 
distant pairs, nearly sessile, lanceolate, erecto-patent, 4-6 in. 
long, 3-1 in. broad at the middle, very acuminate, narrowed to 
the base, membranous, dark green, with close sharp regular 
erecto-patent teeth. Male flowers only seen, in small clusters 
from the axils of the leaves all down the branch on short slender 
ascending peduncles. Flower globos», 1 lin. in diam., with 4 ob- 
long glabrous segments. Stamens 4, the reduplicate flat filament 
longer than the oblong anther.— Central Madagascar, Baron 
1912! A well-marked very distinct species.
