CYRTOSPERMA. 151 
is flattened, by 3 elevated undulated crest-like lines. Tegument 
hard subcrustaceous. Albumen carnosum 
Embryo axilis longitudine albumenis curvatus, subclavatus, 
radicular end greenish marked along the convex side with a 
long slit, or rather line. 
Habitus Lasie; foliis hastatis, pedunculis armatis, aculeis 
conicis subrectis. , 
A Lasia discrepat. spatha per totam longitud. aperta, tota 
persistens. Perianth. foliolorum numero, structuram. Stamina 
que valde singularia. 
Placenta intrante, ovuleque anatropo. Semen embryo 
excepto omnino Menispermaceo. Common in ditches, Malacca, 
As the curved seed seems uncommon, or unnoticed in Aroi- 
деге this genus may be called Cyrtosperma. 
Seed sub-erect broadest diameter opposite the funicle, 
margin curved upwards, flattened emarginate, a toothed crest 
added in the centre, towards the cotyledonous end, micropyle 
sub-funnel-shaped, very conspicous, surrounded by a more or 
less toothed border, its inner margin lengthened and emar- 
ginate. Sides perpendicular convex; any one would think this 
had originated from a Sarpy liveopous ovule. 
The funicular face of the seed is posticous, the inner mem- 
brane of the seedis obsolete. I believe it covers the albumen, 
it certainly does line the micropyle, in the form of a thin 
membrane, the part doing so being no doubt the very dilated 
apex of the second tegument of ovule.
