A small tree. Leaves 2^1 in. , membranous, penninerved, more or less glaucous and 

 often reddish beneath; petiole as long, very slender; stipules |-1 in., lanceolate. 

 Racemes 1-4 in. Flowers -% in. diarn. Calyx-lobes 'unequal. Stamens 6, or 

 fewer. Capsule ^-3 in. diam., glaucous, didymous, tardily dehiscing. Seeds^IS\f. 

 enveloped in the aril. The only Indian specimen that I have seen is one sheet (9) ot 

 Wallich's Herbarium from Penang, under Stillingia sebifera. It may be introduced 

 into that island ; and yet so common a Malayan plant may be expected to occur in 

 British India. The Ceylon habitat is probably an erroneous one.

Trees and shrubs. Leaves alternate, entire, serrate or toothed, penni- 

 nerved ; petiole often 2-glandular at the top. Flowers in terminal simple 

 or panicled spikes or racemes, monoecious (always ?), apetalous ; males 

 several in each bract ; females in the lower part of the spike, or in separate 

 spikes, solitary in the bracts. Disk 0. MALE FL. Calyx membranous, 

 shortly 2-3-lobed or toothed, or split to the base into 2-3 valvate 

 sepals. Stamens 2-3, filaments free ; anther-cells ovoid, distinct, contiguous, 

 parallel. Pistillode 0. FBM. FL. Calyx 3-fid or -partite. Ovary 2-3- 

 celled ; styles free or connate at the base, spreading and recurved, undi- 

 vided, cells 1-ovuled. Capsule crustaceous, fleshy or pulpy, rarely woody, 

 at length loculicidally (not elastically) 3-valved. Seeds globose, estrophio- 

 late, usually long-persistent on the columella, testa crustaceous, albumen 

 fleshy ; cotyledons broad, flat. Species 25, all tropical.
