Kewensis has therefore replaced the * Rain-Tree' in Pithecolohium ; this, however, is 

 a step which in turn similarly mars the generic limits of tliat group since the poda 

 of Pithecolohium must 7iot he septate. The writer places the species with more con- 

 fidence in Enterololium owing to its possessing the septate pods characteristic of 

 that genus. The pulpy, in place of spongy at length indurated mesocarp, and the 

 shortly pedicelled in place of sessile florets, cannot, in view of the variability of 

 these characters within adjacent genera, be considered more than comparatively 

 trivial deviations from the hitherto recognised characters of Enterololium. The 

 writer is unable, both on academic and on practical grounds, to agree with the pro- 

 posal, made by some botanists, to amalgamate Calliandra, Pithecolohium, Enterolo- 

 lium and Alhizzia, 



68. Calliandra Benth. 



Shrubs or trees. Leaves bipinnate, with small or large leaflets. 

 Flowers in globose heads, polygamous, 5-merous. Calyx campanulate, 

 tootlied. Corolla funnel-shaped, deeply 5-cleft. Stamens indefinite, 

 monadelphous at the base, filaments filiform much exserted ; anthers 

 minute, not gland-crested. Ovary stalked, many-ovuled ; style filiform, 

 stigma minute capitate. Pod strap-shaped, sliglitly falcate, flat, rigidly 

 coriaceous, the valves dehisciug with elasticity, bordei-ed by much- 

 tliickened sutures, continuous witliin, nariowed gradually to a short 

 stalk. Species 80, mostly tropical American.

 cuneate at base, 6 in. long, 2 in. wide and with an odd similar but 

 much smaller leaflet 1*5-2 in. long, •5-* 75 in. wide, on the outer side 

 below ; leaflets all glabrous on both sides, rather distinctly nerved 

 beneath and each with a gland on rachis at base. Flowers sessile iu 

 stnall dense globose heads '4 in. across, with minute bracts, on short 

 ascending slender peduncles •4-5 in. long, usually several together

There are no Malayan specimens at Calcutta j Mr. Baker, however, alludes to 

 the existence of Penang examples.
