General habit and inflorescence of the last. Branches, leaves below and calyx 

 densely finely grey-downy. Pinnm 12-24, distinctly stalked; leaflets sensitive, 

 ^ in. long. Baoemes close, copiously panicled ; pedicels erecto-patent, twice the 

 calyx. Flowers larger than in the last, bright yellow. Filaments densely woolly near 

 the base. Pod 3-4-seeded, 3-4 in. by 1 in. broad, without the wing.

Maiaoca, Griffith, Maingay. — Distrib. Malay isles. 



Branches thick, rather downy, armed with copious small falcate prickles. Leaves 

 a foot or more long ; pinnae and leaflets both 8-10, the latter obovate-oblong, rigidly 

 coriaceous, glabrous, obtuse, 2-3 in. long. Eacemes as long as the leaves, forked ; 

 rachis virgate, woody ; pedicels very short. Calyx glabrous, |— J in. long, the upper 

 teeth not more than ^ in. deep, the lowest rather longer, the tube splitting off at the 

 insertion of the glabrous filaments. P«iais little exserted, reddish-yellow, much nar- 

 rower than in the other species, per.'nanently imbricated, oblanceolate-spathulate. 

 Pod thin, 3-4 in. by 1 in., 3-4-Beeded, with a moderately broad wing. — The structure 

 of the flower is so different from that of the other species that it would probably be 

 better to separate it generically, and place it next to Wagatea, 



99. FTEROXiOBXUnX, B. Br. 



Woody climbers, with the habit of Ccesal^nia, from which they differ only 

 in pod. Calyx deeply cleft, with the disk near the base, the lobes imbricated, 

 the lowest longer and more hooded than the others. Petals spreading, oblong- 

 and clawed, equalling the calyx. Stamens 10, free, declinate, little exserted ; 

 anthers oblong, versatile. Ovary sessile, 1-ovuled ; style filiform, stigma small 

 terminal. Pod indehiscent, samaroid, with a large horny oblique terminal 

 wing. — DiSTElB, Species 4, spread through the Tropics of the old world.
