ENUMERATION OF PHILIPPINE LEGUMINOSAE. 121 



which is retuse at the apex. Petals all clawed, and about equal in length; 

 standard with a 7 mm long claw, the lamina orbicular, retuse, 2.5 cm 

 wide, with two auricular callosities at the base. Stamens all fertile, the 

 vexillary filament free at the base, united above with the others. Ovary 

 densely villous. Pods (immature) about 18 cm long, 5 cm wide, rather 

 flat, not much thickened on the dorsal suture, ferruginous-pubescent, the 

 apex acuminate. Seeds 3 to 5. 



Mindanao, Province of Surigao, Bolster 330, with flowers and immature fruits, 

 April, May, 1906, in forests along streams at an altitude of about 60 m. 



Of the two species here described, the above approaches closest to the type 

 of the genus, Blacropsychanthns lauterbachii Harms, of New Guinea. It is, 

 however, quite distinct from that species. 



2. Macropsychanthus ferrugineus sp. nov. 



Frutex scandens, ramulis foliis inflorescentiisque ferrugineo-pubescen- 

 tibus; foliolis ovatis vel elliptico-ovatis, acuminatis, stipitellatis ; stipiilis 

 basi productis; lloribus 2.5 cm longis; stamiuibus omnibus fertilibus; 

 leguminibus usque ad 18 cm longis, 7 cm latis; seminibus 2.5 cm diametro, 

 liilo lineari semicinctis. 



A scandent woody vine reaching a height of at least 10 m, the stems 

 grayish-brown, terete, lenticellate, glabrous, the younger parts rather 

 strongly ferruginous-villous as are the petioles and leaflets. Leaves 

 very similar to those of Philippine Dioclca rfftexa; petiole about 15 cm 

 long, subtended by a pair of 1 to 1.5 cm long stipules attached by their 

 median portions, and about equally long above and below the point of 

 attachment; leaflets ovate to elliptic-ovate, subcoriaceous, 10 to 20 cm 

 long, 5 to 13 cm wide, ferruginous-villous on both surfaces; nerves 11 

 to 13 on each side of the midrib; petiolules about 5 mm long; stipels 

 acicular, villous, about as long as the petiolules. Eacemes 30 to 40 cm 

 long, ferruginous-pubescent, flower-bearing in the upper half, the nodes 

 produced as short, club-shaped branchlets, each bearing several flowers, 

 each node subtended by a lanceolate, deciduous, ferruginous bract about 

 7 mm long. Flowers 2,5 cm long, pink. Calyx 1.5 cm long, ferruginous- 

 pubescent outside, somewhat villous within, the- lower three teeth oblong- 

 ovate, about 7 mm long, 5 mm wide, the upper two connate into a 6 mm 

 long and wide lobe, cleft about one-third its length into divergent teeth. 

 Petals all clawed; standard 2.5 cm long, the claw stout, about 7 mm. long, 

 the lamina orbicular, 2 cm wide, retuse, not auricled at the base but 

 with a thickened swelling; wings equalling the standard, about 8 mm 

 wide, decurrent-acuminate at the base; keel as long as the other petals, 

 incurved, hooded, 1 cm wide (not spread), decurrent-acuminate at the base. 

 Staminal-tube curved, the filaments all antheriferous, the vexillary one 

 free at the base, somewhat united with the others above. Ovary villous. 

 Pod almost woody, turgid, 11 to 18 cm long, 6 to 7 cm wide, at first 

 ferruginous-pubescent, when very old glabrous or nearly so, nearly 1 cm 

 thick on the dorsal suture, at least 2 cm thick in the middle. Seeds
