This endemic, monotypic genus is undoubtedly closely allied to Ganavalia, 
and even more closely to Dioclea, to the latter genus especially by its staminal 
characters, the fertile anthers being reduced to six. It seems; however, to be 
distinguished from Dioclea, as well as from Ganavalia, by its calyx characters. 
The probability of the plant representing a new genus was suggested to me by 
Doctor Prain in January, 1906, to whom a duplicate of Borden’s specimen had 
been sent for identification. Regarding this specimen, Doctor Prain wrote as 
follows : “I do not agree with you in thinking that it is a Dioclea. The leaf is 
wonderfully suggestive of Ganavalia, but I should not be surprised, when fruit 
is found, that you have near a new genus. It should be in the neighborhood of 
Dioclea and Ganavalia.” The fruit is as yet unknown.

1. Macropsychanthus mindanaensis sp. nov. 
Frutei scandens, glabra vel subglabra ; foliis trifoliolatis, f oliolis ovato- 
elliptieis, subglabris, yalde aeiuninatis; stipulis basi productis; racemis 
elongatis, multifloris ; floribus albido-purpureis, circiter 3 cm longis, 
vexillis basi auriculatis ; staminibus omnibus fertilibus; leguminibus 18 
cm longis, 5 cm latis, pubescentibns. 
A woody vine reaching a height of 10 m, nearly glabrous. Stems 
grayish, glabrous, terete, lentieellate, the shoots also glabrous. Petioles 
12 to 15 cm long, slightly hairy or ultimately glabrous, each subtended 
by a pair of pubescent stipules which are attached by their central part, 
the lower part produced at nearly right angles from the upper, both free 
parts less than 5 mm long. Leaflets ovate-elliptic, chartaceons, some- 
what shining when dry, of the same color on both surfaces, glabrous, or 
the lower surface with a few scattered hairs especially on the midrib and 
nerves, 10 to 15 cm long, 6 to 10 cm wide, base rounded or acute, the 
apex abruptly and rather slenderly acuminate ; nerves 8 to 10 on each side 
of the midrib, prominent ; petiolules pubescent, 5 to 8 mm long ; stipels 
acicular, pubescent, nearly as long as the petiolules. Racemes up to 40 
cm in length, glabrous below, above, at least when young, ferruginous- 
pubescent, flower-bearing in the upper half, the nodes produced as club- 
shaped branchlets which become stout and woody in fruit and nearly 
1 cm long, each bearing several flowers, and each subtended by a linear- 
lanceolate, deciduous, acuminate, 5 mm long, pubescent bract. Flowers 
about 3 cm long, pale-purple. Calyx 1.5 cm long, pubescent externally, 
villous within, the lower three teeth oblong-ovate, 8 mm long, 4 mm wide, 
blunt, the upper two connate into a 5 mm long and 7 mm wide lobe
