FIG. 5. a. Distribution of M. froesii, M. venulosum, M. furcatum, M. jenmani, M. molle, 

 and M. flexuosum. b. Distribution of M. discolor. 



The relationship between this new species and M. venulosum is not excep- 

 tionally close but is probably the nearest which can be assumed from the availa- 

 ble evidence. The two species differ in the shape of the leaflet apices, the length 

 of the pedicels, the pubescence of the bracteoles, and the filament length and pu- 

 bescence.

Tall shrub with puberulous branchlets. Stipules 4 mm. long, caducous, subu- 

 late, acuminate, puberulous. Petioles 2-6.5 mm. long, canaliculate, puberulous. 

 Leaf blades oblong or oblong-lanceolate, 13-19-jugate, the pairs of leaflets 3-10 

 mm. apart. Leaflets 6-26 mm. long, 3-7 mm. wide, oblong, the base inequilateral, 

 the upper side more or less obtuse, the lower side acute, the apex truncate-ob- 

 tuse, retuse to emarginate, glabrous or sparsely puberulous at the base, some- 

 times generally pilosuiose on the lower surface; costa impressed or plane on the 

 upper surface, salient beneath, the venules obscure to prominulous. Inflorescences 

 2.5-4 cm. long, the axis puberulous, peduncles 1.5-5 mm. long; pedicels 2.5-3.5 

 mm. long, puberulous; bracteoles 7 mm. long, 3.5 mm. wide, elliptic, acute to acu- 

 minate, sparsely pilosuiose in the apical portion within, puberulous externally, 

 ciliolate. Hypanthium 1.5 mm. long, glabrous. Sepals four, 3 - 5—4 mm. long, 1-2 

 mm. wide, triangular-lanceolate, the adaxial one acute, the others caudate-acu- 

 minate, sparsely ciliolate. Petal claw about 3-5 mm. long, the complete blade not 

 seen. Filaments about 11 mm. long, villosulose near the base. Stigma capitellate. 

 Style about 8 mm. long. Ovary 4 mm. long, 1.5 mm. wide, oblong, finely puberulous 

 on one or both sutures, the lateral surfaces glabrous, the gynophore 2.5 mm. long, 

 minutely puberulous, inserted on base of the hypanthium. Fruit (immature to sub-
