MEZONEURUM Desfontaines 

 MEZONEURUM PLATYCARPUM sp. nov. § Eumezoneurum. 



Frutex scandens, aculeatus, partibus junioribus subtus folio- 

 lis inflorescentiisque plus minusve brunneo-puberulis vel pubes- 

 centibus; foliolis alternis, subcoriaceis, usque ad 4.5 cm longis, 

 oblongo-ellipticis ad obovatis, apice late rotundatis vel subtrun- 

 catis, basi inaequilateralibus ; floribus circiter 15 mm longis, 

 extus dense cinereo- vel griseo-puberulis, calycis tubo valde obli- 

 quis, gibbosis ; petalis valde inaequalibus ; fructibus inaequilater- 

 aliter oblongo-obovoideis, circiter 12 cm longis et 5.5 cm latis, 

 glabris, nitidis, seminibus circiter 5. 



A scandent aculeate shrub, the younger parts, lower surface of 

 the leaflets, and the inflorescence brownish- or griseous- 

 puberulent. Leaves apparently large, bipinnate, the rachis with 

 retrorse spines. Leaflets numerous, alternate, subcoriaceous, ob- 

 long-elliptic to obovate, 2 to 4.5 cm long, 1.2 to 3 cm wide, apex 

 broadly rounded or subtruncate, the midrib forming sometimes 

 a very short apiculus, base usually distinctly inequilateral, 

 rounded or slightly cordate, the lamina on one side extending 

 farther along the petiolule than on the other, the upper surface 

 glabrous, shining, nearly black when dry, the lower puberulent ; 

 lateral nerves 7 to 9 pairs, rather slender, anastomosing, scarcely 

 more distinct than are the secondary ones and the primary reti- 

 culations ; petiolules about 2 mm long. Flowers numerous, some- 

 what crowded on the racemelike branches of the inflorescence, 

 their pedicels pubescent, about 10 mm long, the flowers about 15 

 mm long. Calyx-tube very oblique, gibbous, 4 to 5 mm long, 

 externally densely puberulent, about 7 mm in diameter, the lobes 

 very unequal, the larger one broadly obovate, rounded, puberu- 

 lent, concave, about 7 mm long and 6 mm wide, two lateral ones 

 about 5 mm long and 3.5 mm wide, elliptic-ovate, rounded, the 

 remaining two suborbicular, 4 to 5 mm in diameter. Petals very 

 unequal, one about 10 mm long and 8 mm wide, glabrous, prom- 

 inently two-lobed, when spread about 8 mm wide, the lobes some-
