 PI. XIX, figs. 19—21; PL XX, figs. 4 a, b. 



Endocarp lanceolate slightly curved above, thick crustaceous, dividing lengthways 

 into 2 valves in germination, rugose with irregular longitudinal channels and ridges; 

 walls of uniform thickness, with short straight canals at the base and apex. Seed filling 

 the long cavity, orthotropous; testa adhering to the endocarp; micropyle conspicuous, 

 inserted into the apical canal of the endocarp. 



Length 33 mm., breadth 1.3 mm. Reuver. 



With this open endocarp, showing the internal structure and the seed, were 

 found several specimens of these endocarps with the two valves united, and some of 

 them show remains of a fibrous mesocarp between the ridges. This justifies us in refer* 

 ring the specimens shown in figs. 20 and 21 to the same species, though they were found 

 at another locality. 



Endocarp lanceolate slightly curved at the tip, triangular, opening at the ventral 

 angle; covered externally by a thick coarsely *fibrous mesocarp which clothes the 

 whole carpel. 



Length 3.8 mm., breadth 1.5 + mm. Swalmen. 



With these fruits from Reuver and Swalmen we may perhaps associate a frag* 

 ment of rachis, (PI. XX, fig. 4) on which is impressed the shape of a complete fruit, 

 broadly ovate in shape and of about the size required. 



Length of fruit 5 mm., breadth 1.5 mm. Brunssum. 



ARACEAE. 



EPIPREMNUM CRASSUM Sp. nov. 

 PL IV, figs. 1—9. 



Semina parva, reniformia vel naviculiformia, parum lateraliter compressa; 

 testa crass1ssima durissimaojje. 



Seed reniform or boat*shaped, somewhat compressed but rounded laterally, 

 smooth or minutely granulate ; attachment long*oval sunk reaching to the micropyle, 

 which is surrounded by fine radiating striae ; testa very thick and hard. 



Length 2.5 mm., breadth 3 mm. Reuver, Swalmen. 



In a few specimens outer layers of cells are preserved. An outer skin is rarely 

 seen, it is black shining wrinkled large*celled finely striate transversely (i.e. at right* 

 angles to the curve of the seed). A second layer of large loose cells usually decays, but 

 occasionally shows as a coarse network on the surface of the hard testa. These two 

 layers belong to the fruit and may represent merely an exceptional hardening of parts 

 usually succulent. The testa is thicker and denser than that of E. pinnatum, which we 

 have figured for comparison (PI. IV, figs. 10—12); it is light*brown, polished externally
