tanum 1 it is somewhat gibbous, 4 in. long, 3 in. broad one way, 

 2 in. broad in the cross direction, is externally smooth and yel- 

 lowish, its outer envelope soft and of a subacid taste, 3 lines thick, 

 and is partly pressed into the sinuosities of the nut. This large 

 nut is osseous, with many crested irregular elevations, is 2-celled, 

 solid, with an osseous dissepiment 2 lines thick ; the cells 9 lines 

 broad, each filled by an oblong seed covered by a reddish mem- 

 branaceous integument, the kernel consisting of two large fleshy 

 cotyledons, which are edible and of a sweet flavour. In the Pari- 

 narium campestre, Aublet 2 , the fruit is much smaller, somewhat 

 gibbously oval, 1| in. long, f in. broad, having a smaller and 

 somewhat pointed nut marked by irregular prominences. This is 

 osseous, 2-celled, each cell containing one seed (the other some- 

 times abortive), with a reddish integument, the embryo white, 

 with two large fleshy cotyledons, edible, and of a pleasant flavour. 

 It has just been shown (ante, p. 335) that the smaller globose 

 1-celled fruit in the Parinarium of Bentham and of Hooker is 

 widely and generically different. 



Under Parinarium, Dr. Hooker likewise includes the several 

 Malayan species enumerated by Blume. These are : — 



* 



1. Parinarium scabrum, Hasskarl 3 , from Java. 



2. Parinarium glaberrimum, Benth. 4 , from Java. 



3. Parinarium Griffithianum, Benth. 5 (Exiteles multiflora, Korthals), 

 from Borneo. 



4. Parinarium Maranthes, Blume 6 (Exiteles corymbosa, Blume), from 

 Java. 



5. Parinarium sumatranum, Blume 7 , from Sumatra. 



Blume considered that his Parinarium sumatranum is identical 

 with the genus Petrocarya of Jack 8 (not of Schreber). In such 

 case all the five above-named species of Parinarium must be trans- 

 ferred to the genus of Petrocarya of Jack. In Jack's plant the 

 flower has 15 stamens, of which 8 are fertile and unilaterally 

 placed along the margin of an elevated ring, the other 7 ananthe- 

 rous stamens being seated consecutively along the rest of the same
