the real affinity of Diccelia must be traced out, notwithstanding 

 the difference in the number of ovules, which place it technically 

 in a different tribe. 



Payeria of Baillon proves to be Quivisia, Cav., described from 

 far advanced specimens, the anthers having fallen away from the 

 staminal tube, or having been perhaps overlooked. 



5. GrALEAKIEiE. 



I have here grouped together four genera which partake of the 

 characters both of Phyllanthese and Crotoneae, but cannot be 

 strictly referred to either tribe. They may not really have much 

 affinity with each other ; but all are as it were intermediate 

 between the two great tribes, having the stamens of the outer or 

 single series opposite the sepals as in Phyllantheas, with the 

 uniovulate cells of Crotonese. All have simple undivided penni- 

 veined leaves ; and all have small calyces with imbricate teeth • 

 lobes, or segments ; and all have definite stamens round a central 

 rudimentary pistil; but in other respects they differ considerably. 

 1. Galearia, about 12 Malayan species, has simple terminal 

 slender racemes, curiously shaped almost valvate petals, much 

 longer than the calyx, the ovules and seeds much broader than 

 long, with a lateral micropyle and a small, broad, indehiscent, 

 drupaceous fruit. 2. Microdesmis, With one or two tropical 

 African and one or two tropical Asiatic species, has the flowers 

 clustered in the axils, the petals much longer than the calyx, as 

 in Galearia, but of a normal shape and imbricate, the ovules and 

 seeds normally shaped, the fruit a small indehiscent globular 

 drupe. Pentabrachion, a single tropical African species, does 

 not appear to me to be generically distinct from Microdesmis ; 

 but the specimens are incomplete. 3. PogonopJiora, one tropical 

 American species, has axillary, slender, paniculately branched 

 racemes, petals much longer than the calyx, and the capsule 

 separating into three 2-valved cocci. 4. TetrorcTiidium, of three 

 or four tropical American species, is apetalous, the racemes 

 axillary, sometimes branched, and the fruit separates into cocci. 

 The small calyx, and the anthers opening in four valves like those 

 of Endospermum, had induced its being placed amongst Hippo- 

 manese, from which, however, the position of the stamens and 

 the rudimentary pistil w r ould remove it. Altogether the place 

 of the genus is as yet very uncertain. Mueller described three 

 species in the * Prodromus :' a fourth is added in the ' Flora
