748 Hemsley. — On the Germs Cory no car pus, Forst . , 
position of the parts of the flower rather than in any funda- 
mental character. Both genera are pentamerous up to the 
gynaeceum, but the position of the fertile stamens and the 
drumstick-shaped staminodes of Pentaspadon is the reverse 
of what it is in Corynocarpus , and the continuous disk is 
io-lobed, instead of consisting of five free bodies. 
The oblique or unsymmetrical, imperfectly 2-celled 
gynaeceum of Corynocarpus is analogous to that of Cotinus 
as figured by Engler (op. cit. t. 12, Figs. 29, 30), where he 
represents an immature drupe, similar to Figures 23 and 24 in 
our plate (after Engler), but without any trace of a second 
cell. The gynaeceum of the genus Trichoscypha , Hook, f., 
has three styles, but the drupe is one-celled and one-seeded. 
Sometimes, however, a second cell is partially developed, 
as shown by Engler (op. cit. t. 11, Figs. 11 and 12), though 
without any trace of a second ovule. The fibrous endocarp 
of the fruit of Corynocarpus has a parallel in Mangifera , and 
the minute radicle of a large embryo is repeated in Bouea , 
Holigarna and other genera. 
The general aspect of Corynocarpus is so similar to that 
of Mangifera , and some species of Buchanania , that one 
would naturally, without examination, sort specimens into 
the Anacardiaceae, or perhaps into the Myrsinaceae. 
Anatomical Characters. 
Coming to the anatomy of Corynocarpus , it is true that 
there is a total absence of resin-ducts, and Engler lays great 
stress on this fact. He states (DC. Monogr. Phanerog. iv, 
p. 173) ‘Omnium Anacardiacearum rami atque ramuli in 
sectionibus transversalibus circulum phloemati interiori pro- 
prium canalium succum resinosum continentium extusque 
libri semicirculis circumdatorum, insuper stratum scleren- 
chymaticum hypodermatis exhibent.’ This being so, and 
I suppose no one could write on the subject with more 
authority than Engler, it seems almost a pity to admit an 
exception, yet as there is nothing that correlates with it, and
