114 SIR DIETRICH BRANDIS—AN ENUMERATION 
trace, which is in the bark in the upper fifth of the internodium, 
and two lateral ones, which run in the bark through the upper 
third of the internodium. Until more complete specimens of 
this most interesting tree are available, nothing can be said, 
except that is seems to stand nearest to Balanocarpus and 
Shorea.

(Including Dyerella, Heim.) 
Trees with thickly coriaceous shining leaves, which are gene- 
rally perfectly glabrous; in one species only, C. flavum, clothed 
beneath with fine tomentum of minute stellate hairs. Secondary 
nerves numerous, not very distinct. Flowers in racemose 
panicles. On the edge of the broad receptacle 5 narrow valvate 
calyx-segments, tomentose on the outside, and often also on the 
inside. Stamens 15; anthers oblong or linear, mostly hispid ; 
valves more or less unequal; connective with a short mucro. 
Ovary free; style filiform or cylindric, longer than ovary. 
Fruit globose, free; segments of fruiting-calyx unequal; two 
large wings, the three others smaller. Radicle short, thick ; coty- 
ledons divided into numerous lobes. So far as known, starch 
is the chief non-nitrogenous substance stored in the cotyledons. 
Pierre, in tab. 255 H, gives a representation of the structure 
of internode and petiole of Cotylelobiwm Melanoxylon. I have 
had no material at my disposal for the anatomical examination of 
this genus.

Secondary nerves very numerous, connected by loops of promi- 
nent intramarginal veins. Anthers oblong, hispid; style filiform. 
Cotyledons divided into humerous lobes, attached to a short 
thick radicle. Cells filled with starch. These are all characters 
of Cotylelobium. Heim acknowledges that the flowers are those 
of the genus, but draws attention to the large and semipersistent 
bracts, which are minute and deciduous in the other species 
of Cotylelobium. The genus Dyerella he mainly bases upon the
