4 Britton : Studies of West Indian plants 



The very young state of the inflorescence does not enable me 

 to give a description of the flowers of this interesting tree, and its 

 generic position is therefore uncertain. Its jointed and bracted 

 peduncle is similar to that of Dendropanax pendulum, but its 

 foliage is altogether different from that species. 



io. Dendropanax grande sp. nov. 



A tree up to 16 m. high. Leaves clustered at the ends of the 

 branches, ovate to ovate-elliptic, coriaceous in texture, rather 

 prominently pinnately veined, obtuse at both ends, the blade 15 

 cm. long or less, the stout petioles as long as the blades, or shorter; 

 peduncle much shorter than the leaves, erect, stout, about 4 cm. 

 long, bracted at the base; pedicels numerous, about 50, rather 

 stout, 2 cm. long; flowering calyx subhemispheric, 5 mm. broad; 

 petals lanceolate, about as long as the calyx; filaments rather 

 stout, somewhat longer than the petals.

11. Dendropanax blakeanum sp. nov. 



A slender tree about 8 m. high. Leaves clustered near the 

 ends of the branches, elliptic, or somewhat obovate-elliptic, rather 

 coriaceous in texture, faintly pinnately veined, sharply acute at 

 the apex, cuneate at the base, 10 cm. long or less; the petiole 

 one fifth to one third as long as the blade; peduncle erect, as 

 long as the leaves or twice as long, bracted at the base; umbels 8-16- 

 flowered; pedicels slender, 2 cm. long in fruit; flower buds ovoid- 

 hemispheric, obtuse, 3 mm. long just before the petals unfold; 

 calyx in young fruit turbinate, 4 mm. broad; fruit subglobose, 5 

 mm. in diameter; the conic persistent style 2.5 mm. long.

Differs from Dendropanax nutans in the longer, strictly erect, 

 few-flowered peduncles, and in the venation, texture, and shape 

 of the leaves. 



12. Dendropanax cordifolium sp. nov. 



A tree about 6 m. high. Leaves clustered at the ends of the 

 branches, chartaceous in texture, broadly ovate, prominently pin- 

 nately veined, obtuse, or short-acuminate at the apex, cordate, or 

 subcordate at the base, the blades 2 dm. long or less, about two 

 thirds as wide as long, the stout petioles about one half as long as
