Mettenia Griseb. 



Examination of the male flower of IL glohosa Griseb. {Croton 

 (jlohosiim Sw. Prodr. 100 & Fl. Ind. Occ. 1181) confirms the opinion 

 of Bentham and Hooker (Gen. PI. iii. 32-1) that this genus Avhen 

 better known would have to be united with Thwaites's genus Chceto- 

 carpus. 



The male flower of M. glohosa has an irregularly 5-partite densely 

 2)uberulous calyx, and 6 to 7 stamens inserted at different levels on 

 a central column which is j^i'olonged above into a rudimentary 

 pistil. The anther-cells are attached separately to the connective 

 which is produced slightly beyond. There is an inconspicuous 4-lobed 

 disk below the stamens. 



As Bentham and Hooker suggest, there are two West Indian 

 species, one Jamaican originally described b}'' Swartz {Croton glo- 

 hosum), the other an undescribed Cuban species known only from a 

 fruiting specimen collected by Wright (no. 1973). Examination of 

 the material available has convinced us that the Cuban plant repre- 

 sents a distinct species, as shown b}^ the following comparison : — 



Ch^tocaepus globosus, comb. nov. 



Young twigs puberulous. Leaves roundish- ovate to roundish- 

 ellii:)tical, rounded or very obtuse at both ends. Capsule 11- 

 12 mm. 1. ; columella winged. Native of Jamaica. 



C. cubensis, sp. nov. 



Young twigs glabrous. Leaves elliptical with cuneate base. 

 Capsule 8-9 mm. 1. ; columella not winged. 



Frutex vel arhor (?) ramulis glabris. Folia 3-4-5 cm. 1., ellip- 

 tica aut anguste elliptica, apice rotundata vel obtusissima, basi cuneata, 

 glabra ; petiolus 2-3 mm. 1. Capsules 8-9 mm. 1. ; columella non 

 alata. Semina atra, hilo magno albo. Type in Herb. Mus. Brit, and 

 in Herb. Kew.

Dendeocousinsia Millspaugh. 



This genus was described in Field Columb. Mus. Bot. ii. 1913, 

 374, from specimens collected in Jamaica by Mr. William Harris and 

 Dr. N. L. Britton. The author remarks tliat it is " near Sehastiania,^^ 

 but does not indicate how it differs from that genus. Dr. Millspaugh
