the whole inner face. A small tree, on the banks of the Chocon and 

 the shore of Lake Yzabal. 



18. Casearea (Piparea) Brighami. A small tree with pubes- 

 cent branches : leaves oblong-oblanceolate, rather abruptly and nar- 

 rowly acuminate, narrowed to a very short petiole, entire, glabrous 

 and shining above, puberulent beneath, G to 10 inches long and 2 to 4 

 broad, thin-coriaceous, not punctate : flowers in dense axillary clus- 

 ters ; pedicels slender (3 to 6 lines long), jointed in the middle, pubes- 

 cent with spreading hairs below the joint, tomentose above : sepals 5, 

 ovate, 2 lines long (becoming 5 in fruit) : stamens 18, twice longer 

 than the inner whorl of linear villous staminodia : ovary pubescent ; 

 style trifid : fruit dry, triangular-obovate, 6 lines long, 1-few-seeded : 

 seed slightly villous. — At the Chocon plantation. 



19. PoLYGALA asperuloides, HBK. Near Yzabal. This spe- 

 cies can scarcely be referred to P. galioides, as is done by Bennett 

 and Hemsley. It resembles P. vertlcillata, but is perennial and with 

 broader leaves. P. galioides, of Guiana and Brazil, is an annual, 

 with smaller flowers in a much more slender elongated open spike, 

 and much smaller capsules and seeds. 



20. Drymaria cordata, Willd. In wet places on the shore of 

 Lake Yzabal. 



21. Clusia ? A large tree in the Chocon forests; only 



pistillate specimens collected. Glabrous ; leaves coriaceous, opposite, 

 oblanceolate, obtuse, narrowed to a stout petiole {h inch long or more), 

 4 or 5 inches long : flowers solitary and terminal on a bibracteate 

 peduncle, the broadly ovate segments of the perianth decussate in 

 pairs, the petals 5 lines long: immature capsule oblong (15 lines 

 long), Gvalvate ; the stigmas broad and peltate upon short and very 

 thick styles. 



22. Clusia ? A low wide-branching tree, in a potrero at 



Yzabal ; called a gutta-percha tree. Leaves opposite, thick-coriaceous, 

 oblong-obovate, very obtuse, attenuate to a stout petiole (an inch long), 

 6 or 7 inches long : peduncle axillary, short, bearing a few flowers 

 upon stout bracteate pedicels : segments of the perianth decussate in 

 pairs, rounded ; fertile flowers with 4 stamens ; ovary 6-valved and 

 bearing 6 broad peltate sessile stigmas. 



23. Symphonia globulifera, Linn. f. (Moronobea coccinea of 

 Grisebach ; the hog-gum tree of Jamaica.) Leaves unusually short 

 and narrow (2 or 2^ inches long and 5 or 6 lines broad) ; immature 

 fruit oblong-ovate, beaked by the stout style, by abortion 2-celled and 

 2-seeded. A large tree in the Chocon forests.
