baccate fruit, and an erect or annular disk not broadly attached to the calyx-tube : to this 

 tribe I refer also Bursera, Balsmnocleudron, Santiria, and Canar'mm — to which latter 

 Trigoiiochlamys is most nearly allied, differing in its perianth and fruit.

1. Triomma Malaccensis, H. f. 



Hab. In peninsula Malayana ad Malacca, beat. Griffith. 



In the structure of the fruit, Triomma resembles Bursera, to which it is very closely 

 allied; it differs in the 5-lobed calyx, in the broadly winged fruit, and remarkably in 

 habit.

1. Hemiandeina Bornensis, H. f. 



Hab. In sylvis vastis insulae Labuan, ad oram septentrionalem Borneo, Thos. Lobb. 

 A plant of rather doubtful affinity, but which, from its close resemblance to Counarus, 



I have placed in the same natural family with that genus. It differs from the majority 



of Connaracece by the 5 stamens with apparently 1-locular anthers, and 3 ovaries, as also 



in the almost hypogynous insertion of the petals and stamens. 



Tab. XXVIII. fig. 1. portion of peduncle, with pedicel, bracts, and flower; 2. petal; 3. stamen ; 4. 

 ovary; 5. young bicarpellary fruit ; 6. tricarpellary fruit; 7- vertical section of immature carpel : all 

 magnified.
