baccate fruit, and an erect or annular disk not broadly attached to the calyx-tube ■ to this 
tribe I refer also JBursera, Balsamodendron, Santiria, and Canarium — to which latter 
Trig onochlamy s is most nearly allied, differing in its perianth and fruit.

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.

Hab. In sylvis vastis insula? Labuan, ad oram septentrioualem Borneo, Thos. Lobb. 
A plant of rather doubtful affinity, but which, from its close resemblance to Connarus, 
I have placed in the same natural family with that genus. It differs from the majority 
of ConuaracecB by the 5 stamens with apparently 1-locular anthers, and 3 ovaries, as alsc 
in the almost hypogynous insertion of the petals and stamens.
