The specimen from Chinaj was found in water in the axil of a large elephant-ear plant (Xanthosoma) by day in March.
A lateral bud is one situated on the side of a twig in the axil of a leaf-scar.
Rising out of the axil of each leaf are buds, of graduated size and development up to the open blossom.
In every bud examined which contained a flower, there was an axillary bud in the axil of the last, or next to the last, leaf.
The flower-scar is on the summit of the axis, and often apparently in the axil of a branch, as in Horsechestnut.
