286 USEFUL PLANTS OF GUAM. 
A variegated-leaved shrub quite common in gardens and often planted in rows 
near the houses, so as to receive the drippings from the thatched roofs. Leaves 
glabrous, petioled, opposite, ovate-lanceolate or broadly elliptic, narrowed at both ends, 
entire, usually variegated with white irregular patches, which frequently resemble a 
profile of the human face; flowers crimson, pedicelled, clustered in terminal thyrses, 
with very small, narrow, curved bracts and bracteoles, calyx small, sub-5-partite; 
segments equal, linear-lanceolate, corolla tube curved; limb 2-lipped, upper lip 
shortly 2-fid, lower 3-lobed; stamens 2, with 2 minute staminodes; anthers oblong, 
2-celled; cells parallel, without points; ovary with 4 ovules; style filiform, scarcely 
bifid; capsule oblong, hard, contracted into a long stalk; seeds usually 2, orbicular 
or subquadrate, flat, lacunose-rugose. 
This plant is probably a native of Java, but has been spread widely and is found 
in gardens in nearly all tropical countries. There are varieties having the leaves 
of a dark-claret color and other with green leaves. In some parts of India the 
natives use the leaves as soap.
