DESCRIPTIVE CATALOGUE. 861 
long-petioled, broadly ovate, shortly acuminate, quite entire, smooth on both sides; 
veins of young leaves puberulent at their axils on upper face, woolly on lower sur- 
face; terminal panicles corymbose, many-flowered; calyx short, cupuliform, sub- 
bilabiate, upper lip obscurely bidentate or entire, the lower distinctly acutely 
bidentate; corolla subequally 4-fid, equaling the calyx tube; leaf 12.5 cm. long, 
petiole 3.5 em. long; flowers small, calyx 2 mm. long, stamens 4, didynamous; limb 
of corolla reflexed, stamens and pistil slightly exserted; drupe small, surrounded 
below by the calyx. Type specimen collected by Gaudichaud in Guam. Leaves 
imperfect. The wood of the ahgao is hard and durable, but knotty and often crooked. 
It is much used in construction by the natives of Guam. It is very much like the 
molave, or molavin, of the Philippines ( Viter geniculata), a large forest tree belong- 
ing to the same family. Like many other Verbenaceae the ahgao has medicinal 
properties. In Guam its bark steeped in water is used as a remedy for neuralgia. 
The tree grows in rocky places, and sometimes yields logs 4 meters long by 45 cm. 
in diameter. Its inflorescence somewhat*resembles that of the elder.
