For this period, 1,694 specimens were submitted for identification and/or name verification. Added to the herbarium collection during this period were 36 mounted specimens (total of 7,115). Some of the samples processed are described below:
Aleurites moluccana (L.) Willd., Euphorbiaceae. candlenut tree: Tree to 20 m tall, twigs stout, densely stellate-scurfy pubescent. Leaves alternate; petioles rather stout bearing two glands at their apex and mostly as long as or longer than blades; blades various, ovate to suborbicular, sharply 3- to 5-lobed or entire, 8-25 cm long, subtruncate at base, acuminate at apex, stellate pubescent on lower surface. Inflorescence in terminal panicles, cymulose, many-flowered, 8-15 cm long, scurfy-stellate. Flowers unisexual; calyx nearly globular, splitting into 2 or 3 lobes; petals narrowly oblanceolate, obtuse, white or cream colored, about 8 mm long. Staminate flowers numerous, pedicellate, with 15 to 20 stamens. Pistillate flowers few, sessile, preceding the staminate flowers, mostly solitary in the forks of the cymules. Fruit subglobose, 4-6 cm thick, a little wider than long, fleshy, greenish, indehiscent; seeds 1 to 3. Cultivated in China and Philippine Islands for the seeds, which yield valuable drying oil, elsewhere for shade. Naturalized in the tropics. Native to southeast Asia. Dade County (B94-408, G. W. DeChirico). (Correll and Correll 1982; Bailey Hortorium 1976).
Alstonia scholaris (L.) R. Br., Apocynaceae, devil tree, pali-mari, scholar tree: Tree to 20 m tall. Leaves whorled, to 20 cm long, oblanceolate, apex usually obtuse, thick and leathery, with veins in 50 pairs perpendicular to midrib; petioles to 1.25 cm long.

Fruits paired, pod-like, elongate follicles*, to 60 cm long and 0.3 cm wide, pendent. Grown as an ornamental in many countries. The very bitter bark is the source of an antimalarial drug and as a vermifuge. Where the tree is native, the white, fine-grained, lightweight wood is used to make slates for schools. Its natural range from India to Indonesia, tropical Australia, and Africa. Dade County (B94-528, G. W. DeChirico). (Huxley 1992; Mabberley 1989; Neal 1868).
