Type
Type in the herbarium of the New York Botanical Garden, collected on the bank of a stream in dense forest in El Umbo region, western part of the Department of Boyaca, Colombia, "2,500 ft.'' altitude, October 1, 1932, by A, E. Lawrance (No. 501). The type specimen of Pseuderanthemum chaponense f. lilacinum was collected from a plant "2-4 ft." high with stems up to "½ inch" in diameter. ]Mr. Lawrance states that it was "beautiful in the forest and similar to lilac.'' The label on Lawrance 441, the typical white-flowered form, states that the plant was 15-20 feet high, with stems up to an inch in diameter. These data are probably erroneous. The specimen indicates that the plant is subherbaceous, slender-stemmed, and probably only a meter high or less.
