90 PHANEROGAM I A. 



length, and an inch or less in breadth, entire or sometimes obscurely 

 repand; in the specimen from Ovolau, broader and mostly oblong- 

 ovate, 81 to 6 inches long and li to 2 J wide, the larger ones obso- 

 letely repand-toothed ; all more or less acuminate, loosely pinnately 

 veined. Petioles half or three-quarters of an inch in length. Sti- 

 pules very minute, squamaceous, triangular, caducous. Inflorescence 

 from the axils of the upper leaves, and terminal, minutely tomentose- 

 pubescent; the flowers numerous, in compound and paniculate, or 

 occasionally simple racemes, which in var. a. often exceed the leaves, 

 but in f3. (in which, however, the flowering is less advanced) are much 

 shorter. Peduncles and pedicels slender ; the latter 3 or 4 lines long, 

 recurved or drooping, subtended by a minute scale-like bract, and 

 furnished with 2 or 3 mostly alternate bractlets resembling the bract, 

 articulated a little below the flower and above the uppermost bractlet. 

 Calyx small, about one-quarter of the length of the larger petal, deci- 

 duous after flowering, of 5 distinct sepals: these are imbricated in 

 aestivation, not apjpendaged at the base, greenish, ovate or oblong-ovate, 

 pubescent-ciliate, somewhat unequal ; the two lateral, which are exte- 

 rior in the bud, being a little shorter than the others. Corolla hypo- 

 gynous, of 5 erect and unequal (greenish white) petals, obliquely imbri- 

 cated in aestivation, namely with one (of the two posterior) exterior, 

 and one (the anterior and saccate one) interior^ in the manner of 

 Viola, lonidium, &c. All the petals are obscurely ciliate, and not 

 unguiculate; the two posterior linear-oblong, with their tips somewhat 

 spreading; the two lateral similar to the posterior in shape, but a little 

 larger, and with the margins inclined to be involute about the middle; 

 the anterior one larger, and one-third longer than the lateral, hairy 

 inside below the middle, labeliiform orpanduriform; the upper portion, 

 or true lamina, obovate-spatidate, slightly emarginate, involute in the 

 bud, continuing to be involute from the middle to near the base, 

 which is abruptly dilated and gibbous-saccate, the sac-like projection 

 hemispherical externally. Stamens 5, hypogynous; the short fila- 

 ments very broad and dilated, shorter than the anthers, diadelphous, 

 namely, all but the posterior one united by their edges into an imper- 

 fect ring or cup; the two lateral ones inappendiculate and nearly 

 smooth externally, the two anterior pubescent externally, and each 

 thickened on the bach by an adnate, large and fleshy gland or tubercle : 

 filament of the posterior stamen resembling the lateral ones, but rather 

 narrower, smooth, and not appendiculate on the back, distinct, or con-
