ends, coarsely crenated ; cymes axillary and terminal ; calyx 

 nearly equal in length to the tube of the corolla ; calycine seg- 

 ments lanceolate, acuminated, subserrated ; lobes of corolla 

 quite entire. %. . S. Native of Guiana and the Antilles. Bes-

 Smith, exot. bot. 1. t. 54. Besleria melissse Tragi folio, Plum, 

 gen. p. 29. t. 5. icon. t. 48. Corolla purple. Capsule globose, 

 size of a large pea, and, without doubt, 2-valved, but probably 

 baccate from the umbilical funicles being long and fleshy. Seeds 

 as in E. reptans. 



Balm-leaved Episcia. Fl. July, Aug. Clt. 1789. Shrub 1 

 to 3 feet. 



4 E. ? PULCHE'LLA (Mart. 1. c.) stern erect ; leaves oblong- 

 ovate, wrinkled, crenated, running into the petioles, which are 

 connate ; cymes axillary ; calyx pentagonal, coloured ; lobes of 

 corolla entire : lower ones the largest. 1. S. Native of Tri- 

 nidad. Besleria pulchella, Donn, hort. cant. p. 140. Sims, 

 bot. mag. 1146. Besleria umbellata, Herb. Banks. Bracteas 

 X, opposite, under the corymbs. Calyx scarlet ; segments ser- 

 rated. Corolla yellow, striped with red. This differs from the 

 other species of Episcia, in the calyx being tubular and 5- 

 toothed, and of a reddish colour. The rudiment of the fifth 

 stamen wanting. It is said to be nearly allied to Besleria liitea, 

 and B. cocc'mea, Lin. but is probably a species of Alloplectus. 



Neat Episcia. Fl. July, Aug. Clt. 1806. PI. 2 to 3 feet.

Tribe II. 



CYRTANDRA'CE^: (this tribe agrees with the genus Cyrttindra 

 in the characters given below.) Calyx inferior. Fruit capsu- 

 lar and baccate, superior. Seeds exalbuminous. 



SuUribe I. 



TRICHOSPORE.<E (the plants contained in this tribe agree with 

 the genus Mschynanthns, in the seeds being furnished with hairs 

 at ends.) Blum, bijdr. 779. Fruit capsular, siliquose. Seeds 

 pendulous, expanded at both ends, or only at the base or apex, 

 into a setaceous or membranous wing. 



XVII. TROMSDORFFIA (named in honour of J. B. 

 Tromsdorff, who has written various works on the use of many 

 plants, as well as analyzing their chemical parts.) Blum, bijdr. 

 p. 762. 



LIN. SYST. Didynamia, Angiospermia. Calyx tubular, 4-5- 

 cleft ; segments equal. Corolla funnel-shaped, widened up- 

 wards, with an unequal, somewhat bilabiate limb. Stamens 4, 

 2 of which only bear anthers ; anthers 2-celled, cohering ; cells 

 equal in their insertion. Stigma broad, somewhat bilamellate. 

 Capsule silique-formed, elongated, falsely 4-celled, 2-valved ; 

 lobes of the dissepiment, which is contrary, bearing the seeds on 

 the margins, which are revolute. Seeds minute, pendulous, ex- 

 panded at the base into a membranous wing. Erect or radicant 

 shrubs, with opposite or alternate, serrated leaves, and elon- 

 gated, axillary peduncles. This genus is nearly allied to Didy- 

 mocdrpus, from which it differs in the seeds being furnished 

 with a membranous wing at the base. 



I T. SPECIOSA (Blum, bijdr. p. 763.) stem erect ; leaves op- 

 posite, nearly equal, elliptic-oblong, acuminated, unequally 

 toothed, clothed with rough hairs above, downy beneath ; pe- 

 duncles crowded, bifid, or sometimes dichotomous ; flowers 

 diandrous. Ij . S. Native of Java, on the west side of the 

 island, on the banks of rivers. Flowers showy, having the tube 

 of a deep violet colour at bottom, and the throat sulphur-colour- 

 ed. Filaments 4, villous at top. 



Showy Tromsdorffia. Fl. Year. Shrub erect. 



2 T. ? ELONGA'TA (Blum, bijdr. p. 765.) stem climbing, radi- 

 cant ; leaves alternate, or the opposite one is very small, ellip- 

 tic, attenuated at both ends, doubly serrated, downy ; peduncles 

 solitary, very long, bearing a many-flowered umbel at top ; sta- 

 mens didynamous. fj . w . S. Native of the Moluccas. The 

 fruit has not been seen, but the structure of the ovarium and 

 ovula agree with those of the first species. 



Elongated Tromsdorfifia. Shrub climbing.

 mens 4, didynamous, exserted, usually with the rudiment of a 

 fifth; anthers at first conniving by pairs ; cells parallel. Stigma

 formed, 2-valved, falsely 4-celled. Seeds small, generally sca- 

 brous from papillae ending in a bristle-like tail at both ends.
