551A87A8FFD6D203FF2557D1FE7587AD.taxon	discussion	Capparis trisonthiae is easily distinguished by its large (1.8 - 2.5 cm long, 1.3 - 2 cm wide) boatshaped sepals with ferruginous puberulous outside and puberulous in the marginal parts inside and its oblanceolate-spatulate petals (4.5 - 5 cm long, (1.6 -) 1.8 - 2.2 cm wide), long filaments (( 4 -) 4.8 - 5.5 cm), very short gynophore (2 - 2.5 mm) and ovary with shallow longitudinal grooves. Our new species resembles C. klossii Ridl., endemic to the Isthmus of Kra in southern Thailand, in leaf shape and texture (subcoriaceous to coriaceous, elliptic to broadly elliptic, with mucronulate or retuse apex and cordate base), the presence of 6 - 8 pairs of secondary veins, and its large ellipsoid fruit (7 - 10 cm long, 6 - 8 cm wide). The new species differs from C. klossii in its glabrous (vs more or less densely fulvous puberulous) leaves beneath, distinct (vs obscure) reticulation, and several floral characters, such as larger (vs 11 - 13 mm long, 6 - 7 mm wide) sepals, puberulous (vs glabrous) sepals in the marginal parts inside, much larger (vs 1.5 - 2 cm long, 0.75 - 1 cm wide) petals, more numerous (140 - 170 vs c. 55) stamens, very short (vs 4.25 - 5.5 cm long) gynophore, and the presence of shallow longitudinal grooves on the ovary.	en	Srisanga, Prachaya, Chayamarit, Kongkanda (2004): Capparis trisonthiae (Capparaceae), a new species from Thailand.
