The genera of Leguminosae-Caesalpinioideae & Swartzieae

L. Watson and M.J. Dallwitz

Paloveopsis Cowan

Type species: P. emarginata Cowan.

Habit and leaf form. Trees (to 11 m); unarmed.

The leaves ostensibly ostensibly simple (unifoliate, apically obtuse-emarginate). Stipules absent or early caducous or very inconspicuous in mature leaves (about 9 mm long, deciduous); not connate.

Inflorescence and floral morphology. The inflorescences axillary and terminal; probably unbranched; short simple racemes. The flowers not distichous. Bracts minute, caducous, absent at anthesis. Bracteoles present; small, not enclosing the flower buds; persistent beyond anthesis; not valvate; connate (5 mm long).

The flowers showy; hermaphrodite; not pentamerous throughout; departing from pentamery in the androecium. Floral tube length relative to total hypanthium + calyx length 0.33. Hypanthium present; funnel-shaped. Calyx 5; covering the rest of the flower in bud; more or less regular; members imbricate. Corolla present; regular to slightly irregular (the petals subequal); 5; without greatly reduced members; polypetalous. Petals linear-lanceolate, sessile; imbricate; imbricate-ascending. The androecium comprising 9 members; with united members (connate unequally basally); members markedly unequal; including staminodia. The staminodia 6; shorter than the fertile stamens, subulate and hairy. Fertile stamens 3. Anthers attached well above the base of the connective (dorsifixed, versatile); dehiscing longitudinally. Ovary stipitate (stipe 1.5 mm); eccentric, with the stipe adnate. Stigma not dilated (capitellate, exserted).

Transverse section of lamina. Mesophyll secretory cavities (gland-dots) common.

Species number and distribution. 1 species (P. emarginata). Northeastern South America.

Tribe. Detarieae.

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, distributions of character states within any set of taxa, geographical distribution, and classification. See also Guidelines for using data taken from Web publications.
