Brandzeia Baill.

Baithiaea filicifolia Drake

Type species: B. filicifolia Baill.

Habit and leaf form. Resinous, deciduous arbres; inermes.

Feuilles composées (the petiole with a cupular gland); pennées; paripennées. Folioles peu nombreuses sur chaque feuille (mostly 7–9); alternes; pétiolulées; avec des pétiolules pas notablement tordus; not gland dotted, elliptic to ovate or oblong, basally truncate to wedge shaped, symétriques ou presque à la base (only slightly unequal-sided); the leaflets pinnately veined; sans nervure marginale continue. Stipules absents ou rapidement caduques ou très rudimentaires (minute and caducous); ni foliacées ni épineuses. Stipelles absents.

Inflorescence and floral morphology. The inflorescences complex; inflorescences on year-old wood, dense and complex, comprising large, showy clusters of panicles and racemes with flowers opening simultaneously. Fleurs pas distiques. Bractéoles two, minute, at the base of the hypanthium.

Fleurs petites; hermaphrodites; flowers actinomorphic to slightly irregular (subactinimorphic); pas entièrement pentamères; se démarquant de la pentamérie dans le calice; colorées (sepals, corolla, staminal filaments and style all bright carmine pink). Longueur du tube floral relativement à la longueur de l'ensemble hypanthium plus calice, environ about 0.3. Hypanthe présent; floral tube long-tapered to the base, fairly long (about 7–9 mm); hypanthium more or less tubular. Perianth comprising distinct calyx and corolla. Calice présent; very gland dotted, 4 partite; undivided or only shortly lobed in the bud; ultimately polysépale; plus ou moins régulier (comprising two only slightly unequal pairs); imbriqué. Corolle présente; only légèrement zygomorphe; pétales 5; sans aucun pétale fortement réduit. Well developed petals 5. Corolle polypétale. Pétales all long onguiculés; imbriqués; supposedly imbriqués-ascendants (?); pink to rouge. Disque présent et visible. The androecium comprising 10 members; not declinate; androcée ayant ses éléments tous isolés les uns des autres; androcée long-exserted, ayant des éléments tous plus ou moins égaux en longueur (the slender filaments more or less equal); androcée sans staminodes. Étamines fertiles 10. Anthères versatile, attachés nettement au dessus de la base du connectif (the latter glandular); déhiscence introrse. Ovaire long stipité; libre. Le stigmate s'est non dilaté (or only very weakly so, the style slender, involute). Ovule(s) nombreux.

Fruit, seed and seedling. Fruit indéhiscent; droit (‘wavy’); pas cloisonné intérieurement; sans valves se tordant ni s'enroulant notablement; Acer-like, winged distally to the single seed (and with a submarginal ridge over the seed, which is located at the apex of the broad, thin wing, the latter tapering to the basal stipe); ne devenant pas ligneux (with a thick, leathery rind). Fruit sans nervures proéminentes ni en relief. Graines copiously endospermiques; pas arillées; avec un radicule droit ou légèrement oblique.

Transverse section of lamina. Cavités sécrétrices absentes du mésophylle.

Species number and distribution. 1 espèces (B. filicifolia). Western Madagascar.

Tribe. Cercideae.

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.
