Note

TYPE: Panama, Croat 26166 (MO-2205213, holo- type; K, PMA, US, isotypes).
|

Description
|
Lianas, leafless near the ground; stems terete to 3-sided when young, the older stems terete or more commonly deeply 3-sulcate, in age the stem becoming so deeply sulcate as to cause the 3 terete segments to become nearly free; wood simple. Leaves pinnately 5-foliolate, nearly glabrous; petioles narrowly winged especially toward the apex, 3.5-7 cm long; rachis narrowly winged, the petiole and rachis pubescent on the midrib and scabridulous on margins of the wings; leaflets narrowly ovate, narrowly elliptic or oblanceolate, mostly long-acuminate, rarely obtuse at the apex, attenuate to obtuse at the base, 5-16 cm long, 1.5-5.5 cm wide, entire or remotely crenate-serrate with glandular teeth, glabrous above except for the midrib, glabrous beneath except for the densely barbulate vein axils, the margins scabridulous; stipules linear-lanceolate, 3-6 mm long, pubescent,

deciduous. Inflorescences borne on stout tubercles arising from the central cortex, the thyrses usually long, slender, clustered but few, mostly simple, rarely branched, appressed-puberulent to tomentulose, viscidulous, to ca. 15 cm long; pedicels appressed-pubescent, to 2.5 mm long, articulate below the middle. Flowers white; outer sepals appressed-puberulent, rounded, to 2 mm long, the inner sepals obovate, inconspicuously short-puberulent; petals obovate, to 2.8 mm long, the anterior scales 2/3 as long as the petals, the lower part as broad as long, long-ciliate, conspicuously pubescent on the inner surface, glabrous on the outer surface, the crest short-obovate, truncate to emarginate, pale orange, the deflexed appendages densely villous near the inner margins; disc glands 2, acute, densely villous throughout, the lateral scales consisting of a simple fold, the crest simple; stami- nate flowers with the stamens to 2 mm long, the filaments densely villous through- out, the pistil minute, densely pubescent at the apex. Fruits obovoid, beaked at the apex, gradually tapered toward the basal stipe, ca. 2.5 cm long, red, without wings, appressed-pubescent to glabrate, 3-locular, 2- or 3-seeded, the stipe ca. 5 mm long; seeds ovoid, 7-8 mm diam., pubescent, white-arillate at the base. The species is named for Thomas S. Elias, one of several recent collectors. It is recognized by its 5-foliolate leaves with narrowly winged petioles and rachises, sharp glandular-toothed leaflets, slender, mostly unbranched, glomerulate in- florescences borne on the older stems, and turbinate, wingless fruits. Also of diag- nostic value are the deeply 3-sulcate stems with simple wood.

Flowering occurs from June through September. Fruits develop to mature size by November and mature during the dry season from December to March. Paullinia eliasii is known only from Panama in tropical wet forest and premon- tane rain forest.
