CATE Araceae, 17 Dec 2011.


Anthurium chamberlainii is endemic to Venezuela, known only from the State of Merida at 1500-1800 m but specific localities for the species are as yet unknown so the life zones (Holdridge, 1971) are undetermined. Most assuredly however the species occurs in some type of Premontane forest or Montane forest life zones since members of section Belolonchium nearly all occur at high elevations in wet forest.

General Description

Stems to less than 1 m long; internodes short, to 4 cm diam.; cataphylls to 20 cm long, persisting as a network of reddish brown  fibers; petioles 150 cm long, erect-spreading, subterete, unribbed, smooth geniculum 6 cm long, slightly thicker than petiole, tinged conspicuously with red; blade ovate-triangular-sagittate, 95 cm long, 70 cm wide, 1.4 times longer than wide, dark green and semiglossy above, moderately paler and semiglossy below, short-acuminate at apex, deeply lobed at base; margin broadly undulate more or less throughout; anterior lobe weakly concave and broadly convex along margins; posterior lobes 22 cm long, 25 cm wide, directed inward and held somewhat erect in live condition; sinus hippocrepiform, 11 cm deep, 18 cm wide, closed and subreniform when closed, more or less rounded at apex; major veins narrowly rounded, unribbed, moderately paler than the surface; basal veins 9-10 pairs, 1st pair free to the base, 2nd pair fused 5.5  cm, 3rd pair fused 8-8.5 cm, 4th pair fused 12-12.5 cm, 6th & 7th and higher order pairs fused 15 cm, 8th & 9th fused to 16-17.5 cm; posterior rib weakly moderately curved, especially toward the apex 17.5 cm long, naked along the sinus for most of its length, to 15 cm; primary lateral veins 7-8 pairs, arising at a 45-50° angle; collective veins arising from the 4th pair of basal veins, but weakly loop-connecting from 6th pair of basal veins, (2-)5-10 mm from margin; tertiary veins moderately obscure, weakly raised upon drying. INFLORESCENCE erect spreading; peduncle 60 cm long, 1.3 cm diam.; spathe 20-21 cm long, 10-11 cm wide when flattened, hooding, spreading forward at ca. 120° from peduncle, naviculiform, prominently attenuated at apex, reddish in bud, reddish violet except light greenish along margin at anthesis outside, reddish violet except thin, light greenish margin inside; spadix stipitate (stipe 12 mm long, 9 mm diam., whitish except pinkish at apex) 24.8-26 cm long, 3 cm diam. (drying to 1.8 cm diam.), oblong-fusiform, orangish red (drying reddish brown), directed mostly downward and an angle of 90°, gradually tapered to apex, narrowly rounded at apex; flowers 12-15 visible per spiral, 3.2-3.5 mm long, 1.8-2.1 mm wide; tepals drying medium reddish brown, matte, conspicuously granular; lateral tepals 1.8-2 mm, inner margin broadly rounded, outer margin 2-sided; stamens whitish, protruded at anthesis and persisting to ca. 3 mm above tepals; anthers 1.8-2 mm long, 0.6 mm wide; pollen yellow.
