Leland, your knowledge of aroids far outweighs my own but I
thought everyone who is an Anthurium enthusiast might like to
read some of Tom's notes taken from TROPICOS. Perhaps you can compare
these to your plant and determine if your specimen is truly Anthurium
balaoanum. For those unfamiliar, the numbers at the beginning are Dr.
Croat's specimen numbers. Tom once explained in a series of personal
emails that many people believe Anthurium balaoanum is Anthurium
guildingii. A. balaoanum is from Ecuador and Anthurium
guildingii is from the lower eastern Caribbean and as you know both plants
are very different.
#53706 Internodes short,
1.5-2 cm diam.; the roots ca. 5 mm diam., mostly directed downward; cataphyll
lanceolate, 3-4 cm long; petiole 3-sided, broadly and sharply sulcate adaxially,
sharply angular abaxially, the ridge usually markedly asperous; geniculum ca. 1
cm long; blades coriaceous, dark green, matte; the midrib narrow, obtuse, the
lateral veins obscure; the lower surface slightly paler; the midrib sharply
acute, prominently raised; the primary veins moderately obscure, slightly darker
than the surface; inflorescences erect; the peduncle terete, asperous, tinged
purple; spathe green, reflexed-spreading, moderately thin; spadix maroon turning
brown, the pollen whitish.
#50719 Epiphytic; stem
to ca 1 m long, internodes 1-1.5 cm long, 1-1.3 cm diameter; cataphylls
deciduous; petiole terete; sterile; flowered in cultivation, spathe absent,
spadix sessile, yellow-green, broadly arched, more or less tapered, stamens
exserted, pollen pale yellow.
#73144 Terrestrial; internodes
dark green; petioles obtusely flattened and weakly sulcate; blades subvelvety
and weakly glossy above, much paler and glossy below, midrib acute and
concolorous above, round-raised below; inflorescence erect; spathe green,
deciduous; spadix yellow-green, moderately glossy.
#90395 Stems elongated to 1 m long;
internodes short 2 cm diam.; petioles subterete, obtusely and weakly sulcate,
weakly glossy, weakly flattened toward base; blade thinly coriaceous, dark green
and matte-subvelvety above, slightly paler and weakly glossy below; midrib
narrowly raised, bluntly acute, slightly paler above, narrowly round-raised and
moderately paler below; primary lateral veins weakly paler, acute in shallow
valley above bluntly and narrowly raised, paler below; tertiary vein in part
My plant is past blooming this year, I
believe...but I will do so. I think my plant must be something other
than Anthurium balaoanum, if Dr. Croat's notes on the spadix are correct and
