Subject: Re: [Aroid-l] Anthurium ID
Dear Steve:
While I still consider A. balaoanum a
distinct species it may prove to be merely an ecotype of A.
dolichostachyum. I know it only from the drier parts of Ecuador and it
is a much smaller plant with longer, more slender internodes and thinner
leaves as well as a smaller, thinner spadix with a very ephemeral
spathe. However, no feature is qualatively different from A.
dolichostachyum so perhaps the latter species simply has a wide
ecological and altitudinal range.
Tom
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 weakly raised.
Dear
Steve,
Aloha.
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
diagnostic.
Aloha,
Leland
