I am new to aroids so I don't have much to report on these at this time.
Phil's observations are correct in as far as they go and he was able to
see. In the interior, the best part of GUAM, we get some REALLY large
leafed Alocasia macrorhysa (sp?) (A. macrorhiza (L.) Schott) that grow
upwards of 1.5 meters (don't know if .5 m increase rates a REALLY large
or not but they seem really big.
Here is Stones list of the more common Araceae in Guam
Anthurium
Pistia
Caladium bicolor
Colocasia esulenta
Cyrtosperma chamissonis
Alocasia macrorrhiza
Raphidophora aura
Typhonium
Monstera
Dieffenbachia picta
Xanthosoma
Aglaonema
Scindapsus
Not very interesting or unique from my limited understanding.
There is one Raphidophora species reported by Stone, 1962, that was seen
only once (Holotype) located in the MOST inaccessible site (former NUC
storage facility-even thought the Marine Guards are gone (meaning no
nucs) they still won't let you in without a REAL good reason.
Here is the description for those interested (from Micronesica Vol. 6
July 1970)
A high-climbing vine; leaves green, the petioles to 12 cm long, the
sheath open along lowest 4/5 to 5/6; blades lanceolate or narrowly
oblong, about 30 x 7 cm; acuminate-acute; spateh broad, thick, pale
yellow; spadix without appendix; flowers bisexual; carpels single,
separable, each with tow sthort staminodes; stigma capitate-discoid.
Guam: Naval Magazine near Maulap Stream. 28 April 1962. Stone 4101
(GUAM) Holotype. Seen only once.
Well, I have taken up enough space.
bye from GUAM, Where America's Aroiding DAY BEGINS!
