Hi all,
I am Dany from Belgium
I am a collector of alocasia and i am searching other people who like me =
love this genera.
Here in Belgium,there is nobody and the major of the time,when you talk =
about this with somebody,the first reaction is something like'what is =
this animal' or other thing like that.So
really,there is nobody that is interesting about it.If there is someone =
who is really interesting with alocasia who learn this,is it possible to =
contact me for that we can exchange different avis about
this genera?(Please all,excuse me but i talk not a good english!)
I am searching also some people with who i can exchange source of =
plants,or maybe plants of that
genera.Of course, i like also other aroid(like =
anthurium,dieffenbachia,philodendron etc)but my
major interest is alocasia,and it's not easy because here in europe =
there is virtually no
species avalable exept the few that are commun.So the major of my =
collection is from corespondant in Australia and asia,and from some =
nurserys in Usa.Also some plants from Dewey Fisk and Dick
Mansell.So i am searching people from other country (usa,australia,new =
zeeland or other) with who
i can exchange plants and passion!
Thanks to reply me

Hello I am looking for two alocasias samar and putzeysii. I would love to
trade or buy these if any one has them. Also I am looking for any other rare
ones. THANKS

I'm an Araceae which it can be an Alocasia or an Colocasia. Someone can
tell me what's the difference between this two genus?

Dear Christophe,

Let me TRY to assist you with this technical one, since this is your second
plea to this list---I had hoped one of the 'big guns' out there would have
tackled this one, but here goes--

!) Both are closely related to each other. The most important difference
between the two is microscopic, and found within the female flowers. In
Colocasia the placentae are parietal (along the interior sides of the
gynoecium, which is the embrionic future berry) from top to bottom, and the
many funicules ('stems'?) of the ovaries attach to the placentae along the
interior sides of the ovary.
In Alocasia the placenta is basal, and the sparser number of
funicules/ovaries are attached to this placenta within the gynoecium, but
along its interior base.

2) Colocasia IN GENERAL has a partially peltate leaf blade, while GENERALLY
Alocasia has any shaped leaf blade you want to imagine, from entirely
peltate to sagittate, to deeply pinnatifid!!!. GENERALLY Colocasia has a
small sterile region at the tip of the spadix, while GENERALLY Alocasia has
a longer sterile region at the apex of the spadix.

If you have a plant you are doubtful about, the best way to get an I.D. is
to post a picture of the plant, many will jump at the chance to I.D. it, or
at least give a good guess!

I again urge anyone who is seriously interested in Aroids to buy the book
'The Genera of Araceae' by S.J. Mayo, J. Bogner and P. Boyce, there you will
find MOST of the answers to any questions you may have about this wonderful
family of plants we SO love! It is available from the IAS on this list,
just post a request for information, it costs about U.S. $135.00.

Good growing,

Hi Christophe

Julius' descriptions of the differences between Alocasia and Colocasia is
great, but I can add another couple of differences concerning position of
inflorescences and fruits.

Colocasia produces inflorescences in a fan running away from the petiole
from which the infl. are being produced (i.e. the back of the spate faces
the petiole from which it was produced,mand, generally, produces several
infl. per leaf. Alocasia produces inflorescences running parallel to the
leaf and generally only one or two per leaf.

In fruit Alocasia produces rather large berries carried erect, and that
ripen orange-red (like Arisaema, Arum and most Amorphophallus), and each
contain one to three (rarely more) large, round seed. The fruits are
odourless. Colocasia fruits are carried on a nodding stalk, are small,
yellow-brown, fruitily scented, and contain many, small, ellipsoid seeds.
