Re: [Aroid-l] Hybrids?

**&* B* <b*@malesiana.com>**

Curiously, while natural aroid hybrids seem to be not at all common in

nature, Arum seems to be profligate, with the following confirmed (order of

parents is pollen:seed):

A. apulum x A. italicum ssp. italicum (Italy)
A. creticum x A. idaeum (Crete)

A. cylindraceum (syn. A. alpinum) x A. maculatum = Arum x sooi (first

recorded for Hungary but present almost everywhere that the two species meet

in Europe)

A. concinnatum x A. cyrenaicum (Crete)
A. idaeum x A. creticum (Crete)

A. italicum ssp. italicum (also reported as ssp. neglectum) x A. maculatum

(France)

A. palaestinum x A. dioscorides (Israel)
A. purpureospathum x A. concinnatum (Crete)

What is most interesting is the number of hybrids occurring in Crete.

Arisarum also produces a hybrid between A. vulgare x A. simorrhinum, the

swarms of offsprinr of which have variously been used to describe a whole

raft of ssp. and vars and haev been used to taxonomically merge the two

parents under the name A. vulgare. In fact, the parents are very distinct.

Here in Sarawak I know of at least two populations of Alocasia robusta x A.

princeps; and one of A. reversa x A. ridleyi.

I don`t believe that anyone denys that there are 'natural hybrids' in

nature. BUT---'mother nature' usually makes these 'natural hybrids' a

rare occurence, and in many cases a Biological dead-end. Think about a

mule (donkey X horse). In other hybrids, there is no or limited

fertility in the hybrid. The statement 'pollen goes wherever it may' is

true in very few cases except wind-pollenated species, it MUST be

transported from plant to plant (or animal to animal), and there are

mecanisims to ensure in most cases that the pollen from one species goes

to that species (distinct different odurs or shape/colors of blooms in

plants, different behaviors, etc. in animals/birds).

But yes, there are 'natural hybrids' that do sometimes occur, even in

aroids!

Can anypne deny that in nature there may be some "natural hybrids"?

Pollen goes wherever it may--
