Rhapis

Recommended Posts

@DCA_Palm_Fan It is hard to say which species of Rhapis the smaller one may belong to. For comparison I have attached two further photos of the smaller suckers of my female (β) Rh cochinchinensis/laosensis. — The reduced number of leaflets is normal after the dark season: the more light the more leaflets.

@DCA_Palm_Fan Another example for reduction of leaflets from 6 to only 1:

Very interesting.   So is this something that is unique to each species?  Or something that is seen across the entire genus?  

 

Any thoughts about the growth rate differences I mentioned and could that be an indicator of a different species?

A to the last Q: I don’t think so. E.g. the growth rate of suckers from suckers is bigger than the growth of the primary stem from seeds. Generally Rh excelsa and Rh humilis seem to grow quite fast because they are grown in most (or latter in all) cases from suckers.

A to 1st & 2nd Q: This is common to all Rhapis spp.

Here are the 5 Rhapis vidalii (Averyanov's Lady Palm) seeds I got via RPS: https://www.rarepalmseeds.com/rhapis-vidalii  Two seemed to have been damaged in transit. Three look like they could still be viable. I'm keeping them on sphagnum over heat after soaking in water for a day. Now the waiting begins... :unsure:

Throw the two seeds covered with mould :sick: away and keep the other three seeds clean; the greatest problem of Rhapis seeds is MOULD :evil: ! Good luck! :greenthumb:

Pal: I'm not sure that is mold.  It looks more like the crushed seeds' endosperm, which of course would be a prime medium for fungal culture! :bummed: I will defer to your experience germinating Rhapis palm seeds and discard those two. :crying: Thanks for your advice! I just sprayed the remaining seeds with some copper fungicide as an added precaution.

If it is part of endosperm which got liquid it is still worse … :sick:

Too bad palms in this genus are dioecious.  That means I need at least two seeds to germinate: one male and one female! :unsure:

Or you get a plant with male & hermaphrodite flowers:

If only I have such good fortune with my plants! :)
