id Guihaia

[gyuseppe]

that Guihaia, they are different

the first 2 are the same, but the 3rd is different, they are many years old, very slow growing

[Phoenikakias]

As far as I can observe in third picture, also this specimen bears fibrous spines. Where did you get it from. It may well be natural variation or different stage of growth (stage of growth  must not be always related to age, specimens in optimal conditions may mature rapidly while same specimens in adverse conditions may remain for ever juvenile). Just out of curiosity have your specimens ever bloomed and what gender are they? Besides do you believe that a Guihaia can hybridize with Trachycarpus or even Rhapis?

konstantinos are 2 meters away, so they get the same amount of solar hours, but why are they different? ,  
they are all suckers  ,  I think they are 2 different species, I made them from seed in 2008, if I remember correctly I got the seeds from europalms (belgium)
no they have never flowered
no, I'm sure they can't hybridize with Trachycarpus and Rhapis

It does appear different . Does it have the white underside on the leaflets? I have had one for over thirty years and it hasn’t increased in size but gets 1-2 fronds a year. Super slow grower here . I have it is sun with gravel around it . Mine has never flowered either.  Harry

Gyuseppe, Guihaia have reduplicate leaflets which is unique and help to ID when compared to other genera. It is hard to tell from the photos, but I think I can see this trait in the first two photos (that is, leaflets are A shaped rather than V shaped). Does the other palm also have this trait? I’ve added a photo which shows typical G argyrata leaflets to help explain. 
 

You’re right. The last photo looks different to me.  The leaflets look thin and not stiff from the photo unlike G argyrata I’ve seen.  G grossifibrosa does have more of this look but still has reduplicate leaflets.

Tim, this photo of yours looks a lot like my first 2, photos 1 and 2.

Can you shows more pictures of this third specimen from different perspectives and other leaves of same plant? I have a male and a female specimen in my garden growing next to each other. The male one looked a bit different for many years but now it looks more similar to female  I will post pictures.

konstantinos I actually don't know how to put photos on the PC, my son does it, but he's very busy with work, he has 2 jobs and gives physics and mathematics lectures to university students, he has 3 degrees, he's a mathematician and a physicist

[happypalms]

Nice one. I was going to suggest @tim_brissy_13 is the man for this situation but he’s already onto that!

[palmtreesforpleasure]

I think the 3rd picture looks like my

Guihaia grossifibrosa

[gyuseppe]

Thanks colin
I didn't know that this species is also cultivated in Australia

[palmtreesforpleasure]

My Guihaia grossifibrosa is about 20 years old and only 40cm high.

I have never seen anyone else who has one in Australia, hopefully someone else has one

Regards

Colin

konstantinos very interesting these photos

[gyuseppe]

This weed grows everywhere especially on walls

[SubTropicRay]

All nice specimens.  This palm has become rare in cultivation.

Hello my friend Ray!

yes, seeds are not very easy to find, konstantinos had sent me some seeds in 2019, but I never sowed them, I had just discovered that I had a bad disease, luckily I am still in this forum with all my old friends, and I also made new friends with new people from this forum
