Help me identify what sex these Chamaedorea are please

[Josh76]

Hi. I have three Chamaedorea flowering in my garden at the moment. Can anyone help me to identify what sex they are?

#1

C. microspadix

#2 C. radicalis

#3 C. pochutlensis

Confident the C radicalis is female. Slightly confident the C microspadix is too. The C potchutlensis I’m not sure but it does look a bit like my C costaricana female inflorescences so maybe they’re all female.

The pochutlensis is a female

Thanks! So I really need to find some pollen!

Josh, I can't speak for the other two species since I don't grow them.  I have a hard time distinguishing between the two sexes in Chamaedorea but with radicalis I found that the inflorescence of the male is jam packed with flowers while the female inflorescence has more space between the flowers like on yours.  I assume that this allows the fruits to have room to expand.  And there seems to be multiple female plants for every male.

As a rule of thumb, this seems to be true for most Chamaedorea sp I’ve grown in terms of the more spaced out female flowers. On balance I’d say I have more male than female plants overall though. I’d be curious to know if a large study has been done to know the % of each sex.

First you should ask which pronoun they prefer and which gender they identify as. Get with the times kiddo

Peachy (Cisgender female)

I think the microspadix is male. They should open up and drop pollen everywhere.

The radicalus looks female, but you may need to wait a bit to see.

The third one is female.

This is exactly what @Darold Petty told me about my C. costaricana

That's a nice compliment!  Darold is a great palm grower!
