[Avodah] Male and Female Gemstones !?

[SBA]

An interesting Rabenu Bachaye that I came upon last week - on Kapos
"Temarim".

(Rashi writes that Kapos is "chaser vov - lomad sheino ela achas" ie, we
only require a single Lulav.)

Rabenu Bachaye refers to the word "Temarim" - loshon rabim, and explains
"...umilas 'temarim' - lefi shehem shenayim - zochor unekeiva. 
V'im lo yinteu ken, lo yichyu. 
Ki bechol haminim kulom - gam betzemochim gam bedomem - motzinu bederech
hateva zochor unekeva". (V2, p 72)

The Shaarei Aharon explains 'bedomem' - 'kavonoso be'avonim yekoros' =
gemstones.

This is new to me. Anyone know more about this?
