Another cactus given to me by a friend although he was not sure of the ID. He thought it might be Thelocactus bicolor? The new growth exhibited near the top is the growth since I have had the cactus. It is a Texas native. The bloom should be a big help in the ID. This might be a good one for peter to ID. Thanks in advance.

What are the identifying characteristics for it to be a type of bicolor in your opinion? Is it the uppermost spine coloration?peterb wrote:Hi Ed, definitely a form of bicolor. Interesting very pale flower and yellow stigma lobes. Not sure where it might fit in the many named and unnamed ecotypes from Texas. If you hadn't said it was from Texas I would have guessed bolaensis.

Hi Ed- well, the tuberculate ribs, general spine arrangement and appearance of the new growth all suggest Thelocactus bicolor, defined by a broad set of characters. The flower does appear to me to be unusual, perhaps a variant at the extreme pale end of bicolor flowers.
But really I'm mostly going on you saying it's a Texas native, as current understanding is there's only Thelocactus bicolor and bicolor ssp. flavidispinus in Texas. The plant doesn't look like flavidispinus to me, as it seems too columnar and with different spines than I'm used to seeing on flavidispinus.

No I can't make it this year but a few members from our Austin Cactus Club are attending. It should be a good time. Maybe next year for me.peterb wrote:Hi Ed- yes, I'll be there Saturday and Sunday. Looking forward to the CactiGuide get together on Sunday.
You making the trip?
