Wow, the Copiapoa looks great. You have some really nice pants, masscactus.

masscactus, Your plant looks great and the offsets too (though looks like it wants a repot soon.) I wonder what makes a plant offset as opposed to dichotomously split? Could it be crowding in a smalled pot encourages offsets? The habitat photos of M. microthele on Hugo's AfM site are all packed in t...

That is the best thing about this being an online guide. Synonyms can be easily looked up! Daiv, I would argue that looking up synonyms is the best thing here; the people and their attitude are what makes it the most amazing cactus ID site on the web. The other features (like looking up synonyms) a...

Hello Harry and iann, I have seen a colony of white Dudleyas growing on a bridge in a sycamore woods near Los Angeles coast (Greenleaf Canyon). I don't know what species, but I was quite surprised to see they were not growing in the sun, but rather pretty shady in the summer. Of course, the sycamore...

Thanks for an amazingly speedy reply, Hugo! M. microthele seems to be called M. formosa here, though I see on your site you have both formosa and mmicrothele listed. Also, you have great habitat shot! It looks like, for M microthele, that dichotomous splitting is the way it goes! If this was too eas...

Hi all! Here we go. Plant is about 4 years old and finally flowered. Looks like it is trying to split too! 7.5 cm diameter and flower is about 1 cm across. I assume it is a Mammillaria, but have been fooled in the past. : ) http://www.cactiguide.com/forum/userpix/1514_Mystery_mammillaria_01_1.jpg ht...

Wow - really looks like a nice fascinating plant!
Enjoy!

Thanks for the input. LOL, I was thinking some hybrid with a name like Anna Carina... I am much happier to have a straight species. Neal: The central growing point of yours(what's it called in cactus - terminal?)looks identical to mine with the depressed center and prostrate radial spines. But the f...

Hi all, You have been so awesome in your responses, I feel like buying more plants just to ask you what they are! : ) This plant is only 1 1/2 inches diameter. I got it at an Israel botanical garden sale. I suspect annabarina or whatever in the hard to read writing o the pot is a hybrid and the fuzz...

Thanks so much! This is amazing - habitat pics are really great. I never thought of Parodias and Tliiandsias together.

Again, thanks,

Shmuel

Thanks Mikayak, I saw that reference in the site search - but the overabundance of names was overwhelming. I thought maybe Rebutia atrovirens 'ritteri' by the flower, but I figured I would toss it out to the experts. Mybe pygmaea var atrovirens is different... I am an old timer - we used to match pl...

Hi all, You are terrific! I love the responses! The following was bought at the shop of a public cactus garden near Tel Aviv, Israel. Grease pencil writing on the pot has an illegible letter and then says atrovirens. The letter could be M, L R (Mammilaria? Lobivia? Rebutia?) With all the synnonyms f...

Actually, I was thinking Pediocactus knowltonii....but it was just a WAG (it does have purple flowers though) Looked like a good call, but the Turbinocarpus seems right now that I have direction. Thanks though for mentioning Pediocactus. I had never even heard of the genus before and now I was able...

Hi and welcome! that looks like Tubinicarpus valdezianus to me, great plant. peterb Wow! Thanks. I thought at first Mammillaria or else, with bated breath, Pelecyphora - and I see from the posted synonyms I was not so far off. By the way, the listing here http://cactiguide.com/cactus/?genus=Turbini...

Hi all! I just found this site - joined immediately and am overjoyed at the possibilities!!! I don't want to bombard you too much, so I will send my unidentified fotos individually (unless you want me to send more at once). By the way, I have been growing cactus for about 40 years, lots in L.A., but...
