alright, in a couple of previous threads titled "cactus heaven" an un-identified Trich was considered by a number of people to be a possible knuthianus. other people thought it a possible peruvianoid.
Ace & ferret posted some pics which looked almost identicle to the one that i posted. they all shared a number of characteristics which leaves no doubt in my mind that they are all the same species.
here is a pic of the plant:
so anyway the other day i received a cutting from an old cactus grower which was labeled T. knuthianus, which is this:
in my opinion the latter plant is clearly a different species from the former. the spines on the latter are MUCH more robust & there are many more spines present than there are on the former. the V notch on each plant, while in both it is very prominent giving the plant a very 'angular' appearance, is quite different in both plants. it is hard to tell from the photo's but seeing these two individuals in the flesh, while sharing a number of characteristics, they are just very different plants.
can the latter be positively ID'd as knuthianus?
if the latter is indeed Knuthianus & they are indeed 2 seperate species what in hell is the former?
