Turbinicarpus flaviflorus

[Jens]

Those grass-like spines on T. flaviflorus are really something!
Yellow flowers are not too comon in Mammillaria, aren´t they? here is one

Hi,

I thought I'd add a picture of my Turbinicarpus.

Beautiful picture Sheila !

I found another yellow flower on a Mammillaria in the archive
M. sphaerica

[Lithos]

Here is another yellow flowered Mammillaria

Mammillaria solisiodes

Some other yellow flowers - apoligies for dusty pictures - slides scanned today from pictures taken in 1987, not always stored appropriately !

Strombocactus disciformis

Ortegocactus macdougalii

[Jens]

Wonderful specimen of both species, lithos!
The flowers of Ortegocactus are such a shiney rich yellow,- making them difficult to photograph because of the strong reflections.
May happen with some Thelocactus too

Strange flower this one I tell you. Love that points on it.

While most fall out of the season, at least one species qualifies as a "summer flower":

Thank you Jens - the pictures were taken with an old Olympus OM10, with the standard 50mm lens reversed and taped onto a cardboard tube which was taped to the camera body - real high tech! but it was 26 years ago
