Echinocereus ID please.

Difficult to ascertain the size of the plant - Acifer can grow quite large whereas my Salmdyckianus are on the small side. My first feeling was that the plant is a Coccineus var.

[DaveW]

From the length of spines, and comparing the pictures in the book "Echinocereus" by Wolfgang Blum, Michael Lange, Werner Rischer & Jurgen Rutow the nearest match from the long spines is E. acifer. It does not match with E. coccineus. They give the flower as:-

Flower bud blunt woolly.

Flower shape tubular, length 80-100mm, diameter 10-30mm. Flower colour light red/red pink, throat yellow.

Tube length 45-65mm, diameter 7-20mm.

Tube colour reddish. Ovary length 15-20mm, diameter 10-15mm, colour green.

Petals: length 25-35mm, width 3-15mm.

Filaments whitish, pink tips.

Anther colour purple, pollen colour yellow-orange.

Style 70mm long, 1.5-2mm wide, colour whitish-greenish.

Stigma lobes 10, length 8-12mm, colour green.

All this group of Echinocereus are a bit variable in spine length so it is often difficult to relate them to illustrations.

Those colours are unbelievable! W~here can i get cactus of these species?

[DaveW]

Most nurserymen should have some Mike. Not sure what I have as cuttings, I will have to have a look. I can probably find you a cutting of E. procumbens, which probably has the largest flower of the Echinocerei at about 5" across fully open. See:-

Aside from the flower colour this looks not unlike a plant I have labelled Echinocereus roemeri.
