Xerophyte

Seeds

Black 1,5 mm.

Description

Shrubby, scarcely branched, initially erect, later sprawling or clambering.

Roots

Tuberlike, contrarily to Echinocereus kroenleinii, the underground storage organ similar to dahlia tubers is not capable of producing new shoots. Those sprout out only from the main cut stem. Each plant can have up to 8 tubers, 10-20 mm in diameter, with a length of 60-100 mm. The colour is light brown in youth, later dark brown.

Note

It apparently looks like some Peniocereus species. However the flowers, fruits, and seeds of Echinocereus poselgeri are characteristic for Echinocereus, somewhat comparable to those of Echinocereus reichenbachi.

Flowers

Pink Rose/Mauve Magenta (Pink-Purple).

Blooming Season

Late Spring/Early Summer.

Spines

Tan-greyish white; 1 central up to 9 mm long, enlarged at its base, 4mm long; 8-15 straight radials, 4,5mm long, closely appressed (except at the stem tip)

Ribs

6-10.

Stem

Very tall and slender, dark coloured up to 1.2 m long and 2 cm in diameter.

Fruits

Ovoidal 20 mm Long, 10-15 mm Ø, dark green to brownish, pulp white
