Echinocereus
Echinocereus rigidissimus subsp. rubispinus L88
Echinocereus is a genus of flowering plants of the cactus family ( Cactaceae ). The botanical name of the genus is derived from the Latin word " echinus " for hedgehogs as well as the genus Cereus and refers to the columnar short, spiny plant body.
Description
The species of the genus Echinocereus grow individually or branching with prostrate to erect shoots, which are spherical to cylindrical. The roots are fibrous or bulbous. The plants reach heights of growth between 1 and 60 centimeters. Echinocereus pensilis can be up to 4 meters high under suitable conditions. On the tips of the 4 to 26, mostly clear and only rarely resolved in hump ribs, the areoles are able to spring from which differently shaped thorns.
The small to large, funnel- shaped flowers occur at the upper end of an areola or break through the epidermis. They are usually brightly colored and open on the day. Your Perikarpell and its corolla tube are occupied with spines, bristles and sometimes wool. The scar is usually green, but sometimes also colored white.
The ball - to egg-shaped fruits are green to red and usually spiny. They are most lush and open along a longitudinal slot. The sometimes fragrant fruits contain broad oval, black, gehöckerte seeds from 0.8 to 2 millimeters in length.
Dissemination
The distribution of the genus Echinocereus extends from the southwestern United States to southern and central Mexico.
System
The first description was in 1848 by George Engelmann. The type species of the genus Echinocereus is viridiflorus.
After Nigel Paul Taylor the genus Echinocereus is divided into eight sections:
- Section Morangaya: Long slender shoots with plant height of about 1 meter, rarely up to 4 meters. There are trained abundant aerial roots. There are eight to ten ribs available. The tubular, red flowers appear from areoles. Your scars are whitish.
- Section erecti: Short shoots of up to 1 meter in length, with eight to 23 ribs. The central spine is often flattened or angular. The wide treichterförmigen, differently colored, including yellow, flowers appear from areoles or rarely break through the epidermis. They are longer than 4.5 inches long. Their loosely arranged bracts are at the base of strong meaty. The outer of them are quite long, narrow and strong. The scars are deep green to almost white.
- Section triglochidiatus: The extended to short and stout and densely branched shoots are shorter than 60 inches. There are four to 16 ribs available. The pink, orange or red, hummingbird -pollinated flowers breaking through the epidermis. Sometimes they are schiefsaumig and sometimes they close at lunchtime, partially or completely. Your scars are bright green.
- Echinocereus section: As in the section erecti but four to twelve ( often up to 14 ) ribs, always breaking through the epidermis flowers from 2.5 to 101 centimeters in length and wider outer fleshy un less bloom cladding, which in an alcohol -formalin solution are colorless. The scars are light to dark green.
- Section Costati: As with the section Echinocereus but the flowers are brown in an alcohol -formalin solution.
- Section reichenbachii: Spherical to cylindrical shoots with three to 26 ribs and usually short, slender and very numerous thorns. The short-lived, differently colored, but never hummingbird pollinated and red or orange flowers appear at or near the areoles, very little through the epidermis breaking through. The significant flower tube is covered with numerous areoles above the Perikarpell. The very numerous, delicate bloom are not particularly fleshy at its base. The scars are light to dark green.
- Section Wilcoxia: → Main article: Wilcoxia
- Section pulchellus: As with the section Reichenbachi but the flowers drop significantly through the epidermis. Your Perikarpell and the corolla tube are occupied with few, often far apart standing areoles. The few and / or loosely arranged bracts are narrow. The little fleshy to dry fruits contain few seeds.
