description
Vegetative characteristics
The Canary Islands stendel is a perennial herbaceous plant and reaches heights of 10 to 40, rarely up to 60 centimeters. As over-control organs, it forms two round, undivided plant tubers .
The stem has two sheath leaves , above it two basal leaves lying on the ground . With a length of 4 to 18 centimeters and a width of 1.2 to 7 centimeters, they are oblong-lanceolate to ovoid, shiny green and spiky.
Generative characteristics
The flowering period extends from October to April. In the terminal, unbranched and 4 to 17 centimeter long inflorescence there are 2 to 30 flowers, loosely distributed on all sides. The bracts are 9 to 11 millimeters long and 2.5 to 4 millimeters wide, they are half or three quarters as long as the ovary and adjoining it.
The fragrant, hermaphrodite flowers are zygomorphic and threefold. The bracts are yellowish green. The lateral sepals are obliquely ovate, directed somewhat downwards and turned back. The middle sepal and the petals form a helmet. With a length of 7 to 10 millimeters and a width of 7 to 9 millimeters deep, the lip is three-part with linear spreading side lobes and an almost identical, slightly shorter, undivided middle lobe. The spur is narrowly conical, curved downwards in a semicircle and as long or slightly longer than the ovary.
The number of chromosomes is 2n = 42.
