Cotyledon woodii is a species of the genus Cotyledon in the thick-leaf family(Crassulaceae).

description

Cotyledon woodii grows as an upright, branched shrub with a height of up to 120 centimeters. The shoots that become woody with age have a flaking bark, young shoots are succulent and green. The green or obovate and obovate, flat leaves are 2 to 5.5 inches long and 1 to 2.5 inches wide. The base of the leaves is wedge-shaped, the upper edge of the leaves is reddish to about halfway. The bare leaves have pointed tips and are sometimes covered with glandular hairs .

The inflorescence usually consists of single flowers, in exceptional cases up to 7 centimeters long dichasias are formed. The flower stalk becomes 8 to 10 millimeters long. The triangular sepals are 5 millimeters long and wide. The orange to red colored flower tube is slightly narrowed towards the mouth and reaches a diameter of 12 to 22 millimeters, at the base 11 to 15 millimeters. The bent back corolla lobes are up to 12 millimeters long. The 3 stamens protrude up to 6 millimeters. The elongated anthers are colored yellow and are 2.5 millimeters long. The nectar flakes, which are elongated across the length and have sanded edges, are yellowish and 1 × 3 millimeters in size.

Distribution and systematics

Cotyledon woodii is widespread in the South African provinces of the Western Cape and Eastern Cape in the Succulent Karoo in subtropical thickets.

The first description as Cotyledon woodii by Selmar Schönland and Edmund Gilbert Baker was published in 1902.

Synonyms are Cotyledon ramosissima var. Woodii (Schönland & Baker f.) Schönland (1915) and Cotyledon salmiana var. Woodii (Schönland & Baker f.) Von Poelln. (1936).

Several cultivars are known:

  • 'Gamtoos', forms upright to rounded subshrubs with sticky leaves; comes from Kouga Dam in the Eastern Cape Province
  • 'Green Eggs', forms upright small shrubs up to 30 centimeters in height. The glossy green leaves have a red border at the tip; comes from Port Elizabeth in the Eastern Cape Province
  • 'Gray Eggs', forms upright, rounded half-shrubs with gray and smooth leaves; comes from Kouga Dam in the Eastern Cape Province
  • 'Konga', forms shrubs up to 10 centimeters in size. Obovate leaves that reach a size of 4 × 2.5 centimeters are formed on the glaucous and green shoots. They are glaucous and blunt and have an attached tip. The inflorescence is up to 8 centimeters long and consists of 1 to 2 dichasias. The sepals are 8 millimeters and the tubular corolla 25 millimeters long. The green tube has a diameter of 10 millimeters at the base, which narrows to 8 millimeters towards the throat. The reddish corolla lobes are 20 millimeters long. It is assumed that this cultivar is a hybrid between Cotyledon woodii and Cotyledon velutina .
