Origin and Habitat: Southern Africa (Richtersveld), southern Namibia.
Habitat: The plants is from the winter rainfall of Southern Africa's Namib Desert and occur in very arid, rocky places on hills and mountains. They rely on winter rains that average around 110 mm or less per annum. It is not at all uncommon in this area for summer temperatures to rise to 46º C and years may pass before any rain falls.
Ecology: The bright yellow flowers produce nectar which is harvested by sugarbirds and ants. Generally, flowers are pollinated by bees and ants. When capsules dry out, the winged seeds are carried by the wind, often landing in bushes where they germinate, making full use of the shelter and shade. Plants eventually outgrow the nurse plant, killing it in the process. The fleshy leaves and stems act as water reservoirs in times of drought and the grey powder on the stems reflect intense heat away from the plant.Common Names include:
ENGLISH: Maiden's Quiver Tree
AFRIKAANS (Afrikaans): NooienskokerboomDescription: It is a slow growing tree (shrub) type aloe known for its many branches and smooth, white stems, and without a doubt the most profusely branched of all aloes. It will form a succulent bush up to 1,2(-1,8) m tall and wide. Other than this low branching habit and usually smaller leaf size, it is virtually identical to Aloe dichotoma, and some consider it a subspecies of A. dichotoma. Eventually forms large mounds.
Stems: As mentioned before, this aloe forms many branches from the ground level. This is the only significant difference between A. dichotoma and A. ramosissima. Branching continues as the plant becomes older, resulting in a dense, almost spherical shrub. The trunk is normally very short smooth and covered with strips of satiny, waxy, powdery silver-pink-brown coloured bark, which acts as a sunscreen in the harsh climate. The plants tends to be longer-stemmed and less branched in more arid areas.
Leaves: The branches end in small rosettes of fleshy, oblong leaves, each up to 200 mm long and 20 mm wide at the base. The leaf colour is glaucous-green or yellowish green, often with a pinkish tinge. The margins have narrow edges with small brownish teeth; base encircling the stem.
Flowers: Bright yellow, comparatively large, tubular, conspicuous, swollen, fleshy on a usually 3-branched short inflorescence, up to 200 mm long.
Blooming season: Winter: Definitely slow to flower, like Aloe dichotoma, takes quite awhile before it blooms, the first flower will be produced when plants gets 1-1,5 m of height (about 10 to 15 old).
Fruits: Shiny and smooth dry capsule that split into three, remaining fused at the base.
Seeds: Narrow, winged, up to about 30 x 18 mm.'식물 > 들꽃-백합과(Liliaceae)' 카테고리의 다른 글
