Haworthia arachnoidea Haw.

 

위키 설명

 

Haworthia arachnoidea, locally known as "papierrosie" (paper-rose) or "spinnekopnes" (spider-nest), is the type species of the genus Haworthia, in the family Asphodelaceae, in the Western Cape Province of South Africa.[1]

 

 

 

Description

 

The plant has numerous dark green leaves, covered in translucent bristles, in a dense rosette. The leaves themselves are without translucent tips, unlike some other Haworthia species. The rosettes dry and contract in the arid summers.

 

It is sometimes confused with the widespread Haworthia decipiens (decipiens = deceptive) which occurs in the Great Karoo to the east. However H. decipiens has shorter, flatter, wider leaves; a lighter colour; translucent leaf tips; larger and sparser bristles which are mainly only on the leaf margins; and only a very weak leaf keel.[2]

 

Distribution

This most well-known form of this species occurs in the Breede River valley, in the areas of Worcester and Robertson (H. arachnoidea var. arachnoidea). Other varieties of this same species occur northwards into the Namaqualand (var. namaquensis), and eastwards as far as Port Elizabeth (vars. xiphiophylla, aranea and setata).

 

It occurs in a wide range of habitats and usually in the shelter of protective rocks and shading plants. It is a widespread and extremely variable species, with no typical form. There are also a range of intermediate forms between this species and some of its neighbouring species.

 

Intermediate forms exist in the transition between this species and Haworthia decipiens to the east. Also with Haworthia mucronata to the south-east. Many of these intermediates are treated as a variety, and given the name Haworthia

arachnoidea var. nigricans. To the north, it joins its relative, Haworthia nortieri.[3]

Haworthia decipiens Poelln.

Family: Asphodelaceae

Haworthia decipiens ("Papierrosie") is a species of Haworthia, in the family Asphodelaceae, in the Western Cape and Eastern Cape Provinces of South Africa.[1]

 

Description

 

Haworthia decipiens is frequently confused with its western relative, Haworthia arachnoidea and is both variable and hard to identify ("decipiens" = "deceptive"). Like its relatives, it has rosettes of dense succulent leaves, which dry and contract during drought, and are covered in soft bristles

 

This species can be distinguished by its shorter, flatter, wider leaves; a lighter colour; translucent leaf tips; larger and sparser bristles which are mainly only on the leaf margins; and only a very weak leaf keel.

 

It has a range of local forms and varieties. To the west, this species gradually becomes Haworthia lockwoodii, and to the south-west it becomes Haworthia mucronata (south of the Swartberg Mountains).

 

Flowering time is in the Spring.[2]

 

Distribution

This is a widespread species, occurring from near Prince Albert in the west, along the north of the Swartberg Mountains as far as Uniondale and Willowmore in the Eastern Cape. It occurs in a wide range of habitats and usually in the shelter of protective shading bushes.
