Astrophytum
(Lemaire 1839)
Etymology: Greek [Aster], Star and [Python], plant. Star-shaped plant.One of the most popular for its relatively easy culture, its spectacular flowering and its various forms genres. It has resulted in hundreds of cultivars prized especially for the Japanese, who have made an art cultivation.
It is possibly the most popular genre among growers despite containing only 5 species.
Reproduction is almost exclusively by seed and the growth rate is intermediate. All species of this genus are self incompatible, which means that two copies are needed to produce seeds. These seeds are of the split type with a high germination but poor durability.
The species of this genus can be divided into two groups according to their genetic affinity and weather resistance being relatively easy hybridization between members of the same group and more difficult between members of different groups.
Group 1:
The species of this group are relatively sensitive to cultivate have in common, unlike what happens with group 2, the presence of a reddish area in the center of the flowers are yellow otherwise. This group includes: A. Asterias (Lemaire 1868), A. Coahuilense (K. Kayser 1932) and A. Capricorne (Britton & Rose 1922).
Group 2:
Cultivation easier perfectly resist something fresher and humid climates. This group includes: A. myriostigma (Lemaire 1839) and A. ornatum (Britton & Rose 1922).
