Astrophytum asterias "5 RIBS"
RIBS指的是棱的数量Astrophytum asterias "5 RIBS"就是指5棱兜，兜的命名上很大程度上根据特征来命名，兜的棱数一般都是8棱，前面一篇文章翻译就有所提及，5棱算是比较少有的稳定的棱数
A. asterias 5 ribs type growing together with a 10 ribs one.
Generally this species has eight ribs, few or more ribs are quite rare.

Description: Normally Astrophytum asterias seedling have the standard 8 ribs, while only a small number of them have few or more ribs. The form with only five ribs, is particularly rare because many of the 5 ribbed seedlings that occasionally appear will usually develop additional ribs in a few years as they age. So it is quite exceptional to see an old A. asterias with five stable ribs. This form however looks suspiciously hybridized with myriostigma or coahuilense and probably is not a pure 100% asterias. Cultivation is not too difficult in a greenhouse, although they grow quite slowly. The plants need a loose well-drained mineral soil. They need a good amount of light. Watering can be done weekly during the summertime, if the weather is sunny enough, with a little fertilizer added. Kept this way, plants will show a healthy, although slow growth. They arefrost hardy to -4° (-10°) C 描述：通常星叶球苗有标准的8根肋骨，而只有少数人有几个或更多的肋骨。这种形式只有五根肋骨，特别罕见，因为偶尔会出现的5个肋骨苗的许多，随着年龄的增长，通常会在几年内形成额外的肋骨。所以这是很特殊的去看一个老的海星五稳定的肋骨。这种形式，但是看起来与myriostigma或coahuilense可能不是一个纯100%海星。
在温室里栽培并不太困难，尽管它们生长得很慢。这些植物需要疏松的排水良好的矿质土壤。他们需要大量的光线。如果天气足够晴朗，加上少量肥料，夏天可以每周浇水。保持这种方式，植物会表现出健康，虽然生长缓慢。它们是耐寒到- 4°（- 10°）C。 根据翻译所得资料在幼苗期出现5棱并不能判断就是5棱兜，所以买5棱兜的时候还是尽量要买亚成，幼苗期的5棱随时间长大可能会增加棱数
