南美花仙人掌是原产南美的以赏花为主的球形掌类花卉的统称。总数共数百种,除少数种类外它们的刺和毛的观赏性稍逊于北美原产的球形种类,但花的观赏性却很强。更难得的是大多数种类对我国气候较适应,栽培简便,一般初学者都可以在几年之内就能欣赏到花的艳姿。目前许多爱好者都想进一步搜集栽培,但缺乏引种必须的资料,因此尽管在近年出版的几本书中已介绍了几十个常见种,还是不能使这些爱好者满意。为此在这里再介绍一些有代表性的种类,希望引起大家的兴趣。1.绯花玉(Gymnocalycium venturianum)原产乌拉圭。扁球状,直径5-6.5厘米,表皮深绿色。具9棱,棱为颚状突起分割。周刺7,长1.5-2厘米,柔软,向外侧弯曲,刺上部近白色,基部鼠灰色,通常无中刺。花漏斗状,短花筒,花冠直径6.5-7厘米,鲜红色,花丝淡红色,花药黄色,花柱艳
