球根花卉是指地下茎或根发生变态,呈球形或状的多年生草本花卉。按其地下茎或根部的形态结构,大体上可分为5大类:

(1)#鳞茎类。 地下茎呈鳞片状。外被纸质外皮的叫做有皮鳞如郁金香、水仙、朱顶红等;在鳞片的外面没有外皮包被的叫做无皮鳞茎,如百合等。

(2)#球茎类。 地下茎呈球形或扁球形,外被革制外皮,如唐菖蒲、香雪兰等。

(3)#根茎类。 地下茎肥大呈根状,上面有明显的节,新芽着生在分枝的顶端,如美人蕉、姜花、荷花、睡莲、玉簪等。

(4)#块茎类。 地下茎呈不规则的块状或条状,如马蹄莲,仙客来、大岩桐、晚香玉等。

(5)#块根类。 地下主根肥大呈块状,根系从块根的末端生出,如大丽花等。
