( caespitosa = clumping; relating to a lot of scions, 或者 growing in tufts or clumps" )
例如子吹鳥羽玉 ( Lophophora williamsii var. caespitosa ), 但並不只限定在 L. williamsii 這個品種上才會有這種現象, 例如L. jourdaniana f. caeaspitosa , 姫春星 ( Mammilaria humboldtii var. caespitosa ) 等...
The form name "caespitosa" derives from the Latin word “caespes” which means “turf” and refers to the dense tufts of basal stems. ( The specific name implies: "growing in tufts or clumps")
不過文中提到一個特性重點, 就是 "... Some of the caespitose clones produce dozens (or hundreds) of very small shoots each of them never reach the dimension of a flowering plant, thus they are sterile and can be reproduced exclusively by cuttings."
