The Handbook of Succulent 上也沒有紀載。
感謝臉書上的花友Ya-ting Lin 提供照片,可以清楚的看到,葡萄甕是屬於雌雄同株異花的。
型態上來說:
公花有四片明顯的花辦,往後翻,四根雄蕊往中間靠,集中成一根,末端一坨花粉。
母花沒花瓣,有四個明顯的蜜腺,只有一根明顯的雌蕊。
一個花序裡面會有雄花和雌花,會同時開放,自交親合。
Cyphostemma 的自交親合性隨物種差異不同,有些要開好幾陀花序才有一個果實,有些一個花序就有10幾個。
Cyphostemma jutae are hermaphrodite,that is it has both male and female part on same plant.
But the detail structure of it;s flower is lacking.Is it synoecious (with perfect flower)?
or is it monoecious In a narrow sense ? (with male and female flower)
Thanks to my FB friend Ya-ting Lin i can have these great photo.
Flower Morphology of Cyphostemma jutae
Male flower:
With 4 obvious petal recurving, 4 stamen curve toward central and close together forming a single pole.Pollen can be seen as single blob on the tip.
Female flower:
With 4 obvious nectar glande. Drop of nectar is very obvious .Only 1 style.
A single inflorescence contain both male and female flower.Flower at same time.
self-compatible.
The degree of self-compatible vary in Cyphostemma for about 0.5 fruit per inflorescence to 10 more.
