Carpobrotus edulis (AIZOOACEAE.) Images for this profile are taken from the Maltese Islands at or after year 2000. |
|
Nomenclature and Basic Information |
Species name : |
Carpobrotus edulis(L.) N. E. Brown Published in Gen. S. Afr. Fl. Pl. 249 (1926) | Synonyms :
(basionym or principal syn.) |
|
Plant Family : | Aizooaceae
Rudolphi (The Fig-Marigold Family) 16 species from the Aizooaceae family are recorded from the Maltese Islands. | English name(s) : | Hottenot Fig, Kaffir Fig | Maltese name(s) : | Xuxet San Ġwann, Is-Swaba tal-Madonna | Status for Malta : | Casual or accidental alien species introduced in Malta rather recently and which is short-lived or resticted in small populations for a short time without becoming widespread. | Frequency : | Very Common Common Frequent
Scarce Rare
Very Rare Extinct
| Growth form : |
Raunkiaer lifeform [info]: CHAMEOPHYTE (dwarf or small shrubs)
Germination [info]: Dicotyledon | Legal Protection [link]: | Not Protected by Law (LN200/2011 or LN311/2006) | Red List (1989) : | Not listed in the Red Data Book of the Maltese Islands | Flowering Time : | Mar-Oct | Colour of Flowers: | Violet or Yellow | Remarks : | Many reports of this species refer to the closely related species C. acinaciformis where the main differences are in the sepals, ovary and receptacle of the flower, but usually, C. edulis has yellow flowers and C. acinaciformis has purple-magenta flowers. This species is closely related to Carpobrotus acinaciformis which apparently, in local literature there is confusion betwen the two. Conclusive identification relies on dissecting the flower and examine the number of locules and the longitudinal shape of receptacle, however long sepals of about 40-60mm, yellow flowers and straight leaves with equilateral triangular cross section are highly indicative of C. edulis . The variety C. edulis var. rubescens Druce (and perhaps artifial hybrids such as var. chrysophthalmus C.D.Preston & P.D.Sell) has purple flowers hence the colour of flowers is not enough to determine between the two species. Nevertheless, about 95% of the specimens examined, resulted to be C. acinaciformis in Malta, hence the use of C. edulis as the purple-flowering invasive species has to be ammended to C. acinaciformis . |
