Haworthia jadea (Hayashi): Mini article by Gerhard Marx.

Haworthia jadea was discovered by Gerhard Marx in 1990 during an effort to locate Haworthia picta var janvlokii. It occurs on the same ridge as Haworthia picta var janvlokii but about 2 km to the east.

Initially it was considered as just a small form of Haworthia bayeri, but gradually it became clear that it differs from typical Haworthia bayeri in numerous characters.

The main and most significant difference is that it flowers three months later than typical Haworthia bayeri and the flowers are smaller, softer and with narrower perianth tubes. Haworthia jadea is also consistently smaller with fewer leaves per rosette than Haworthia bayeri and most striking is its distinct sea-green in colour which inspired the name. The central new leaves of Haworthia jadea are also produced at a slight twisted angle which is not found in Haworthia bayeri. Haworthia jadea is closest related to Haworthia hayashii and the closeness of the relationship between them needs further investigation. Haworthia hayashii flowers the same time as Haworthia jadea but is a larger plant with more leaves per rosette. Both the latter seem to be transitional elements between Haworthia bayeri and Haworthia indigoa and Haworthia truteriorum to the south.

Haworthia jadea is so far known only from a very small area on the eastern part of the Paardeberg, south of Dysselsdorp.
