VIRENS ssp. HASSEI (Rose) Moran, 1995

Synonyms :

Stylophyllum hassei  Rose (1903) / Cotyledon hassei  (Rose) Fedde (1904) / Echeveria hassei  (Rose) A.Berger (1930) / Dudleya hassei  (Rose) Moran (1957)

 

Distribution : USA (Califomia: Santa Catalina Island); rocky slopes close to the sea, 5 - 120m.

 

 

 

Differs from ssp. virens:

 

Rosettes 4 - 8 cm in diameter, with 15 - 30 leaves, richly branched, forming cushions to 1 m in diameter.

 

Leaves mostly erect or outcurved, semiterete and apically often terete, linear and hardly or not broadened above the broadened base, acute or acutish, often weakly attenuate, 5 - 10 (-15) x 0.6 - 1 (basally - 3) cm, farinose or rarely green.

 

Inflorescences scape 10 - 30 cm; inflorescence usually with 2 - 4 densely arranged not or 1x branched scorpioid branches, these 2 - 10 cm, with 3 - 15 (-29) flowers, pedicels usually 1 - 2 (-5) mm.

 

Cytology : n = 34

 

Differences to ssp. insularis, which also occurs on Santa Catalina Island, are the smaller size and especially the narrower semiterete leaves and the shorter inflorescences. The two subspecies apparently form natural hybrids (Moran 1995: 6).
