- Cycas glauca hort. ex Miq., Comm. Phytog.: 127 (1840-1841).
- TYPE: Hort. Roterodam. (lecto (fide Stevenson & Hill) U).
Greek, glaucus, with a bluish waxy bloom, in
reference to the bluish glaucous leaves.
Described by Miquel in 1841 from cultivated material in European collections.
This sheet most
closely matches the basally restricted leaflets later described
by Miquel (1868).
Schuster regarded C. glauca as a variety of C. circinalis,
without really understanding the nature of C. glauca.
Broad bluish leaves, basally constricted leaflets.
Distribution and habitat:
Timor and Sumba only, in near-coastal forests.
Petiole 51 cm long, spinescent for 90% of length. Basal leaflets not gradually reducing to spines.
Median leaflets simple, strongly discolorous, 150-260 mm long, 13-18 mm wide, narrowed to 2-4.5 mm at base (to 15-35% of maximum width), 17 mm apart on rachis.
Fibrous layer absent; sclerotesta smooth. Spongy endocarp present.
