SOUTH AFRICA: Matjesfontein, _A. J. Austin_.
We are indebted to Mr. A. J. Austin for this charming little species of
_Romulea_, which is apparently undescribed. It was gathered at
Matjesfontein. The same species was collected a few years ago by
Schlechter (No. 8847) at Matjes River at an altitude of 2500 feet, and
distributed by him as _Romulea hirsuta_, Eckl., var. _aurantiaca_.
Although resembling _R. hirsuta_ in general appearance, it is easily
distinguished by the colour of the flowers and especially by the very
broadly membranous margins of the inner spathe valve. The flowers close
up at night.
Our knowledge of the genus _Romulea_ in South Africa is still very
meagre, and much field-work is necessary in order to understand the
range and variability of the species.
DESCRIPTION:--_Corms_ 1·5 cm. long, 1·2 cm. in diameter with brown
tunics. _Leaves_ 3-4 to a corm, 4-10 cm. long, 0·75 mm. broad, with five
deep and narrow grooves, acute, somewhat sheathing at the base and
forming a distinct neck, minutely ciliate. _Flowers_ 2-3 to a spathe.
_Pedicels_ 1·2 cm. long, subterete, glabrous, becoming spirally coiled
in old flowers. _Outer spathe valve_ 9 mm. long, 4 mm. broad,
elliptic-oblong, toothed at the apex, 9-nerved, with membranous margins;
inner spathe valve about same size as outer, deeply bifid at the apex,
5-6-nerved with very broad membranous margins. _Perianth-tube_ 5-6 mm.
long, campanulate; lobes 1·5 cm. long, 0·7 cm. broad, obovate, obtuse,
reflexed in the open flower, yellow in colour with a spade-like purple
mark on the three outer and smaller purple marks on the three inner.
_Filaments_ 9 mm. long, convex on the back, grooved on the front face,
broadened and pilose at the base, pilose on back about the middle;
anthers 4 mm. long, 2 mm. broad, elliptic, in flowers which have just
opened the anthers are somewhat joined and the stigmas appear between
the anthers. Ovary subglobose; style 1 cm. long, terete, glabrous; lobes
3·5 mm. long, each subdivided into 2 lobes 2 mm. long.
