Literature review<br />
flattened upper sides which are curved to the fruit. The fruiting peduncles <strong>of</strong> R.<br />
sabulosa, on the other hand, are commonly more slender and rounded in section and<br />
remain suberect in fruit. The peduncles <strong>of</strong> the latter species also remain suberect<br />
during fruiting. Apart from these morphological differences R. sabulosa is also<br />
restricted to light sandy clay soils near Nieuwoudtville whereas R. monadelpha is<br />
found on heavy, dolerite clay in several localities along the Bokkeveld and Roggeveld<br />
escarpments (MANNING & GOLDBLATT, 2001). MANNING & GOLDBLATT (2001)<br />
places this species in the subgenus Spatalanthus.<br />
2.2.11 Romulea pearsonii<br />
The flowers are lemon-yellow with elliptic tepals and the fruiting peduncles are<br />
suberect (DE VOS, 1983; MANNING & GOLDBLATT, 2001). Both the outer and the<br />
inner bracts are green. The outer bracts are firm and closely veined with narrow<br />
brown streaked membranous margins and an apex (DE VOS, 1983; MANNING &<br />
GOLDBLATT, 2001). The inner bracts have broad brown streaked membranous<br />
margins (MANNING & GOLDBLATT, 2001). The plant flowers in August to<br />
September with 1 to 3 flowers (DE VOS, 1972; MANNING & GOLDBLATT, 2001).<br />
Plants <strong>of</strong> this species have a height <strong>of</strong> 100 to 250 mm (DE VOS, 1983; MANNING &<br />
GOLDBLATT, 2001). The stem is completely subterranean or reaches 30 mm above<br />
ground (DE VOS, 1983; MANNING & GOLDBLATT, 2001). The plant has 3 to 4<br />
filiform leaves <strong>of</strong> which 2 are basal (MANNING & GOLDBLATT, 2001).<br />
R. pearsonii is restricted to higher elevations in central Namaqualand (MANNING &<br />
GOLDBLATT, 2001). Here it occurs from Grootvlei and the main Kamiesberg range<br />
and grows in sandy and granitic slopes and flats (MANNING & GOLDBLATT, 2001).<br />
MANNING & GOLDBLATT (2001) places this species in the subgenus Romulea.<br />
2.2.12 Romulea rosea<br />
The flowers are pink to magenta or white with a purplish zone around the yellow cup<br />
and are occasionally scented. The tepals are elliptic to oblanceolate and 4 to 6 mm<br />
long. The outer bracts have narrow membranous margins whereas the inner bracts<br />
have wide brownish membranous margins (MANNING & GOLDBLATT, 2001). R.<br />
rosea flowers from July to October and the plants have several flowers (DE VOS,<br />
1972; MANNING & GOLDBLATT, 2001). These plants reach 150 to 600 mm from the<br />
