Romulea sphaerocarpa
is an early-flowering species found scattered in sandy pockets on sandstone slopes. Originally known from near the Hex River Pass more recent collections have extended its range somewhat although it remains a relatively local endemic of the highlands south of the Tanqua Basin from the Katbakkies Pass in the north to the Waboomsberg in the south. Resembling
Romulea tortuosa
in its strongly flattened, fan-shaped corm,

sphaerocarpa
is distinguished by the solitary, sticky leaf usually covered by grains of sand and the less pronounced compression of the corm. Plants each produce a single flower.
