Flowers hermaphrodite, usually regular, small or rather 
large, sometimes axillary and solitary, often racemose, or 
solitary or umbellate at the apex of an elongated scape, 
the inflorescence centripetal; calyx free, or very rarely 
adnate to the ovary, four to nine-fid or parted, usually 
persistent; corolla hypogynous, generally gamopetalous, 
rotate, hypocrateriform, or infundibuliform-campanu- 
‘e late, with a short or elongated tube; limb four to nine- 
| parted or four to six-lobed, the lobes or segments 
entire, emarginate, or fimbriate-lacerate, imbricated or 
twisted in æstivation, rarely sub-bilabiate or wanting; 
stamens as many as the corolla lobes. Capsule one- 
-celled. Leaves exstipulate, sometimes all radical, some- 
times cauline, alternate, opposite, or whorled, simple or 
rarely lobed (in Hottonia, pectinate and multifid), The 
species are more remarkable for their beauty than for 
the little economic value they possess, Most of _ the 
flowers are sweet-scented. The order comprises twenty- 
one genera, and about 250 species. Well-known illus- 
trative genera are: Androsace, Cyclamen, Lysimachia, 
and Primula,

genus. The species is a remarkable, greenhouse rush, 
found in swamps and on the banks of rivers in South 
Africa. In its native habitat, it often increases to such 
an extent as to choke the rivers in which it grows. 
The leaf-sheaths contain a network of strong, black 
fibre, suitable for brush-making; and the leaves them- 
selyes are useful for plaiting and thatching. It should 
be grown in a compost of loam and leaf mould, and the 
pot stood in a pan of water. Propagated by division.
