wholly overtopping the gland. Ovary pubescent ; perianth with 1, 2 or 
all 3 of its minute deltoid lobes terminating in a filiform or linear- 
subulate tail 4-2 lin. long and as long as the young ovary, pubescent ; 
styles connate at the basal half, more or less deeply bifid above.

Nearly allied to S. angolense, but differing in the very much shorter cuneate 
part of the leaves, which are not at all oblanceolate and rather differently veined, and 
the branches of the cyme are stouter.

Apparent flower consisting of a number of stamens (really male 
flowers, each consisting of a single stamen jointed to a pedicel and soon 
falling away from it, without or rarely with a minute perianth just ut 
the articulation) mingled with membranous scales or bracteoles, Me 
or without a stalked ovary (really a pedicellate female flower, wit Aa 
without a minute 3-lobed or very rarely cup-like or tubular periant ‘I 
the base of the ovary, but without a membranous tubular involuce 
surrounding the pedicel) in their midst, contained in a calyx-like or. 
shaped involucre, the whole resembling a small hermaphrodite er i 
flower. Involucre consisting of a cup with an outer series 0 pee 
(usually 5) glands, distinct and equally spaced or rarely united, - ri 
2-horned, petal-like or divided, alternating with an inner series aie 
(usually 5) membranous erect or inflexed fringe-toothed lobes. oa a

tudinally dehiscent. Ovary partly or wholly included or exserted, é 
(rarely 2-) celled, with a single ovule in each cell, pendulous from pile ae 
of the inner angle; styles 3, rarely 2, free or more or less united sear : 
entire or bifid at the apex. Fruit a 3- (rarely 2-) celled capsule ; a

The cup-like involucre of this genus, which so closely resembles the oC ine 
hermaphrodite flower, is really composed of two alternating whorls of 4— d the

inner whorl in the fringed or ciliate lobes. Occasionally abnormal flowers 7 aa 
met with in which this is clearly shown, by one or more of the outer whor. In the
