very short filaments crowned with a peltate gland; those of the inner 
row 10, fertile, free, alternating with the barren exterior stamens, much 
exserted, with subulate filaments, and ovate, erect, short, didymous, 
splitting anthers. Ovary free, deeply 5-furrowed, formed of 5 indupli- 
cate-valvate carpels, 1-celled, tapering at apex into a subulate, exserted 
style; ovules sutural, indefinite. Capsule 5-lobed ; its carpels folli- 
cular, papery, slightly cohering at the sutures ; seeds minute, with mem- 
branous testa, copious, fleshy albumen, and a straight embryo. Harv. in

A middle-sized tree, with alternate, simple, and exstipulate leaves. Petioles

A small tree or large shrub, with light porous wood and gray bark. Branches and 
twigs leafy near the point, bare below ; flowering branches naked for a space below 
the raceme. Leaves on long petioles, subrotund, deeply cordate at base, 2-4 inches 
in diameter, multilobulate and crenate, glabrous, but minutely glandular on the sur- 
face. Racemes very dense, 2-4 inches long, many-flowered. Pedicels glabrous, 
2 inch long, with a lanceolate bract at base. Calyx continuous with the pedicel. 
Petals broadly oblong, sessile, of a thick, glossy substance and bright crimson colour, 
thrice as long as the calyx, ciliolate. Capsule deeply 5-lobed, almost resolved into 
5 follicles.

Flowers perfect, small, regular. Calyw-tube connate with the ovary, 
or very rarely free ; limb 5- rarely 4-cleft, imbricate. Petals 5 (or 4), 
free or cohering into a monopetalous, epigynous, or perigynous corolla, 
imbricate in estivation. Stamens as many as the petals and alternate 
with them ; filaments free or adnate to the base of the petals ; anthers 
erect or incumbent, 2-celled, introrse, opening by slits. Ovary more or 
less inferior, rarely free, 1-3- rarely 5-celled ; ovules pendulous, solitary, 
or two collateral ones in each cell, very rarely (in Z’hamnea) about 10 ; 
styles 23, distinct or more or less connate. Fruit dry, indehiscent or 
capsular, mostly dicoccous and crowned by the calyx-limb. Seeds with 
copious albumen ; embryo minute, straight, next the hilum. 
Heathlike shrubs and suffrutices, all natives of South Africa. Leaves small, gla- 
brous or hairy, acerose, rarely ovate, very entire, sessile or subsessile, crowded and 
mostly imbricated, with a discoloured or withered, callous tip (ustulate). Stipules 
none. Flowers minute and white, —— oa ae ean or capitate, rarely soli- 
tary and axillary. This Order is closely re to ifragacece on the one 
bat FS Hamamelidee on the other. The habit is peculiar. sas ea
