Order XV. BRUNIACEa®. 
Bruniace.®, R. Brown in Abel's China, (1818) ; DC. Prodr. 2. 43. (1825) ; Ad. Brong- 
niartin Ann. des Sc. Nat. (1826). 
Essential Character. — Calyx superior, 5 -cleft, imbricated, occasionally nearly infe- 
rior. Petals alternate with the segments of the calyx, arising from its throat, imbricated. 
Stamens alternate with the petals, arising from the same point, or from a disk surrounding 
the ovary ; anthers turned outwards, 2-celled, bursting longitudinally. Ovai-y half inferior, 
with from 1 to 3 cells, in each of which there is from 1 to 2 suspended collateral ovules ; 
sometimes 1 -celled from the abortion of carpels, or that of the dissepiments ; style simple or 
bifid; stigma simple. Fruit dicoccous or indehiscent, 2- or 1 -celled, crowned by the per- 
sistent calyx. Seeds solitary or in pairs, suspended, sometimes with a short aril ; albumen 
fleshy ; embryo minute at the base of the seed, with a conical radicle, and short fleshy coty- 
ledons. — Branched, heath-like shrubs. Leaves small, imbricated, rigid, entire, with a cal- 
lous point. Flowers small, capitate, or panicled, or even terminal, and solitary ; either 
naked, or with large involucrating bracts. 
Anomalies. Berzelia has a single carpel. Raspailia has the ovary superior. 
Affinities. These appear to be most immediate with the last order, which 
see. Moesslera (which is Tittmannia of Brong.) has an ovary which seems in 
a state of transition to Grossulaceae. According to Brown, the order is nearly 
aUied to Hamamelaceae, which are known by their habit, stipules, and deciduous 
valves of the anthers, and also by their valvate sepals and petals. Brongniart 
indicates an affinity with Myi'tacese through Imbricaria, which is very nearly 
constructed as true Bruniaceae, but has the stamens opposite the petals, and 
dotted leaves. He also considers that Comacese bear them much real affinity, 
and he even contrasts them with Umbelliferae, to which they no doubt approxi- 
mate very nearly. The genus Raspaiha is remarkable for having the stamens 
arising from the top of a superior ovary ! and Thamnea is perhaps a solitary 
instance of a 1 -celled ovary with the ovules adhering to a central columnar axis. 
Geography. All found at the Cape of Good Hope, with the exception of 
a single species inhabiting Madagascar.

Essential Character. — Anthers bursting by recurved valves. 
This simple character is so remarkable that it seems in aU cases, as far as 
we at present know, to form of itself an important mark of distinction. It may 
however prove, as many another has already proved, less valuable than is sup-
