 oblong, 3-lobed at the apex ; flowers terminal, capitate, sessile. 

 Tj . G. Native of New Holland, on the western coast. 



Capitate-flowered Bauera. Shrub. 



Cult. The species of this genus are very pretty little shrubs, 

 which flower nearly the whole year through ; they are therefore 



very desirable plants for a greenhouse or conservatory. They 

 are rather hardy, and easily cultivated. An equal mixture of 

 sandy loam and peat is the best soil for them ; and young cut- 

 tings root freely in the same kind of soil, under a bell glass.

ORDER CXXI. GALACrNJi (plants agreeing with Galax 

 in important characters). D. Don, in edinb. phil. journ. Oct. 

 1828. Francoacese, Adr. de Juss. in ann. des scien. vol. 25. 

 p. 7. 



Calyx 4-5-parted, permanent. Petals 4-5, hypogynous, cadu- 

 cous, alternating with the calycine segments; stamens 8-10-16, 

 hypogynous, joined into a tube, which is toothed at the apex, or 

 distinct ; filaments or alternate teeth antheriferous. Ovarium com- 

 posed of 3 or 4 follicles, which are joined, therefore 3-4-celled ; 

 ovula indefinite ; stigma composed of 3-4 joined ones, undivided 

 or 4-lobed. Capsule 3-4-celled, 3-4-valved ; valves bearing the 

 dissepiments in the middle. Central placenta none. Seeds nu- 

 merous, minute, scobiform, inserted in the inner angle of the 

 cells ; outer testa loose, membranous, cellular : inner one very 

 thin, closely adhering to the albumen. Albumen copious, fleshy. 

 Embryo erect, terete, with short cotyledons, and a long cylin- 

 drical centripetal radicle. Perennial American herbs. Leaves 

 radical, simple, lyrate, pinnatifid or serrated ; the teeth tip- 

 ped each by a gland. Flowers terminal, copious, disposed 

 in spicate racemes ; pedicels 1 -flowered, propped each by a per- 

 manent bracteole. 



This order differs from Saxifragciceceby the presence of sterile 

 stamens, alternating with the fertile ones ; in the absence of a 

 central placenta ; and in the frequent quaternary arrangement, 

 in the parts of the calyx and corolla.
