Flowers lateral on the branchlets. 



Males solitary or fascicled : calyx absent, but replaced by a cupular 

 membranous unequally four-lobed involucel : corolla bell-shaped, four- 

 partite. 



Females solitary or loosely aggregated ; calyx adnate to the ovary, 

 tubular, limb shortly 4- or 5 -toothed ; corolla tubular below, 4-partite, the 

 lobes recurved ; styles rather slender. 



Drupe rounded-oblong, \ hich long, pale yellow when ripe. 



Hob. Dunedin, mostly in woods. 



In woods this species resembles in foliage and habit C. rotundifolia, A. 

 Cunn. In open situations the leaves are always much reduced in size, and 

 are of a darker hue. Many twigs are in the latter situations almost desti- 

 tute of leaves, but produce a profusion of flowers. The prevailing forms in 

 open situations are of a much more decided divaricating habit than the lax 

 forms occurring in shady situations. 



I think the species has hitherto been confounded with G. rotundifolia, A. 

 Cunn. ; but its berry is never didymous and the bark and foliage are differ- 

 ent. Some of the forms appear also to have been included in the group of 

 species and varieties that goes by the name of C. divaricata, A. Cunn. 

 Lepidium kawarau, n. sp. 



An erect much-branched leafy species, 5-12 inches high, dioecious, 

 glabrous or with sparse whitish hairs. 



Eadical leaves numerous, 3-5 niches long, primatisect, on short flat 

 petioles, the segments distant linear lobed above and rarely below also. 



Lower cauline leaves similar to the radical but smaller, passing gradually 

 into linear, sessile toothed or entire forms towards the top. 



Eacemes terminal ; flowers imperfect, minute, on short slender pedicels. 



Males somewhat larger than the females, with four small petals and a 

 mere rudiment of an ovary without style or stigma. 



Females usually apetalous and with rudimentary stamens. 



Pods ovate-orbicular, -| inch long, emarginate ; style distinct. 



Hob. Kawarau Eiver, near Victoria Bridge, Cromwell; "Earthquakes," 

 near Duntroon. The Duntroon forms are almost pubescent. 



This species has been erroneously included by Mr. T. Kirk, F.L.S., in 

 his Lepidium australe, which he describes as having perfect flowers. My 

 species is, however, dioecious. The error has no doubt arisen from the very 

 imperfect condition of the specimens I was possessed of when his Eeview of 

 the New Zealand Lejridia was being prepared. Since then I have procured 

 excellent specimens, and have grown the Duntroon form in my garden. 

 The seedlings of the Kawarau form have all been male, and have borne no 

 fruit.
