138 THE FLORA OF THE NOETHEEN TEERITOEY. 



1. J. anomala, Ewart and Morrison. — Upper lobes of calyx shorter than 

 lower, connate to top, petals somewhat shorter than calyx, standard small, 

 shorter than the other petals, pod subglobose with two seeds. Flowers small 

 situated on base of dichotomous, striate, leafless stems, with broad scarious 

 bracts and bracteoles. A small undershrub reaching 1 ft. in height, with numer- 

 ous stems repeatedly forked from the base ; bran(5hes flattened angular, 

 striate, not pungent, at first thinly pubescent, 1.5 mm. broad ; leaves repre- 

 sented by small brown lanceolate scales at nodes. Mowers very shortly pedi- 

 cellate on short dense nearly sessile racemes clustered on basal rounded por- 

 tions of branches, each subtended by a suborbicular brown villous bract, with 

 a pair of oblong ovate muoronate bracteoles at base of calyx, in both cases 

 5 mm. in length, and persisting. Calyx densely silky villous, cleft to near base, 

 lower lobes 9 mm. oblong-Unear and acuminate, connate to top and forming a 

 broad ovate lip 7-8 mm. long, with a subulate bifid tip. Petals and pod firmly 

 -clasped by calyx, standard broadly ovate, on a very short broad claw, about 

 5 mm. in length, and fitting under the concave upper lip of the calyx, wings 

 on a very slender claw, narrow oblong, of about the same length as keel, but 

 with a transverse fold near top, keel nearly 8 mm. long, ovate lanceolate. Pod 

 ovoid or subglobose, sessile, villous, 1 cm. long, including the straight and 

 tapering acuminate beak, which is nearly as long as the pod itself, and exceeds 

 the calyx ; seeds two, approximately reniform, smooth, brown, 2 mm. in 

 length.

This plant shows affinities to some of the Brachysemas, particularly the 

 xerophytic species of the section Leptosema, in the leafless condition, radical 

 inflorescence, broad bracteoles (as in B. bracteolosum), connate upper calyx 

 lobes, and small ovate standard ; but it differs in the small number of seeds in 

 the pod, and in the size and colour of the flowers. Compared with Jacksonias, 

 on the other hand, it agrees in having small flowers, with the upper calyx lobes 

 shorter than the lower, petals yellow, nearly equal in length, and shorter than 

 the calyx. The seeds in the pod are only two, which is the usual number in 

 Jacksonia, and if we consider that the leafless condition is normal in that genus, 

 while exceptional in Brachysema, there need be no hesitation in deciding its 

 generic position. There is seen in this species a considerable resemblance to 

 some of the smaller forms of the Scoparia section found in extra-tropical South- 

 west Australia, and its mature calyx even shows the angular character noted 

 in the buds of J. angulata and others.
