long. The stipules measure 1-2 to 1*8 cm. in length. The species 

 is apparently very near to B. retrofracta.

The most nearly related species is said to be B. subsessilis, 

 the distinguishing features being the leaf-shape and the indu- 

 mentum of the younger parts. 



NEW AND BARE WEST AUSTRALIAN PLANTS.

Calandrinia schistorhiza, n. sp. Radice tuberoso, foliis 

 omnibus radicalibus, scapis nudis unifloris, staminibus numerosis, 

 styli ramis 3, ovulis numerosis. 



Dwarf plant with tuft or rosette of leaves seated on the upper 

 end of the tuberous root, which is forked or irregularly divided 

 into several lobes or branches, usually tapering. downwards to a 

 point from which the fibres are continued. Leaves all radical, 

 fleshy, about 1-5 cm. long, with a broad obovate lamina on a petiole 

 twice as long. Scapes up to seventeen in number, simple, leafless, 

 flexuose, 3-4 cm. long, each bearing one large flower at its summit ; 

 bracts in two or three pairs, or verticils of three, at the nodes — 

 exceptionally, four pairs with a pair of flowers in the uppermost — 

 broadly ovate with a short acuminate often recurved point. Pedicels 

 7 mm. long, dilated at the top, buds acutely pointed; sepals orbi- 

 cular, thin, about 5 mm. diam.; petals five rather more than twice 

 as long as sepals, broad, pink ; stamens numerous, anthers oblong ; 

 style divided to near the base into three long, linear, stigmatic 

 branches, ovary subglobose, much shorter than sepals in expanded 

 flower, ovules numerous. 



Boulder, Sept. ; W. D. Campbell. 



In affinity this plant is very close to C. primuliflora Diels, 

 agreeing with it in most of the essential characters, excepting the 

 short union of the style-branches at the base, as in G. Lehmanni, 

 and the smaller number of pairs of bracteoles on the scapes. It 

 is, however, a coarser plant, with the leaves and flower-scapes, as 

 a rule, in direct contiguity with the upper end of the tuber, although 

 sometimes the upper part of the root is narrow for a short distance 

 downward, then expands into the more fleshy tuberous portion ; 

 but in both of the species referred to the tuberous condition is due 

 merely to an accumulation of succulent tissue round the fibres of 

 the root, which are opened out in the bulbous part, and continue 

 as fibrous threads on emerging at the lower end. The branched 

 condition and rough surface of the tuber of the Boulder plant, 

 with the absence in most specimens of the "rootstock" or 

 "rhizome," offer a strong contrast with the underground portion 

 of C. primuliflora ; but the similarity in structure of the floral 

 organs suggests a query as to whether a difference in the 

 constitution of the soil, such as the presence of salt, might
