A short central axis gives off much-branched axillary shoots, 

 which result finally in a cushion -shaped plant covered with con- 

 spicuous bright yellow flowers. In a description on the sheet in 

 Dr. Bolus' herbarium the plant is called a stunted sub-shrub. 

 The plant is provided with mycorrhiza and has short thick roots. 

 In connection with the occurrence of mycorrhiza in this species 

 and possibly also in Exochaenium, attention may be drawn to the 

 cases of Obolaria and Bartonia described by Holm in Ann. Bot. 

 xi., 369, and xx., 441. The first two or three pairs of leaves are 

 very small, as in Exochaenium, whilst the upper two or three 

 pairs, and the numerous bracts, which are indistinguishable from 

 the leaves, are relatively large. According to the label on 

 Barber's specimen, No. 21, this species is found "studding the 

 flats in places where water occasionally lodges." 



As regards the position of the anthers, this plant belongs to the 

 Belmontia section of the genus Sebaea, and the stigma, with its 

 large biglandular swelling, is also like that found in the genus. 

 The long tubular and slightly inflated calyx, and the elongate 

 linear-lanceolate leaves separate this plant from all others, and 

 perhaps constitute characters of generic value. Should it be 

 found after further field work that it is desirable to raise this 

 plant to generic rank it would also become necessary to restore 

 the genus Lagenias, whose relationships to Sebaea are of a 

 character very similar to those between this genus and S. 

 Gompacta.
