8 Ewart, White and Rees : 



tudinally by two valves. Stamens opposite segments of perianth, 

 filaments apparently curved in bud, and attached to central disc. 

 Disc small and quadrilateral, 4-partite. 



Female flower — solitary and axillary. Perianth persistent, 4 

 segments in two whorls. Each segment with wide base and 

 narrow, pointed tip ; two outer smaller and somewhat refiexed. 

 Ovary — 2 carpels and 2 tongue-like stigmas, thick, fleshy, 

 diverging. 



Fruit oblong, 2-celled capsule with persistent perianth. One 

 seed in each cell, oblong, smooth, with caruncle. Embryo 

 green, straight, linear, cotyledons slightly longer and about 

 same width as radicle. 



Allenia Blackiana, Ewart and Rees. 



(MiCRANTHEUM DEMISSUM, F. V. M.). 



Small heath-like shrubs. Leaves on very short petioles, 

 small, entire linear, coriaceous, in alternate twos or threes, hairy

Mount Compass, Kangaroo Island, Nov., 1908, J. M. Black. 



The type form has the leaves glabrous or slightly hairy,

Var. MiCROPHYLLA, n. var. 



Small, rigid, much branched shrub. Leaves very small, J inch 

 long, hairy, capsule oblong, rather shorter, and covered with 

 hairs.

Specimens of the plant were forwarded by J. M. Black, who 

 pointed out that if they were Mueller's Micrantheum demissum 

 the numbers of parts in the flower and fruit differed from that 

 proper to the genus Micrantheum. This was found to apply 

 to all the specimens, and hence it became necessary to raise a 

 new genus Allenia, distinguished from Micrantheum and Pseu- 

 dant/ius, by the perianth four-partite instead of six-])artite, by 

 the four instead or 3, 6 or more stamens, and by the 2-celled
