papillose and stigmatic. The ovary is single and contains 
a single anatropous ovule. Cowcowing, W.A, 1904, M.

Salicornia Lylei, Hwart and White, 1. sp. (Salsolacez). 
After Professor Lyle. 
An undershrub from 14 to 25 feet high, very much 
branched, the branches being woody and greyish in colour. 
The smaller branches are conspicuously longitudinally 
ribbed. The segments are dilated and concave at the top, 
with opposite projections arranged in a decussate manner. 
The average length of each segment is about 3 mm. and of 
each free projection about "8mm. ‘The length of the fertile 
segments is about 2mm. On each flowering spike there 
are from 8 to 12 fertile segments, each bearing a whorl of 
6 flowers, with projecting styles and anthers. Hach flower 
consists of a single stamen and carpel, the filament and 
ovary being surrounded by the somewhat fleshy perianth, 
which has a prominent marginal ridge, and a narrow open- 
ing at the top continued along the ventral side of the flower, 
through which, at the top, the stamen and style project. 
The anther is relatively large, two-lobed and nearly 
spherical, about ‘5 mm. in diameter, and dehisces loculi- 
cidally; the filaments are 1 mm. in length. The style has 
papillose, brown, stigmatic surfaces; as arule there are 
two branches, but occasionally three. The ovary is rela- 
tively large and hollow, and contains a single anatropous 
ovule, whose funicle is attached to the axis of the spike. 
Six fruits are developed in each whorl and they are sur- 
rounded by the persistent, fleshy perianth; the styles also 
are persistent. The ovary is swollen and contains one seed 
attached to a long stalk. The fruits of successive whorls 
are alternately arranged. Cowcowing, near Salt Lakes, 
W.A., 1904; M. Koch, No. 1051.
