250 de Frame . — The Morphology and Anatomy of the 
measured over 48 cm. in diameter. One of these latter bore no less than 
forty-two independent scapes, at the base of each of which there were from 
3 to 5 winter buds developed in the axils of withered leaves. Thus, poten- 
tially, there were well over 120 shoots of the season following. 
As in .S', binervosa the inflorescences are terminal in position. 
The scape . The scapes are scabrid-pulverulent throughout. They are 
richly branched from near the base, but only the apical branches are fertile. 
The main axis of the scape is usually prostrate, the lateral branches ascend- 
ing divergent and not approximating to one plane. 
The scale leaves are acute, membranous, brown, or lower foliaceous. 
The spikelets are more or less imbricated, with from 1 to 2 flowers. 
The interval between successive spikelets on the same side usually to § 
the length of the spikelet. 
Flowering period. J uly. 
Flowers. Pale pinkish purple, from 3 to 4 mm. in diameter. Petals 
usually entire, blunt or very slightly emarginate. Midrib coloured as blade 
or a very little darker. 
Anthers yellow. 
Calyx (Text-fig. 3). Usually about 3 to 4 mm. long, with nointermediate 
teeth. Calyx segments acute with deep purple ribs. All the ribs usually 
hairy. Long hairs present between the ribs, especially at the base of 
the intercostal sinuses. 
Outer bract. Membranous ovate, obtuse or abruptly acute, with a 
prominent brown vein from 1-2 to 2 mm. long. Usually about 1*5 mm. 
(Text-fig. 4, a, top row). 
Middle bract. Membranous, asymmetrical, obovate, usually bifid, with 
two unequal veins. Usually 2 to 3 mm. long (Text-fig. 4, b). 
Inner bract. Obtuse obovate or faintly bilobed, with a broad mem- 
branous margin above the middle. The brown opaque portion seldom 
extending to the apex as a dark line from 3 to 3*8 mm. long (Text- fig. 4,6'). 
Bracteolc. Membranous, oblong, asymmetrical, 2 to 3 mm. long (Text- 
fig. 4, d). 
Seed. Lanceolate, smooth, brown, about 1 -5 mm. long. 
III. Anatomy. 
The order Plumbagineae has been the subject of much anatomical 
investigation, which has, however, been directed more particularly to- 
wards the anomalous structural features of the axis found in the genera 
Acantholimo]i and Aegialitis, and in the investigation of the epidermal 
glands which occur throughout the order. So far as it has been possible 
to ascertain, no examination of the anatomy of the Siatice binervosa has 
been previously undertaken, and, with the exception of a brief description
