the latter is sharply prominent. Sheaths much flattened, with sharp E.mooth keels, nearly half 

 as long as the lamina. Panicle shorter than the leaves, peduncle flattened, with one or two of 

 the last leaves reduced to erect sheathing bracts. Flowers deep blue, in a few dense sessile 

 cymes, shortly pedicellate, the buds nearly globular, when expanded about Jin. in diameter. 

 Bracts scarious, brown, ovate-acuminate, small, 1 to 2 lines long. In all the flowers opened 

 most or all the organs of reproduction were metamorphosed into petaloid bodies. 



Hab.: Southport, H, Schneider. On the sea coast sand, amongst the bushes just above 

 high-waler mark. 



The above plant is, I think, identical with Dr. Brown's one from Torres Straits, but neither 

 Brown, in Prod., nor Baker, in Journ. Linn. Soo., describes the flowers. Benlham, in Flora 

 Anstr. vii., 16, says that: "The inflorescence in the specimen preserved is scarcely fully 

 developed and almost destroyed by insects." 



I have a specimen gathered by li. C. Burton, near Northcote, a few years ago, which has also 

 double flowers, but in nothing else differs from D. Icevis, E. Br. 



4. I>, ensifolia (sword-like leaves), Bed, Lil. t. 1 ; Bentli. Fl. Auttr. vii. IG. .^ 

 Very near the broad-leaved forms of D. caridea, with the stems similarly leafy in n 

 the lower part and the sheaths acutely keeled, but the blades usually much 

 broader, varying from I to lin. in breadth and the sheaths shorter and looser. 

 Panicle of D. cm-ulea. Perianth-segments fully 4 lines long. Filaments shorter 

 than the anthers, the thickened part very short and as broad as the anthers 

 themselves. Fruit nearly globular, larger than in D. canuleci. — Baker in Journ. 

 Linn. Soc. xiv. 57G ; Bot. Mag. t. 1404 ; D. nemorosa, Jacq. Hort. Schoenbr. t. 94. 



Hab.: This, the common sprcies in tropical Asia and in the Mascareue and Pacific Islands, 

 is represented in Australia at Bookingham Bay, and is precisely similar to some from China and 

 the Philippine Islands.

(Eeferring to the tuft of tow under the anther.) 



Perianth withering after flowering but not twisted, and at length deciduous, of 

 6 spreading segments usually 5-nerved, all equal and entire or the inner ones 

 broader. Stamens G, hypogynous; much shorter than the perianth ; filaments either 

 filiform and fiexuose at the base with a dense woolly tuft under the anther, or 

 shortly tomentose-wooUy from the base ; anthers oblong, very much rolled back 

 after shedding the pollen. Ovary sessile, 3-celled, with several ovules in each 

 cell ; style filiform, undivided. Capsule ovoid or oblong, 8-valved. Seeds 

 several (3 to 6) in each cell, ovate, more or less flattened, with a black smooth 

 crustaceous testa, opaque or shining. — Perennials with fibrous roots. Stems 

 erect or ascending, simple below the inflorescence or branched and sometimes 

 woody at the base. Leaves either all radical or distichously spreading on 

 the stem. Flowers blue, in a very loose terminal dichotomous cyme. Pedicels 

 filiform, often 2 or 3 together and terminal or solitary along the branches. 

 Bracts minute or none, or the lower ones leaf-like in the leafy species. 



The genu3 is limited to Australia. 



Stem leafy to the inflorescence, often branched at the base and sometimes 



woody 1. S. (jlauca. 



Stems leafless except at the base. Leaves linear, in dense radical tufts, 

 very rigid, IJ to 3 lines broad. Flosvers blue or yellowish, very 

 rarely white . . . . 2. ,S. ccespitosa, 



1. S. glauca (grey), B. Br. Prod. i79 ; Benth. Fl. Austr. vii. 53.— A leafy 

 perennial with stems on a creeping rhizome sometimes low and tufted, or weak 

 and ascending, under 1ft. high, sometimes 2 or 3ft. high, wooJy and branched at 

 the base. Leaves distichous, the sheaths usually concealing the stem, somewhat 

 flattened with an acute keel, or almost terete, the blade erect or spreading, linear 

 or lanceolate, usually 3 to 4in. long, but sometimes twice that length and 

 varying from 2 to 4 lines in breadth. Flowers in a loose terminal dichotomous 

 cyme usually leafy at the base, the branches very spreading, the filiform pedicels 

 recurved, varying from i- in lin long, mostly solitary but sometimes 2 together
