GKAMINELiE. 
36. Sclerochloa Pal de Beauv. 
* Glumes ivith 3 ribs. 
1. S. mariiima (Lindl.) ; panicle branched : lowermost branches 
in pairs, or simple, branches ultimately erect, spikelets linear ad- 
pressed 4 — 8-flowered, rachis terete, outer palea obtuse apiculate : 
midrib not reaching to the apex, root stoloniferous. — Glyceria Sm. 
E.B. 1140. R. 1611, 1612. Par. 42.— Root fibrous with rooting 
or ascending scions. L. involute. Outer palea with involute 
margins. Ligule bluntish. I do not find a furrow on one side 
of the rachis according to Fries's description, and fear that the 
characters derived from that part are not'so constant as he sup- 
poses. — Sea-coast, in damp places. P. VI. VII. 
2. S. distans (Bab.) ; panicle branched, branches elongated 
ultimately spreading or defiexed lowermost in fours or fives, 
spikelets linear 3 — 6-flowered, rachis semiterete rather flat on 
one side, outer palea obtuse : midrib not reaching to the apex, root 
fibrous.— Ghjceria Sm. E. B. 986. R. 1609. Par. 41.— Root 
fibrous, without rooting scions. St. decumbent below. L. flat 
short. Ligule short and blunt, Margins of the outer palea not 
involute. Spikelets and fl. half the size of those of the preceding. 
" L. with 7 prominent rough ribs which are not found in G. ma- 
ritima." IV. Wilson.-— In inland situations the panicle becomes 
much more compact, the fl. more numerous, and the whole plant 
puts on a very different appearance but has no distinctive cha- 
racter. — Sandy sea-shores and in Leicestershire. P. VI. — VIII. 
3. S. Borreri (Bab.) ; panicle branched, branches ultimately 
erecto-patent lowermost generally in fours, spikelets linear of 
about 4 fl., rachis terete, outer palea u-ith a rigid apiculus formed 
by the extremity of the dorsal nerre, root casspitose. — Glyceria 
E. B. S. 2797 — St. 6—12 in. high. L. short, flat, with very 
long sheaths. Ligule blunt. Margins of the outer palea not 
involute. Spikelets and fl. half the size of those of S. maritima. 
Branches of the panicle short, scarcely elongated after flowering, 
hispid. — Glyceria conferta (Fries) is probably this plant. — Muddy 
salt marshes. P. VI. E. 
4. S. procumbens (Beauv.) ; panicle ovate-lanceolate compact 
distichous rigid, spikelets linear-lanceolate of about 4 fl., rachis 
terete angular, outer palea obtuse with an apiculus formed by 
the extremity of the dorsal nerve, root fibrous. — Glyceria Sm. 
E. B. 532. R. 1517. Par. 42.— St. procumbent, rigid. L. flat, 
with inflated sheaths. Panicle about 2 in. long, with very short 
rigid branches spreading in 2 rows. Fl. large. — Salt marshes.
