CXL. RESTIACE^. 415 



S. HYPOLJENA, E. Br. 



Male and female spikelet« dissimilar. — Males numerous, 

 mauy-flowered, small, in spikes or panicles. — Females few, 1- 

 flowered, spieate. Perianth of G unequal or nearly equal 

 glumes in 2 rows. Ovary sessile, 1-celled ; style 2-3-parted. 

 Fruit ovoid or subglobose, bony, indehiscent, often surmounted 

 by a thickened yellow disk or stylopod, 1-celled, 1-seeded. 

 — Sheaths of culm persistent. — Kuntli, I.e. p. 451. 



The male plants resemble Restio, the females Hi/jyodiscus in aspect ; from 

 tlio first they differ in the fruit, and fi'om the latter in the sessile fruit, ab- 

 sence of disk, etc. — 10 species, besides a few others, natives of Australia, 

 Tasmania, etc. 



9. ELEGIA, Thunb. 



Male and female spikelets nearly of the same size and form, 

 arranged in rather loose panicles, l-flowered. Flowers com- 

 pressed or triangular. Perianth of 6 glumes in 2 ijows, in the 

 male flowers the outer glumes shortest. Ovary 1-celled by 

 abortion; styles 3, rarely 2. Fruit triangular, rarely pyri- 

 form or compressed, 1-celled, l-seeded, indehiscent. — Sheaths 

 of culm deciduous, rarely persistent (E. deusta). — Kunth, I. c. 

 p. 460. 



Readily distinguished from its allies by its deciduous sheaths, panicled 

 inflorescence, and indehiscent, 1-celled fruit. The latter characters sepa- 

 rate it from Dovea. — 13 species, all South African. 



10. WILLDENOVIA, Thunb. 



Male and female spikelets considerably difterent in size and 

 form ; males many-flowered, small, numerous, in loose panicles. 

 — Male flowers : Bracts and glumes linear, membranous. — 

 Female spikelets large, solitary, rarely 2 ; bracts coriaceous, 

 rigid. Flowers solitar}'-, terminal, on a thickened, spongy, (3- 

 lobed pedicel. Perianth of 6 nearly equal hyaline glumes in 

 2 rows. Ovary 1-celled; stigmas 2, rarely 3. Fruit stipi- 

 tate, cylindrical, horny, indehiscent, 1-celled, 1-seeded. — 

 Sheaths of culm persistent. — Kunth, /. c. p. 452. Nematanthus, 

 JVees ; Kunth, I.e. p. 452. 



The female plants are closely allied to Hypodiscus, but the male inflores- 

 cence is different, and more hke that of Ceratocarytim. — 8 species, all Soutli 

 African. 



11. CERATOCARYUM, Nees ab Eseub. 



Male and female inflorescence dissimilar. — Male thyrsoid, 

 bracts and glumes linear-lanceolate, membranous, inner glumes 

 shortish. — Female spikelets 2-3, spieate. Flowers solitary, 

 terminal. Perianth sessile, minute, hyaline, of G glumes in 2 

 rows, the inner row smallest. C)vary . . . Fruit sessile, bony.
