ttcally compressed ; sori dorsal ; fronds 

 rigid. 

 § Trichomaninew—Rmg and spore-cases 

 as in Gleichenincm ; sori extrorse-mar- 

 ginal ; fronds pellucid. 

 § Schizceinem— Ring apical, complete, 

 horizontally transverse ; spore-cases 

 sessile or subsessile, oval, crowned by 

 the convergent striae of the ring, 

 sometimes resupinate. 

 § Ceratopteridinece— Ring rudimentary or 

 more or less incomplete, very broad, 

 flat, obliquely-vertical ; spore-cases 

 sessile, globose. 

 § Osmundinece — Spore-cases vertically 

 two-valved; ring rudimentary, trans- 

 verse. 

 The Polypodinece are further divided into 

 lesser groups characterised by the form, 

 position, and vestiture of the sori. There 

 is little difference of opinion amongst 

 pteridologists as to the three principal 

 divisions, but a good deal of diversity as to 

 the value of the minor ones. [T. M.]

 Scirpece, having the inflorescence in spikes, 

 solitary, in pairs, or in crowded heads, 

 many-flowered; scales imbricated allround, 

 the lower larger, one or two of them

FINCKEA. A genus of the heathworts, 

 having the corolla cylindrical and tubular, 

 with a four-toothed border. The name was 

 given by Klotzsch in honour of a botanist 

 named Finck. The species are Cape shrubs, 

 the leaves three or four together and 

 hairy ; corolla hairy and about as long as 

 the calyx. [G. D.]

 belonging to the tribe Phalaridew. Glumes 

 two, equal, with bristly points, keeled and 

 membranaceous ; lower flowers fertile, as 

 long as the glumes ; pales rigid, the lower 

 rather the longest, keeled, with a short 

 bristle at the point, five to seven nerved, 

 the upper shorter and slightly compressed; 

 stamens three, with bearded anthers ; styles 

 two ; upper flowers imperfect. Only two 

 species are described, both of which are 

 natives of South Africa. [D. M.] 



FIN HOUSSY. (Fr.) Trifolium repens. 



FINLAYSONIA. A genus of 

 dacece, containing a single species, native 

 of India. It is a twining glabrous plant, 

 yielding a milky juice, and having oppo- 

 site obovate leaves, and numerous small 

 flowers arranged in interpetiolar corymbs. 

 The calyx is small, five-cleft; and the 

 corolla rotate. The staminal crown, which 

 rises from the throat consists of five deli- 

 cate white slightly converging threads, 

 each bent back at the apex so as to form 

 a small hook ; the stamens are distinct, 

 with short filaments, and large anthers 

 adheringto the stigma; and the divaricate 

 follicles contain numerous large flat obo- 

 vate seeds with a few silky fibres. [W. C]

 containing about ten species from the 

 West Indies and Central America. They 

 are twining hairy shrubs, with opposite 

 cordate leaves, and many flower§ in ra- 

 cemes on long interpetiolar peduncles, 

 which thicken upwards and are scarred by 

 the deciduous pedicels. The calyx is five- 

 parted ; the corolla is rotate and five-cleft,
