The perianth is bell-shaped or ventri cose, | 

 with the three outer segments about half | 

 as large as the inner ones ; and there are j 

 six stamens inserted in the base of the 

 perianth, and a three-cornered ovary sur- I 

 mounted by three sessile stigmas. C. lu- j 

 teus grows about a foot high, and has 

 oblong bulbs, long linear leek-like leaves, i 

 and two or three terminal yellow flowers, | 

 the divisions of which are scarcely con- 

 nected at the base, the three exterior ones, 

 which are smaller, greenish on the outer 

 side, the three broade/ inner ones being 

 bearded with purple hairs; the stem is 

 bulbiferous in the leaf axils. C: purpurea 

 is a more showy plant, growing two feet 

 high, with the lower leaves elongately- 

 linear, and the upper ones broader and 

 more lanceolate ; these also bear numerous 

 little bulbs in their axils. The stem pro- 

 duces about three flowers, two from the 

 point, and one from a side branch ; these 

 are large, with the sepals green marked 

 with purple outside and yellow within, and 

 the petaline segments brownish-purple 

 outside, yellow within, and ciliated ; the 

 nectariferous pit is spade-shaped. [T. MJ 



CYCLODIUM. A genus of polypodia- 

 ceous ferns belonging to the Aspidiece. 

 They are distinguished by having pinnate 

 veins from a central costa, these producing 

 connivently anastomosing venules, which 

 form arcuate or angulate areoles. The 

 sori, which are globose, are covered by pel- 

 tate indusia. The species are thick-frond- 

 ed robust pinnate ferns, with the fertile 

 fronds more or less contracted, and some- 

 times so much so that the sori almost cover 

 the surface. There are two or three closely 

 allied species found in South America, and 

 one in the Philippine Islands. [T. M.] 



CTCLOGYXE. A genus of LeguminoscB 

 found in Western Australia, the chief dis- 

 tinguishing character of which is found in 

 the style, which is coiled inwards at the 

 point, and much bearded. C. canescens, the 

 only species known, is an astragalus-like 

 bush with unequally pinnate leaves and 

 leafy stipules ; the leaflets (thirteen or 

 fifteen in number) being small, oboval, 

 smooth above, and clad underneath with 

 white hairs. The white appearance these 

 hairs give to the plant, together with the 

 profusion of purple flowers, render it an 

 attractive object. The flowers are disposed 

 in erect racemes, and have a bell-shaped 

 five-toothed calyx ; a nearly round stan- 

 dard, with a green blotch at its base, two 

 short wing petals, and a keel longer than 

 the wings. The inflated oblong pods con- 

 tain a number of seeds. [A A. B.] 



CYCLOMYCES. A curious genus of hy- 

 menomycetous Fungi, allied to Polyporus, 

 in which the walls of the pores form gills 

 concentric with the stem or with the bor- 

 der of the pileus. The species originally 

 described was gathered in Mauritius, but 

 another occurs in North America, and a 

 third has been found in the Sikkim Hima- 

 laya. [M. J. B.] 

 CYCLOPELTIS. A name applied to two 



pinnate aspidiaceous ferns, with peltate 

 indusia and free veins, now referred to 

 Polystichum. [T. MJ 



CYCLOPHORUS. A name given by Des- 

 vaux to a group of polypodiaceous ferns, 

 subsequently called Niphubolus by Kaulf uss, 

 on the ground that Desvaux's name was in 

 use among conchologists. Niphobolus has 

 been generally adopted. [T. M.] 



CYCLOPIA. A genus of dark-coloured 

 South African bushes of -the leguminous 

 order, belonging to that group of the family 

 in which the filaments of the stamens are 

 quite free. They may be recognised from 

 their allies by having a circular depression 

 at the base of the calyx, round the pedicel. 

 The leaves are sessile and made up of three 

 generally linear smooth or pubescent, leaf- 

 lets, which often have their margins rolled 

 backwards. Their bright yellow broom- 

 like flowers are generally produced in great 

 profusion from the axils of the upper leaves, 

 and have their stalks always furnished 

 with two boat-shaped bracts. The pods 

 are oblong, compressed, and contain a num- 

 ber of seeds. C. genistoicles, a plant some- 

 times seen in greenhouses, has smooth 

 linear leaflets strongly-recurved at the 

 margin, and pretty yellow broom-like 

 flowers. The leaflets of this plant are used 

 at the Cape in infusion or decoction for 

 promoting expectoration in chronic catarrh 

 and consumption. It is called Bush Tea, 

 and has an agreeable tea-like smell, with a 

 sweet astringent taste. [A. A. BJ 



CYCLOSIS. A supposed motion of fluids, 

 occurring in the kind of tissue called cinen- 

 chyma. 



CYCXOCHES. A singular genus of or- 

 chids, with the habit of Catasetum. The 

 name, which signifies Swan-neck, was sug- 

 gested by the long curved column which 

 in the original species rose gracefully from 

 a broad convex lip. The character of the 

 column is proper to all the species, but the 

 lip varies from a broad solid oval plate to a 

 stalked disk whose margin is broken up 

 into numerous glandular rays. And, what 

 is most strange, the same stalk bears flowers 

 of both kinds, with others intermediate 

 between the two. Here, therefore, we have 

 a repetition of the singular variations al- 

 ready described in Catasetum. Upon this 

 tiie Editor of Paxton's Floiver Garden makes 

 the following remarks : ' In Mr. Bateman's 

 magnificent work we are told how the 

 long-spiked small purple-flowered C. Eger- 

 tonianum is only the short-spiked large 

 green-flowered C. ventricosum; how the 

 same plant at one time bears one sort of 

 flowers, and at another time another sort ; 

 and we have ourselves shown how the 

 same plant, nay the same spike, is some- 

 times both the one, the other, and neither. 

 C. Egertonianum is then a ' sport,' as gar- 

 deners say, of C. ventricosum. But what, 

 again, is C. ventricosum ? Who knows that 

 it is not another 'sport' of G. Loddigesii, 

 which has indeed been caught in the very 

 act of showing a false countenance, some- 

 thing wonderfully suspicious, all things
