and Japan, and being hardy enough to sus- 

 tain our climate without injury, is now 

 very generally planted in collections of 

 Conifers. It is not, however, suited to 

 heavy soil. 



CRYPTONEMATA. Small cellular 



threads produced by cryptostomata. 



CRYPTOXEMIACE-E. One of the largest 

 natural orders amongst the rose-spored 

 Algce, belonging to the section Gongylos- 

 permece, in which the inarticulate cartila- 

 ginous frond consists of a number of 

 jointed threads compacted by gelatine. In 

 the membranous species it is sometimes 

 formed of many-sided cells, decreasing in 

 size towards the surface. The capsules are 

 immersed and are sometimes compound, 

 and the spores are congregated without 

 order. These arise either from several 

 congregated fertile cells, which at length 

 enlarge their endochrome, giving rise to a 

 multitude of spores, or from a single cell, 

 according as they are compound or simple ; 

 in the former case all trace of the original 

 structure is frequently lost when the fruit 

 is perfected. The genera and species 

 are numerous, and occur in all climates. 

 Chondrns crispus with several species of 

 I Iridcea and Gigartina belonging to this 

 i order, abound in gelatine, and in conse- 

 I quence are useful for many domestic pur- 

 ! poses. [M. J. B.] 



CRTPTOPHYTES. A synonym of cryp- 

 togams. [M. J. B.] 



CRTPTOPUS electa (Beclardia of Rich.) 

 is a handsome epiphytal orchid from the 

 Isle of Bourbon. It has the habit of Epi- 

 dendrum elongatum, the double gland and 



j caudicle of an Angrcecum, and flowers with 

 deeply-lobed petals and lip ; their colour is 



| white dotted with purple. 



CRTPTOS. In Greek compounds=con- 

 cealed; thus Cryptogams are plants with 

 concealed sexes. 



CRYPTOSANCS. Leochilus. 



CRYPTOSEMA. A name sometimes 

 given to a "West Australian bush of the 

 pea family, also called Jaxsoxia : which 

 see. [A. A. BJ 



CRYPTOSORTTS. A very appropriate 

 name proposed for a few species of small- 

 growing Ferns, having sunken punctiform 

 nonindusiate sori, but which are not gene- 

 rally considered sufficiently distinct from 

 Polypodium. [T. MJ 



CRYPTOSTEGIA. A genus of twining 

 shrubs, belonging to the natural order 

 Asclepiadacew, and containing a single 

 species from India and another from Mada- 

 gascar. They have opposite leaves, and 

 large reddish-white flowers in terminal 

 cymes. The calyx consists of five lanceo- 

 late sepals; in the tube of the corolla 

 there are five linear bipartite scales ; the 

 stamens are included, and have very short 

 i filaments inserted at the base of the tube, 

 I J and the oval pollen masses are solitary 

 j and attached to the five glandular points 



on the globose stigma. The large three- 

 sided follicles are widely divaricate, with 

 an incurved apex and comose seeds. 



The plants of this genus abound in milky 

 juice, which when exposed for a short 

 time to the sun is converted into pure 

 caoutchouc. [w. CJ 



CRYPTOSTOMATA. Little circular nu- 

 clei found on the surface of some algals. 



CRYPTOSTYLIS. A small genus of 



brown-flowered terrestrial orchids inhabit- 

 ing New Holland, Java, and Ceylon. The 

 main character consists in its having a 

 great dorsal lip hollowed out at the base 

 to receive the column. - The abolished 

 genus Zosterostylis is one of the species. 



CRYPTOT^ENIA. A genus of Umbelli- 

 fercB. The Honewort, C. canadensis, is the 

 only species, and is one of a goodly number 

 of plants common to North America and 

 Japan. It is a smooth perennial erect 

 herb, one to two feet high, having ternate 

 stalked leaves with ovate coarsely-toothed 

 leaflets, and numerous umbels of small 

 white flowers, curiously disposed in an 

 almost panicled manner, which is very 

 unusual in the family. The fruit is linear- 

 oblong, contracted at both sides, each of 

 the carpels having five equal obtuse ribs, 

 with an oil tube (vitta) in each furrow, 

 and one under each rib. [A. A. B.] 



CRYPTOTHECA. A genus of Lythracece, 

 containing bog herbs or undershrubsfrom 

 Japan with angular stems, opposite shortly 

 stalked lanceolate or linear-lanceolate 

 leaves, and axillary many-flowered pe- 

 duncles. The calyx is funnel-shaped, four- 

 cleft; corolla of four small petals or ab- 

 sent ; stamens two, with roundish anthers; 

 style lateral ; capsule one-celled, irregu- 

 larly circumscissile, inclosed in the calyx 

 tube. [j. T. S.] 



CRYPTOTHECII. A small group of 

 mosses, represented by Spiridens. 



CRYSTAL WORTS. A name given by 

 Lindley to the Ricciacece. 



CTENOMERIA. A genus of slender 

 twiners of the spurgewort family, found in 

 South Africa. The slender cobwebby fila- 

 ments of the male flowers, together with the 

 pectinately-toothed calyx leaves of those of 

 the females, serve to distinguish it from 

 its allies. The wiry stems are furnished 

 with distant nettle-like heart-shaped leaves, 

 and the small green flowers are disposed 

 in racemes which arise from opposite the 

 leaves. [A. A. BJ 



CTENOPTERIS. A name originally pro- 

 posed as a sectional division of Polypodium 

 by Blume, a Dutch botanist, and subse- 

 quently adopted as a genus, with various 

 modifications by modern pteridologists. It 

 is, however, synonymous with the true or 

 typal species of Polypodium. [T. M.] 



CUBEBA. A genus of Piperacece, the 

 distinguishing features of which are, the 

 dioecious flowers partially covered by ses- 

 sile bracts and the fruits elevated on a
