the parts are crumpled up irregularly, as 

 the petals of the poppy, or the skin of 

 some seeds. 



COR SEMINIS. An old name for the 

 embryo. 



CORTEX. The bark. Also the peridium 

 of certain fungals. 



CORTICAL INTEGUMENT. The hark, 

 or false bark of endogens. 



CORTICAL STRATUM. The superficial 

 layer of tissue in the thallus of a lichen. 



CORTICATE. Harder externally than 

 internally : having a rind, as the orange. 



CORTINA. The filamentous ring of 

 certain agarics. 



CORTINARITJS. A large genus of Fungi, 

 separated from Agaricus more from habit 

 than from any striking characters. The 

 spider-like veil, and bright red-brown 

 spores resembling in tint that of peroxide 

 of iron, are the most easily recognised cha- 

 racters. In the woods of Sweden they 

 form by far the larger part of the mass of 

 Fungi, and in our own country are some- 

 times very abundant. There is scarcely a 

 single species which is received into Euro- 

 pean cookery, but in Bhotan one or two 

 are eaten. Many of the species are ex- 

 tremely beautiful in point of colour, es- 

 pecially when young. They alter wonder- 

 fully in this respect in dry weather or as 

 they pass maturity. [31. J. B.] 



CORTINATE, CORTINARIOUS. Having 

 a cobweb-like texture. 



CORTISIA. A genus referred to FJire- 

 tiacece, consisting of a much-branched shrub 

 from the Pampas of South America, hav- 

 ing alternate sessile wedge-shaped leaves 

 trifid at the apex, and small white tuber- 

 cles on both surfaces, from which tubercles 

 spring white hairs. Flowers solitary, ses- 

 sile, generally terminal, with a tubular 

 calyx having ten small teeth ; corolla 

 yellowish-white tubular, with a five-lobed 

 spreading limb; stamens five exserted; 

 style thread-like, cleft at the apex ; fruit, an 

 ovate drupe with two seeds. [J. T. S.] 



CORTUS A. A genus of Primnlacece, con- 

 taining a single species, a native of alpine | 

 and boreal districts in the Old World. It j 

 is a herb with the radical leaves on long 

 petioles, and with simple scapes bearing j 

 pedicellate flowers in umbels. The calyx | 

 is five-parted ; the corolla has a very short j 

 tube, and a carnpanulate limb : the five 

 included stamens are inserted at the base 

 of the limb with very short filaments and 

 obcordate anthers ; the capsule is five- 

 valved, and many-seeded, and dehisces 

 from the apex. [W. C] 



CORTUS ALES. A name given by Lind- 

 ley to a group of perigynous exogens, con- 

 taining among others the primrose and the 

 thrift families. 



CORTANTHES. Under this name, formed 

 in allusion to the resemblance of a part 

 of the flower to a helmet, is collected a set 



of epiphytal orchids inhabiting tropical 

 America, which are the strangest of all the 

 strange forms of that extraordinary order. 

 From one or two-leaved pseudobulbs hang 

 down few-flowered racemes of flowers vary- 

 ing in length from two to five inches long, 

 with the following singular structure. 

 For the sepals there are two large mem- 

 branous plates folding like a bat's wings, 

 with a smaller interposed. In front hangs 

 down a fleshy lip, bucket-like at the base, 

 and expanding into a great helmet-shaped 

 terminal lobe, whose weight keeps it al- 

 ways downwards, the cavity being turned 

 upwards. The column is a long twisted 

 recurved body with a vertical anther, con- 

 taining a pair of excavated pollen masses. 

 At the foot of the column are two fleshy 

 feet, from whose toe perpetually distils a 

 clear honey-like fluid, which drops into the 

 hollow of the helmet. The meaning of so 

 strange an apparatus is at present unex- 

 plained. Six species are known, of which 

 C. Fieldingi has the largest flowers, five 

 inches long and three wide when closed, 

 and C. distillatoria the smallest. 



CORTCIUM. A remarkable genus of or- 

 chids related to Ceratandra, and, like it, 

 turning black in drying ; the most marked 

 difference between the two consisting in the 

 petals of Corycium being saccate, and the 

 lateral sepals connate.so as to form a narrow 

 concave lower lip. Nine or ten species 

 have been described, all inhabiting the 

 Cape of Good Hope, and having close spikes 

 of purplish or greenish flowers. One of 

 them, Corycium orobanchoides, has been in 

 cultivation. 



CORTDALIS. A genus of Fumariacece, 

 containing succulent-stemmed herbs, na- 

 tives of the Northern Hemisphere. They 

 have ternate or twice ternate leaves, and 

 racemose flowers, which are very irregular. 

 Calyx of two lateral sepals ; corolla of four 

 petals, the upper one spurred or gibbous at 

 its base; stamens six, in two bundles of 

 three each, the filaments forming a ribbon 

 which is three-cleft at the end, the middle 

 lobe with a two-celled, the others each 

 with a one-celled anther ; a spur-like process 

 projects backwards from the upper ribbon, 

 and is received into the hollow space of the 

 upper petal. The capsule is a two-valved 

 one-celled pod with numerous seeds, which 

 have an appendage at the hilum. The 

 genus is divided into several sections :— 

 Capvites with no thickened tuberous root- 

 stock. Bulbocapnos with a roundish or 

 ovoid enlarged rootstock and alternate 

 leaves. Cryptoceras with a fusiform root- 

 stock and opposite leaves. [J. T. S.] 



CORYDALIS, CLIMBING. An American 

 name for Adlumia. 



CORYDANDRA. Fulophia. 



CORYLACE^E. (Cupulifera?, Castanece, 

 Quercinece, Mastviorts.) A natural order of 

 monochlamydeous dicotyledons, belong- 

 ing to Lindley's cmernal alliance. Trees or 

 shrubs bearing catkins, with simple, alter- 

 nate, stipulate, often feather-veined leaves,
