KOBRE'SIA, a genus of Plants belonging to the natural order 

 Cyperacece. It has the spikes aggregate ; the lower flower pistiliferous. 

 the perigone of one scale inclosing the germen and covered by the 

 glume. The upper flower staminiferous without any perianth. There 

 is but one species of this genus, K. caricina, which has an erect stem 

 from 6 to 12 inches in height, slender leaves shorter than the stem, 

 from 4 to 5 spikes aggregated at the summit of the stem, and from 6 

 to 8 flowers. There is often an abortive stamen at the base of the 

 nut. This plant is found throughout Europe and in Great Britain, on 

 moors in Yorkshire, Durham, and Perthshire. (Babington, Manual 

 of Britith. Botany.) 



KOBUS. [ANTILOPE.E.] 



KOELE'RIA, a genus of Plants belonging to the natural order 

 Graminai:toe. It has unequal glumes, the upper one with 2 or 3 ribs, 

 shorter than the spikelet, which is compressed. The outer palea is 

 nerved, keeled, and acuminate ; the seed loose, and the styles terminal. 

 There is but one British species of this genus : 



K. cristate has a compact panicle, spiked, oval, and interrupted 

 below, the outer palea 8-ribbed and acute ; the leaves narrow, rough 

 at the edges, and ciliated. In dry places the leaves are much shorter 

 than the stem ; in damper places elongated, and often nearly as long 

 as the stem.

KOLLYRITE, a Mineral consisting of a hydrous silicate of alumina, 

 which occurs massive. Colour white. Fracture earthy. Nearly 

 opaque. Lustre somewhat vitreous. Hardness 3'25. Specific gravity 

 2-06 to 2'11. It is found at Schemnitz in Hungary, and in a lead- 

 mine on the bank of the river Oo, in the Pyrenees. The following 

 analysis is by Berthier :

KONIGA, a genus of Plants belonging to the natural order Cruci- 

 ferie. It has an oval compressed pouch, from 1 to 2 seeds in each 

 cell, simple filaments, and 8 hypogynous glands. But one British 

 species of this genus has been discovered, K. maritima, which is a 

 procumbent plant, with bipartite hairs, linear-lanceolate acute leaves, 

 oval pointed glabrous pods. It is the Lolularia of Koch, and the 

 (/tyce of Lindley. The flowers are white and sweet-scented. (Babington, 

 Manual of British. Botany.") 



KONIGITE, a Mineral consisting of sulphate of copper which is 

 insoluble. Krimviyite is one of the same species. 



KOODO. [ASTILOPEA] 



KRAMERIA, a genus of Plants belonging to the natural order 

 PtAijfjalac&z. It has 4 or 5 sepals, irregular, coloured, spreading, 

 deciduous ; petals 5 or 4, irregular, smaller than the calyx, the three 

 inner unguiculate; stamens 1, 3, or 4, hypogynous, unequal; ovary 



1 -celled, or incompletely 2-celled ; style terminal ; stigma simple ; 

 ovules in pairs, suspended. Fruit between hairy and leathery, globose, 

 covered with hooked prickles by abortion, 1-seeded, indehiscent. 

 The species are spreading many-stemmed undershrubs. The leaves 

 alternate, simple, entire, or 3-foliate, spreading; racemes simple, 

 spiked. 



}. triandra is found on dry gravelly and sandy hills in Peru, flower- 

 ing all the year round. It is known by the name of Ratanhy Root. 

 It is a suffruticose plant, with a horizontal very long and branched 

 root, with a thick bark, reddish-brown outside, red inside. It has a 

 procumbent stem, much branched and taper ; the branches are from 



2 to 3 feet long, when young, silky ; leaves alternate, sessile, oblong 

 and obovate, acuminate, entire, hoary on each side ; flowers solitary, 

 axillary, and stalked ; calyx silky externally, smooth and shining inside, 

 of the colour of lac. The two upper petals are separate, spathulate, the 



two lateral roundish and concave ; the drupe is dry and hairy, barred, 

 with dull red hooks. The extract of the plant is styptic and tonic, 

 and operates powerfully upon tumours, resolving and restoring tone 

 to those parts. When administered internally the extract of Ratanhy 

 is apt to be rejected by the stomach till three or four doses have 

 been taken. It is best to take it in the, form of pills. It is commonly 

 used in Peru as tooth-powder.

KUPFERSCHAUM, a Mineral containing arsenate of copper, which 

 occurs crystallised. Primary form a right rhombic prism. Occurs 

 in rhomboidal plates, which present perfect cleavage parallel to the 

 faces of the rhomb ; generally in small aggregated and diverging 

 fibrous groups of a pale apple-green or verdigris-green colour. Streak 

 paler. Hardness I'O to 1'5. Lustre pearly on the faces of the rhomb. 

 Translucent. Flexible in thin lamina:. Specific gravity 3'0 to 3'2. 

 It is found at Matlock in Derbyshire, in the a Bannat, at Lebether in 

 Hungary, in Siberia, the Tyrol, and at Saalfeld in Thuringia. Its

KYANITE (Cyanite, Diathene, Sappare). This Mineral occui-s 

 crystallised and massive. Its primary form is a doubly oblique prism. 

 The cleavage is parallel to the faces of the primary form. Frac- 

 ture uneven. Hardness of the sharp portions sufficient to scratch 

 glass. Colour white, yellow, and various shades of blue and green. 

 Streak white. Lustre vitreous, pearly. Transparent; translucent. 

 Specific gravity 3'6. 



By the blow-pipe it is infusible, and merely becomes white even in 

 a very sirong fire ; with borax it readily dissolves into a colourless 

 transparent glass. The following are analyses by Laugier and 

 Arfwedson :

T A'BEC (Cuvier), a genus of 1'ishes belonging to the family 

 C'yprinida. The species of this genus resemble the true Carps in 

 having the dorsal fin long, but they do not possess the strong spine of 

 the anal and dorsal fins. The lips are very thick and fleshy, and 

 more or less crenulated. There are no cirri. An illustration of this 

 genus will be found in the Cyjiriniu Niloticut of Geoffrey St. Hilaire. 

 (' Poiasons du Nil,' pi. xi. f. 2.) The Cyprinus fimbriatut of Bloch, 

 ' Hchu.,' p. 441, sp. 24, and the Catoitomut ci/i>rinus of I.tKueur, also 



belong to the genus Lateo, which has no representative in tho 

 European seas.
