having the calyx in five deep divisions, 

 which are very narrowand acute ; and five 

 stamens attached to the lower part of the 

 tube of the corolla, their anthers perfect. 

 The species are Indian shrubs, erect and 

 smooth ; the leaves opposite, stalked and 

 of thin texture ; the flowers in terminal 

 and lateral bunches. [G. D.J 



HOLBGELLIA. A small genus of Lardi- 

 zdbalacece, consisting of scandent shrubs, 

 natives of India, and having digitate 

 leaves, and axillary corymbiform racemes 

 of purple or greenish flowers, which are 

 monoecious, with six petaloid sepals and 

 six minute petals. In the male flowers 

 there are six free fertile stamens, and in 

 the female six small sterile ones and 

 three ovaries, which become oblong in- 

 dehiscent berries. [T. M.J 



HOLCOSORUS. A peculiar Bornean 

 fern, referred by some botanists to Gram- 

 mitis and Polypodium, but by others 

 considered to form a distinct genus of 

 the Tcenitidece. The fronds are solid and 

 bluntly pentangular, with three grooves 

 on the upper and two on the lower surface, 

 the oval-oblong naked sori lying in the 

 latter. The venation is reduced to a sim- 

 ple costa, imbedded in the centre of the 

 narrow wiry fronds. H. pcntagonus is the 

 Grammitis bisulcata of Hooker. [T. M.J 



HOLCUS. A genus of grasses, mostly 

 European, belonging to the tribe Phalarece, 

 and distinguished by its somewhat open 

 panicle with numerous crowded two-flow- 

 ered spikelets. The upper flower is male, 

 and has a shortly-awned glume, and the 

 lower one is hermaphrodite, with the 

 glume usually awnless. The outer glumes 

 are boat-shaped, enclosing the flowers. 

 Two species are natives of Britain, but 

 they have soft woolly herbage, and are of 

 little value. [T. M.J 



HOLEWORT. Corydalis bulbosa. 



HOLIGARNA. A genus of lofty Indian 

 trees, belonging to the Anacardiacece, and 

 distinguished by the parts of the flower 

 being arranged in fives ; the petals oblong, 

 hairy, spreading, attached to the five- 

 toothed calyx ; the ovary united to the 

 tube of the calyx, and containing a single 

 ovule at its upper part ; and the fruit 

 fleshy, with a one-seeded stone. From the 

 stem of H. longifolia, a lofty tree, occasion- 

 ally cultivated in our stoves, the natives 

 of Malacca are said to extract an acrid 

 juice, which is used as a varnish. The 

 stone of the fruit likewise contains an 

 acrid resinous juice, while the investing 

 pulp contains a glutinous fluid made use 

 of by painters, and for fixing colours on 

 linen*. The fruit and the bark are used 

 medicinally, but require to be employed 

 with caution, as they are apt to give rise 

 to dangerous symptoms. [M.T. M.]

HOLOGRAPHIS. A genus of Acantha- 

 cece, containing a single Mexican species, 

 a branchingundershrub, with oblong-ovate 

 obtuse leaves, and axillary flowers in pairs. 

 The calyx is equally five-parted, and the 

 corolla ringent, with a very short tube. 

 It has four didynamous stamens. [W. C.J 



HOLOLACHNE soongarica is a plant 

 of the Beaumuria family, which grows in 

 saline places on the shores of lakes in 

 Soongaria and Mongholia. It is a few 

 inches high, much-branched, with white 

 wiry stems furnished with numerous 

 minute linear clustered fleshy leaves, bear- 

 ing inconspicuous white flowers in their 

 axils. The few (eight to ten) stamens, and 

 the absence of scales at the base of the pe- 

 tals, are the chief characters. [A. A. B.J 



HOLOSERICEOUS. Silky; so covered 

 with hairs that it feels soft to the touch, 

 although the naked eye may fail to detect 

 the presence of hairs. 



HOLOSTEMMA. A small genus of As- 

 clepiadacece, from tropical Asia, consisting 

 of twiners with largish flowers, deeply 

 coloured inside and arranged in shortly 

 pedunculate interpetiolar umbels or ra- , 

 cemes. The corolla is rotate with a short 

 tube, and the limb divided into five broadly 

 ovate lobes. [W. C.J 



HOLOSTEUM. A small genus of Caryo- 

 phyllacece, with the styles usually three and 

 the capsule valves twice as many. They 

 are small annuals found in Europe, North 

 Africa, and temperate Asia, wit'' simple 

 stems, smooth oblong leaves in pairs, some- 

 times united at the base, and terminal 

 umbels of small chickweed-like flowers. 

 H. umbellatum is found in a few of the 

 eastern counties of England, but is far 

 from common. [J. T. S.J

HOMALIACE.E. (Homaliads.) A natural I 

 order of monochlamydeous dicotyledons i 

 included in Lindley's cactal alliance of epi- 

 gynous Exogens. Trees or shrubs with | 

 alternate leaves ; perianth funnel-shaped, ; 

 with five to fifteen gland-bearing divisions I 

 and alternating petaloid scales, the latter I 

 considered by some as petals, and hence | 

 Lindley places the order between Loasacece j 

 and Cactacece; stamens inserted on the pe- 

 rianth, either singly or in bundles of three i 

 or six ; ovary adherent, one-celled; ovules
