[glos 



with Dipsacaceo;, but the plants of this 

 order have an inferior ovary. ["W. C] 



GLOBULEA. Succulent plants, natives 

 of the Cape, with flat or sickle-shaped 

 leaves, arranged in a rosette. The flowers 

 are small, arranged in dense clusters, and 

 have five petals bent inwards, each of them 

 tipped with a little globule of waxy matter, 

 whence the name of the genus, which 

 differs little from Crassula, save in the 

 direction of the petals. Several kinds are 

 in cultivation. [M.'T. M.] 



GLOBULINE, Elementary cells ; starch 

 grains. 



GLOBULUS. A kind of perithecium oc- 

 curring among fungals; the antheridium 

 of Cliara; also, a round deciduous shield, 

 found in such lichens as Isidium, formed 

 of the thallus, and leaving a hole where it 

 falls off. 



GLOCHIDION. A genus of the spurse- 

 wort family, comprising upwards of fifty 

 species of shrubs or small trees, for the 

 most part found in India, a few extending 

 eastward to Japan ; others occurring in 

 tropical Australia and the adjacent islands, 

 and three being natives of West Africa. 

 From Phyllanthus, to which they are closely 

 allied, they differ in the flowers being de- 

 stitute of a glandular disk, and generally in 

 the more numerous cells of the ovary. 

 Their alternate leaves are often arranged 

 in a distichous manner ; the blades of 

 some of them have a metallic lustre, while 



; others are clothed with soft short down. 



i Their inconspicuous yellow or green flowers 



, are male and female on the same plant, dis- 

 posed in axillary clusters, the males usually 

 occupying the circumference and the fe- 

 males the centre, both having a five or 

 six-parted calyx. The fruits are globular 



| or depressed capsules, sometimes covered 

 with a thin and fleshy red coat, but more 

 often quite dry ; when ripe they split into 

 three to ten portions. The bark of G. nitida 

 is said by Roxburgh to be astringent. 

 Bradle la and Gynoon are now referred to 

 this genus. [A.A.B.] 



GLOCHIS (adj. GLOCHIDATE). Hooked 

 back at the point, like a fish-hook. 



GLOIOCARP. The quadruple spore or 

 tetrachocarp of some algals. 



GLOMERATE. Collected into close heads 

 or parcels. 

 GLOMERULI. The same as Soredia. 



GLOMERULUS. A cluster of capitules 

 enclosed in a common involucre, as in 

 Echinops. 



GLORIOSA. The name of a group of 

 remarkably handsome hothouse herba- 

 ceous-stemmed climbers, more correctly 

 called Methonica : which see. [T. MJ 



GLORY-TREE. Clerodendron. 



GLOSSAPSI3 tentaculata is a tuberous- 

 rooted orchid, peculiar to the island of 

 Hong-kong and the adjacent mainland. Ac- 

 cording to Mr. Bentham, it has the habit 



and characters of the small-flowered Ha- 

 benarias, except that the terminal glands 

 of the caudicles of the pollen-masses are 

 received into distinct cells of the stigma. 

 The root is an ovoid tuber ; the stem, in- 

 cluding the slender erect spike of small 

 green flowers, eight to twelve inches high ; 

 the leaves three to four, oblong or lance- 

 shaped, and one to three inches in length ; 

 the lip is deeply three-lobed, the lobes long 

 and thread-like, somewhat resembling the 

 antenna? of an insect. [A. A. B.] 



GLOSSOCOMIA. A genus of bellworts 

 distinguished by having the calyx five- 

 lobed, reflexed; the corolla bell-shaped, 

 flve-lobed ; the stigmas three, ovate ; and 

 the fruit three-celled. G ovata is a hardy 

 downy perennial, a native of Northern 

 India, with ovate heart-shaped leaves and 

 showy bell-like flowers. [G. D.] 



GLOSSODIA. A small genus of Austra- 

 lian orchids, belonging to the tribe Are- 

 thusece, and most nearly related to Cala- 

 denia, of which, according to Dr. Hooker, 

 they may be considered a mere section, 

 with no glands on the disk of the lip, and 

 a solitary bifid long appendage at the base 

 of that organ, somewhat resembling a ser- 

 pent's tongue, whence the generic name. 

 They have tuberous roots ; a solitary lance- 

 shaped or oblong leaf, about three inches 

 long; and a slender, erect, nearly naked 

 stem, six inches to a foot high, bearing at 

 its apex from one to three extremely pretty 

 blue flowers, sometimes beautifully speck- 

 led with white, and about an inch in 

 diameter. The flowers are nearly regular, 

 the lip undivided, the column winged, and 

 the anthers terminal, with four powdery 

 compressed pollen-masses. [A. A. B.] 



GLOSSOLOGY. That part of Botany 

 which teaches the meaning of technical 

 terms. 



GLOSSOXEMA. A genus of Asclepia- 

 dacece, containing three species natives of 

 Arabia and North-Eastern Africa. They 

 are hoary perennial branching herbs, with 

 opposite linear leaves, and small flowers 

 on short interpetiolar peduncles. The 

 calyx is five-parted; the corolla campanu- 

 Iate and five-cleft, with a tubercle on the in- 

 ner surface of each lobe towards the apex ; 

 and the staminal crown is made up of five 

 lobes alternating with those of the corolla, 

 and having adilated emarginate apex, with 

 a contorted filament rising from the in- 

 dentation. The stigma is slightly two- 

 lobed ; the follicles smooth, or covered 

 with spines ; and the seeds comose. [W. O] 



GLOSSOPETALUM. A small Mexican 

 bush referred to the Celastracece, from the 

 other genera in which, it is easily recog- 

 nised by having ten stamens instead of 

 five, and a simple instead of a compound 

 pistil. G. spinescens is much branched, 

 two to four feet high, having stiff rounded 

 twigs, which end in spiny points, and are 

 furnished with littie alternate entire 

 leaves, those en the flowering twigs being 

 reduced to scale-like processes. The small
