Grias ; a genus of the class Polyandria, order Monogynia. 

 GENERIC CHARACTER. Calix: perianth one-leafed, cup- 

 shaped ; mouth four-cleft, finally lacerated. Corolla : petals 

 four, roundish, concave, coriaceous. Stamina: Filamenta 

 numerous, setaceous, longer than the corolla, inserted into 

 the receptacle; antherse roundish. Pistil: germen somewhat 

 depressed, immersed in the calix ; style none ; stigma thick- 

 ish, four-cornered, hollowed out crosswise. Pericarp : drupe 

 large, one-celled, acuminate at the base and tip. Seeds: 

 nucleus scored with eight furrows. ESSENTIAL CHARAC- 

 TER. Corolla: four-petalled. Calix: four-cleft. Stigma: 

 sessile, cross-shaped. Drupe: with an eight-furrowed nu- 

 cleus. The only known species is, 



1. Grias Cauliflora; Anchovy Pear. Branches at the top 

 simple, short, or none ; leaves on short petioles, pendulous, 

 two or three feet long, wedge-shaped at the base, oblong, 

 attenuated, entire, marked with nerves and veins, wrinkled, 

 smooth ; flowers from the stem, yellowish-white, fragrant, on 

 very short, scaly, many-flowered peduncles ; pedicels short, 

 crowded, one-flowered ; corollas about the size of a half- 

 crown. This tree frequently grows to the height of fifty feet, 

 and the uprightness of the growth, and the largeness of the 

 leaves, give it a very elegant appearance. The fruit is 

 pickled in the West Indies, and eaten in the same manner 

 with the East Indian Mango, which it exactly resembles in 

 taste ; it is about the size of an alligator's egg, and much 

 like it in shape, only a little more acute at one end, and of a 

 brown russet colour. Native of all the hottest parts of the 

 West Indies, and common in many parts of Jamaica, grow- 

 ing generally in low moist bottoms, or shallow waters. To 

 propagate it, put the stones into the ground soon after the 

 fruit is gathered, and keep the plants constantly in the bark- 

 bed in the stove. In the West Indies the seeds grow very 

 readily, wherever they meet with a sufficient quantity of 

 moisture, and propagate so thick, that the trees are always 

 found formed into thickets, or large clusters. 



Grielum; a genus of the class Decandria, order Pentagy- 

 nia. GENERIC CHARACTER. Calix: perianth one-leafed, 

 spreading, deeply five-cleft, flat at the base, sharp, equal, 

 permanent. Corolla : petals five, spreading, large, obovate, 

 sessile, tapering at the base ; nectaries oblong ; glands placed 

 round the germen, and united so as to form a crown. Sta- 

 mina: filamenta ten, filiform, somewhat rigid, equal, per- 

 manent, the length of the calix ; antherse ovate-oblong, 

 upright. Pistil: gennina five, distinct, awl-shaped, upright, 

 shorter than the stamina ; styles none ; stigmas capitate, 

 warty. Pericarp: capsules five, oblong, acuminate, hard, 

 formed from the calix, five or ten celled. Seed : solitary, 



oblong. Observe. It is not certain whether there be a dif- 

 ference of sex, or a withering of the pistil in some individuals. 

 ESSENTIAL CHARACTER. Calix : deeply five-cleft. Petals: 

 five. Filamenta : permanent. Capsules : five, with one seed 

 in each. The only known species is, 



1. Grielum Tenuifolium. Stem shrubby, diffuse and very 

 much branched, clothed, like the leaves, with a white cot- 

 tony down. The petals are blue, with livid yellow claws. 

 Capsule inferior, with the calix closely adhering, and serving 

 as a bark to it at bottom, flatfish at top, and surrounded 

 with a ring of hard bony tubercles, within which it js crowned 

 with the permanent filamenta and styles : it has ten cells, 

 but no valves : to each style there are two cells, but all of 

 them are placed in a ring, regularly round the axis of the 

 fruit, and deeply immersed in the substance of the calix. 

 There is no receptacle, but the seeds are fixed to the tip of 

 the cells, only one in each ; the form is elliptic, beaked at 

 top, plano-convex, or flatted lens-shaped, of a reddish chest- 

 nut colour. Native of the Cape. 



Grimmia ; a genus of the class Cryptogamia, order Musci. 

 ESSENTIAL CHARACTER. Capsule: ovate. Fringe : simple, 

 of sixteen teeth, broadest at their base. Flowers: terminal. 

 Veil: cylindrical. Twenty-nine species have been described ; 

 some of them belonging to the Linnean species of Bryum. 



Grislea ; a genus of the class Octandria, order Monogynia. 

 GENERIC CHARACTER. Calix: perianth, one-leafed, 

 awl-shaped, inclined to bell-shape, upright, four-toothed, 

 coloured, permanent. Corolla: petals four, ovate, from the 

 incisures of the calix extremely minute. Stamina: filamenta 

 eight, awl-shaped, upright, long, ascending ; antherse sim- 

 ple, upright, roundish. Pistil: germen superior, globular, 

 pedicelled ; style filiform, the length of the stamina ; stigma 

 simple. Pericarp: capsule globular, shorter than the calix, 

 one-celled. Seeds: very many, roundish, very small; re- 

 ceptacle large. Observe : Sometimes one third part is added 

 to the parts of the flower. ESSENTIAL CHARACTER. Calix : 

 four-cleft. Petals: four, from the incisures of the calix. 

 Filamenta: very long, ascending. Capsule: globular, superior, 

 one-celled, containing many seeds. The species are, 



1. Grislea Secunda. Leaves ovate, lanceolate, smooth, 

 on petioles ; raceme terminating ; flowers all facing one way. 

 This is a tree, with round scattered branches. Calices of a 

 dark brownish crimson, bell-shaped, slightly angular; petals, 

 stamina, and style, of an elegant scarlet. Native of South 

 America. 



2. Grislea Tomentosa. Leaves half-lanceolate, with a cor- 

 date base, whitish beneath, sessile ; racemes axillary, short. 

 Stem, and principal branches, erect, smaller, ascending; bark 

 rust-coloured; calix red, six-toothed, equal, permanent; 

 petals six, small, lanceolate. This is a beautiful flowering 

 shrub, a native of the hills and valleys through the northern 

 provinces of the Carnatic in the East Indies. The bright red 

 calix, retaining its colour till the seeds be ripe, gives this 

 plant a very showy appearance. Linneus says it is also a 

 native of the West Indies.

 nent ; divisions semi-lanceolate, upright. Corolla : petals 

 five, extremely minute, roundish, from the clefts of the calix.

 form, longer than the stamina; stigma capitate, undivided. 

 Pericarp: berry dry, roundish, coloured, one-celled. Seed:
