GREVILLEA 



fid: fls. red, small and very many in dense cylindrical 

 racemes 4-8 in. long, silky outside, glabrous or nearly 

 so inside: fr. nearly 1 in. long, slightly compressed. 

 B.M. 7524. Pink and white varieties are mentioned, 

 glabrata, Meissn. (G. Manglesii, Hort.). Shrub, 

 glabrous, slender: Ivs. 1-1 ^ in. long, broadly cuneate, 

 shortly and acutely 3-lobed: fls. white, in axillary 

 racemes equaling the Ivs. or the upper racemes panicled, 

 the perianth glabrous, the tube much exceeding the 

 globular limb. Offered abroad as a bright green orna- 

 mental foliage plant of drooping habit.

GREWIA (Nehemiah Grew, of Coventry, 1628-1682, 

 author of a work on anatomy of plants). Tilidcese. 

 Two or three woody plants slightly cultivated in 

 southern Florida. 



A genus of about 70 species of trees and shrubs in 

 the warmer parts of the world, often having stellate 

 pubescence: Ivs. entire or serrate, 1-9-nerved: fls. 

 yellow or rarely purple, in axillary, few-fid, cymes or 

 terminal panicles; petals 5, with pits or glands inside 

 at the base; stamens indefinite; ovary 2-4-celled: 

 drupe 1-4-stoned. G. Caffra, Meissn., from Natal, 

 was intro. by Reasoner Bros, in 1891. A bushy plant 

 with young shoots and lys. glabrous and with purple 

 star-shaped fls. borne during most of the year. G. den- 

 ticulata, Wall., from India, was never described. Under 

 this name Reasoner cult, a plant "resembling a mul- 

 berry in growth, which bears enormous quantities of 

 acid drupes, about the size of cranberries; used for 

 pickling." G. oppositifolia, Roxbg., is a rough, much- 

 branched tree, with distichous, crenate-serrate Ivs. and 

 fls. in umbellate cymes, borne opposite the Ivs.: fls. 

 yellowish, the oblong petals half the length of the 

 sepals. The species are little known in Amer.

GREYIA (after Sir George Grey, once Governor of 

 Cape Colony). Often spelled Greya. Melianthacese. 

 A small tree from Natal, which bears large spikes of 

 pendulous, five-petaled, scarlet flowers, and is culti- 

 vated outdoors in southern California and abroad under 

 glass in many botanic gardens. 



Species probably 3, but only 1 appears to be in cult.; 

 in R.H. 1894:252 this plant is shown at its best, with 

 a spike 6 in. long and 2-3 in. wide, containing probably 

 over 100 fls., each %in. across. In France this tree 

 flowered from the end of autumn throughout the 

 winter. The long-exserted stamens with reddish pur- 

 ple anthers make a striking feature. The structure of 

 the fls. is so peculiar that Harvey referred the genus 

 doubtfully to the saxifrage family. In European green- 

 houses, greyia is a shrub requiring full sunlight, 

 thorough ripening of the wood and a season of rest 

 before flowering. In Natal it flowers in Aug. or Sept., 

 which is early spring there. Europeans recommend 

 a sandy loam. Prop, by seeds or by cuttings from half- 

 ripened wood. 



Sutherland!!, Hook. & Harv. Small tree, with thick, 

 naked branches and light-colored bark: Ivs. clustered 

 at the ends of the branches, 2-3 in. long, orbicular, 

 ovate or oblong, deeply cordate at base, toothed ; petiole 

 9-12 lines long: fls. bright crimson; disk cup-shaped, 



GRINDELIA 



1413 



with 10 marginal teeth, each crowned by a peltate 

 gland; stamens 10; ovary laterally 5-lobed, 5-celled; 

 ovules numerous, in 2 series in the inner angle of the 

 cells: fr. capsular, 5-valved; seeds albuminous. B.M. 

 6040. R.H. 1894:252. G.C. II. 19:625; III. 43:138. 

 J.H.III.30:101. N. TAYLOR.! 



GRIAS (name refers to the fr. being edible). Lecyth- 

 iddcese. Tall W. Indian trees, with branches short or 

 none and very large alternate simple Ivs., one of them 

 known for its edible fr.: fls. large, white or yellow, 

 lateral; calyx entire in bud, but becoming 2-4-lobed or 

 torn; petals spreading, 4 or 5; stamens many, in many 

 or several rows on the disk, the inner ones smaller, the 

 fleshy filaments conniving into a globular involute 

 body, the anthers small and the cells distinct: fr. fleshy, 

 ovoid. Species about 4. G. cauliflora, Linn., produces 

 the Anchovy pear: Ivs. 2-4 ft. long, lanceolate-acumin- 

 ate, entire, drooping, glossy, borne in palm-like tufts 

 or heads on the top of the st. or ends of branches.: 

 fls. on short branching peduncles from the old st. far 

 below the Ivs., fragrant, 2 in. across, yellow: fr. ovoid, 

 2-3 in. long, 8-grooved, brown, fleshy, with 1 seed, said 

 to be edible. W. Indies. B.M. 5622. L. H. B. 



GRIFFINIA (after William Griffin, who brought these 

 plants from Brazil) . Amaryllidacese. Brazilian bulbs, with 

 distinct foliage, and flowers, about 2J^ inches across, 

 which are more or less tinged with lilac or rose. 



Leaves usually petioled, and with a very broad 

 blade: perianth-tube none or very short, the 3 lower 

 segms. narrower than the upper; ovary 3-celled; 

 stigma capitate, rarely 3-fid; umbel 6-15-fld. Griffinia 

 is distinguished from many other genera by its 2 

 ovules, which are basal and collateral. Seven species. 

 Like many other genera of the amaryllis family, bulbs 

 of flowering size are too costly for general use. Very 

 doubtfully in cult, in Amer. 



A. Stigma capitate. 



hyacinthina, Herb. Bulb globose: Ivs. 6-9 in. long, 

 2-3 in. broad, rounded at the base to a channeled peti- 

 ole as long as the blade: scape 1-2 ft. long; pedicels 

 none or very short; stamens much shorter than the 

 segms. B.R. 163 (as Amaryllis hyacinthina; upper 

 segms. tinged blue, lower ones nearly white). J.H. 

 III. 31: 371; 55: 325. G.M. 47:45. Var. maxima, Gn. 

 50, p. 209, is probably the best garden form. Called 

 "blue amaryllis" in some catalogues. 



AA. Stigma distinctly S-cut. 



Blumenavia, Koch & Bouche". Bulb ovoid: Ivs. 4-5 

 in. long, cuneately narrowed to a petiole, shorter than 

 the blade: scape 6-8 in. long; pedicels %m. long; sta- 

 mens as long as the perianth. B.M. 5666 (veins rose- 

 colored). R.H. 1867:32. Gn. 50:208 (veined and 

 flushed with rose). N. TAYLOR.! 



GRINDELIA (Hieronymus Grindel, of Riga and 

 Dorpat; died 1836). Composite. Hardy plants sometimes 

 cultivated for their showy yellow flowers, which are 1 % 

 to 2 inches across and borne freely all summer. 



Herbs, sometimes shrubby, of coarse habit, mostly 

 natives of the U. S. west of the Mississippi: Ivs. sessile 

 or partly clasping and usually serrate and rigid: heads 

 terminating the branches, solitary or in cymes or 

 panicles; involucre bell-shaped or hemispheric, the 

 bracts many-ranked. The plants often have a sticky 

 balsam, especially the heads before and during flower- 

 ing, whence they are called "gum-plants" in Calif., 

 particularly G. robusta, which is the common one. The 

 two species first described below have roots that are 

 perennial and short-lived, but sometimes annual. 

 These plants are also glabrous, and have firm or rigid 

 Ivs. This genus contains 2 plants from which a fluid- 

 extract is obtained that is used externally as an anti- 

 dote for poisoning by "poison ivy." Species about 25.
