GREEXHEART TREE. Nectandra Bo- 

 di(Bi. 



GREEN-MAN. Aceras anthropopliora. 



GREENS. The familiar domestic name 

 for open-hearted Cabbages, Kale, and other 

 leafy esculents ; also applied to Lemna. 



GREENWEED, or GREENWOOD, Ge- 

 nista tinctoria and pilosa. 



GREENWITHE. Vanilla claviculata. 



GREGGIA. A genus of Cruciferce from 

 New Mexico, discovered by Dr. Gregg, who 

 died in California through over-exertion in 



j scientific pursuits. This plant, called G. 



' camporum from its growing on the Campos 

 or plains, has the habit of a wallflower, and 

 all its parts clothed with hoary pubescence. 

 The stems are furnished with alternate 

 spathulate sinuate leaves, and the pink or 

 white flowers, somewhat J ike those of the 

 Bronipton stock but smaller, are disposed 

 in loose terminal racemes. The narrowed 

 pods isiliques) are about an inch long and 

 flattened laterally, so that the valves are 

 boat-shaped. The genus differs from others 

 of the Lepidium group, by its long pods, 

 and from its nearest allies in having in- 

 cumbent cotyledons. [A. A. B.] 



GREGRE TREE. Erythrophleum guine- 

 ense. 



GREGORIA. A genus of primworts, 

 having a five-cleft bell-shaped calyx ; a sal- 

 ver-shaped corolla, its tube dilated at the 

 upper end, with a border of five spreading 

 lobes , and five ovules, two only of which 

 reach maturity. The only species is a small 

 herb formerly known as Aretia Vitaliana, a 

 native of the Pyrenees. [G. D.] 



GRlSMIL. (Fr.) Lithospermum officinale. 



GREMILLET. (Fr.) Myosotis. 



GRENADIER. (Fr.) Tunica Granatum. 



GRENADILLE. (Fr.) Passiflora. 



GREXADIN. (Fr.) Bianthus Caryophyllus. 



GRENIERA. A genus of Caryophyllacece 

 which it has been proposed to separate 

 from Alsine on account of the seeds being 

 much compressed, with a transparent wing 

 round the back, and a thin layer of albumen 

 above the peripherical embryo. G. Dou- 



■ glasii and tenella are slender herbs from 

 California and Arkansas, with the habit of 



j Alsine verna and tenuifolia. [J. T. S.] 



GRENOUILLETTE. (Fr.) Ranunculus 

 acris, and others. 



! GREVILLEA. A genus of Proteacea?, 

 ! distinguished by having apetalous flowers ; 



■ a calyx which is either four-cleft or has 

 , four linear sepals broadish at the end ; four 

 ; ovate sessile anthers, one of which is at- 

 j tached to the concave apex of each sepal ; 

 ' and an elongated curved style, with the 

 | stigma either lateral or oblique, plane or 

 ! concave. The seed-vessel, called a follicle, 

 , is woody or leathery, containing one or two 

 I occasionally winged oval seeds. This is 

 i the most extensive and also the handsom- 



est genus of the order. It contains every 

 variety of form, from lofty trees a hun- 

 dred feet in height, with a girth of eight 

 feet, as in G. robusta, the Silk Oak of the 

 colonists, to humble procumbent shrubs, 

 as in G. lancifolia. The foliage is equally 

 varied : in G. juniperina, ericifolia, &c, it 

 is needle-shaped ; in G. glabella and junci- 

 folia, it is filiform ; in G. obliqua, poly- 

 stachya, and Leucadendron, it is linear, 

 twelve to eighteen inches in length ; in G. 

 asplenifolia and mimosoides, it is linear and 

 serrated ; in G. laurifolia it is ovate and 

 entire; in G. angulala and agrifolia it is 

 rounded at the apex, wedge-shaped and 

 serrated ; in G. ilicifolia, acanthifoliq, and 

 C'unninahamii, it is deeply cut, with sharp 

 prickly teeth ; in G. cinerea and buxi/vlta, 



Grevillea acanthifolia. 



box-leaved ; in G. anethifolia and triternata, 

 triternate ; in G. Gaudichaudii, Aqnifolium, 

 Sturtii, &c, pinnatifid ; in G. Banksii, Ca- 

 leyi, robusta, &c, pinnate or bipinnatifid. 

 The inflorescence is in spikes generally of 

 a deep rich red, occasionally yellow as in G. 

 sulphured, Banksii, and Chrysodendron. In 

 the latter species the flower-spikes exceed 

 one foot in length, and are extremely beau- 

 tiful. In G. Bryandri, asplenifolia, Caleyi, 

 and robusta, the flowers are also in long 

 spikes, of a deep red colour. The seed-vessels 

 in the following species are of a hard 

 woody substance, nearly spherical, from an 

 inch to two inches in diameter, viz. G. re- 

 fracta, mimosoides, and Leucadendron, and 

 especially G. gibbosa; these are all either 

 tropical or subtropical plants. The genus 

 is spread over every portion of Australia, 

 and two species, G. australis and G. Stuartii, 

 are found in Tasmania. [R. H.J 



GREWIA. An extensive genus of Tilia- 

 ceaz, consisting of shrubs or small trees, 

 with simple usually serrated leaves, natives 

 of the tropical and subtropical regions of 

 the Asiatic and African continents, and 

 also of the islands of the Malayan Archi- 

 pelago, the Fijis, &c, but not found on the
