a large number of the inhabitants of Pani, 

 •with whom Assai is a great favourite. 



E. montana, a West Indian species, is 

 cultivated in the hothouses of this country. 

 It attains a height of about twenty feet, 

 and has the base of its stern much swollen 

 or bulged out. The central portion of the 

 upper part of the stem, including the leaf- 

 bud, of this and the other species is eaten 

 either when cooked as a vegetable or pick- 

 led : but the tree must be destroyed in 

 order to obtain it. [A. S.] 



EUTHALES. A goodeniaceous genus, 

 native of the south-west coast of Austra- 

 lia. It bears a tubular unequally five-cleft 

 inferior calyx, a corolla cleft on one side 

 at the apex with a bilabiate limb, free 

 anthers, an undivided style, with theindu- 

 sium of the stigma bilabiate, and a four- 

 valved capsule. They are stemless herbs 

 with long-stalked nearly entire leaves, 

 and yellow flowers. [R. H.] 



EETHEMIS. A genus placed by some 

 authors in Sauvagesiacece, and by others in 

 Ochnacece ; differing from any in the former 

 in its berried fruit, and from any in the 

 latter in the fruit being composed of five 

 united carpels, instead of numerous free 

 carpels seated on a rounded and thickened 

 receptacle. It is composed of a few beauti- 

 ful little shrubs of the Malayan Archipelago, 

 having smooth rounded stems furnished 

 with alternate, elliptical or lance-shaped 

 leaves beautifully and minutely serrulate 

 at the margins, and the glossy blades ex- 

 quisitely marked with a great abundance 

 of parallel nerves running at right angles 

 to the midrib, the spaces between them 

 forming a beautiful network of veinlets. 

 The flowers are white or tinged with pur- 

 ple, and disposed in axillary or terminal 

 compound racemes. [A. A. B.] 



EUTHYSTACHYS. A genus of Stilbacece, 

 entirely confined toS. Africa, and differing 

 from its nearest ally, Campylostachys, in its 

 straight, not curved, flower-spikes, whence 

 the name of the genus, and in the little 

 funnel-shaped corollas, which have a five- 

 lobed instead of a four-lobed border. The 

 only known species, E. abbreviata, is a 

 smooth shrub, with heath-like four-ranked 

 leaves thickly set on the stems, which ter- 

 minate in a bracted spike of flowers. From 

 the other genera this differs in having a 

 calyx two of whose narrow segments are 

 free, and three are united by their margins 

 nearly to the summit. [A. A. B.] 



ETTTOCA. Annual herbs belonging to 

 the Hydrophyllacece, of an erect habit, with 

 rough leaves, and clusters of showy flowers. 

 They are natives of North America, especi- 

 ally California, and are often grown in 

 European gardens. The species mostly 

 cultivated are E. Menziesii or multiflora, 

 about eighteen inches high, with downy 

 narrow leaves, either entire or lobed, and 

 blue flowers. E. viscida is much branched, 

 with heart-shaped deeply-cut toothed 

 clammy leaves, and elongated racemes of 

 blue flowers with a rose-coloured tube. 



All the species are elegant and hardy. 

 French, Entoque. [C. A. J.] 



ETJTRIANA. A genus of grasses be- 

 longing to the tribe Cldoridece. The in- 

 florescence is for the most part in short 

 racemose spikes ; spikelets one-sided, al- 

 ternately sessile, two to three-flowered ; 

 glumes two, keeled, the exterior larger ; 

 pales two, of thickish texture, the inferior 

 one three-cleft, the superior two-keeled. 

 The score of known species are nearly all 

 natives of South America. [D. M.] 



EUTROPIS. An imperfectly described 

 genus of Asclepiadacecc, containing a sin- 

 gle species, abundant in the Punjab, and 

 forming a low twining fleshy lance-leaved 

 undershrub. Its position is between Calo- 

 tropis and Paratropis, having the angular 

 and saccate sinuose corolla, membrane- 

 lipped anthers and corona of the former ; 

 and the coronal leaflets cleft, and the 

 pollen masses oval and ventricose, as in 

 the latter. [W. C] 



EUXENIA. A genus of opposite-leaved 

 Chilian shrubs belonging to the compo- 

 site family, and distinguished amongst its 

 allies by each yellow flower-head being 

 entirely composed of unisexual florets, 

 all of which are tubular and five-toothed. 

 The leaves, somewhat rough to the touch, 

 are broadly oval or lance-shaped; and the 

 globose yellow flower-heads usually grow 

 two or three together, and are stalked at 

 the ends of the twigs, and about (half an 

 inch across ; the achenes are four-sided, 

 without pappus. There are but two species. 

 E. grata, with broadly oval leaves, is called 

 by the Chilians Palo Negro ; the other, E. 

 Mat i qui, with lance-shaped leaves, is called 

 Matiqui. In both the leaves have a plea- 

 sant aromatic scent. [A. A. B.] 



EVANESCENTI-VENOSE. When lateral 

 veins disappear within the margin. 



EVAX. A genus of Composites, found 

 in the Mediterranean region and in Cali- 

 fornia, and composed of a few minute 

 tufted annual herbs, having all their parts 

 clothed with white wool like many of the 

 cudweeds. In some species, as in E. erio- 

 sphcera, the whole plant does not exceed a 

 quarter of an inch in diameter, and looks 

 like a little ball of wool, whence the spe- 

 cific name. None of them exceed four 

 inches in height, and if branched the 

 branches are not more than two inches 

 long, and terminate in a sessile flower- 

 head surrounded by a rosette of oblong 

 woolly leaves. The genus is chiefly dis- 

 tinguished among its allies by the elonga- 

 ted cone-shaped receptacle on which the 

 florets are seated, and by the achenes 

 being destitute of pappus. [A. A. B.] 



EVELYN A. A numerous genus of South 

 American epiphytal orchids, found grow- 

 ing on stems and trunks of trees, and 

 readily known by their habit. They have 

 erect wiry stems, one to three feet high, 

 furnished with lance-shaped strongly rib- 

 bed leaves, and terminating in a few- 

 flowered spike, the flowers enveloped by
