! adherins to the nuts as far as their middle, 

 : and the peduncles thickened. [J. T. S.] 

 i HETEROCEPHALOUS. Bearing. in the 

 I same individual, heads of entirely male 

 flowers, aud others entirely female. 



HETEROCHiEXIA. A genus of hell- 

 worts, having the tube of the calyx ob- | 

 conical, deeply five-cleft, with the lobes i 

 ciliated ; seed-vessel three-celled, opening j 

 first by three valves at the summit, subse- j 

 quentfy by rupture of other parts. The , 

 genus was founded by De Candolle, to in- j 

 elude the Mascaren plant formerly called i 

 Wahlenbergia ensifolia. [G. D.] ; 



HETEROCODON. An annual from the i 

 Oregon territory in North America, dis- I 

 tinsuished as a genus of Camp aw dace ce. 

 by Nuttall, on account of the lower flowers 

 having no corolla; but it is probably only 

 a form or variety of Specularia perfoliata. 



HETERODOX. A genus of bruniads, 

 distinguished by the calyx having ten 

 teeth, five of which are short and blunt, 

 and five elongated. The only species is a 

 shrub, a native of the Cape, having semi- 

 cylindrical leaves, which are hairy, ending 

 in "awn-like points. [G. DJ 



HETEROGAMOUS. When in a capitu- 

 lu;n the florets of the ray are eitherneuter 

 or female, and those of the disk male. 



HETEROIDEOUS. Diversified in form. 



HETEROL.EXA. A subdivision of Pi- 

 melea in which the capitula are terminal, 

 and the involucre formed of four rarely 

 five to eight leaves, and these leaves are 

 j unlike the foliage of the branches, differ- 

 ing in magnitude or in form and texture, 

 often coloured. They are shrubby plants 

 of New Holland and Tasmania, with oppo- 

 site leaves. There are thirty-eight species 

 of Pimelea in this subdivision. [J. H.3B.] 



HETEROLEPIS. A small genus of Com- 

 posites, nearly related to Gazania, and found 

 in South Africa. The species differ from 

 this and their other allies, in having the 

 hairs of the pappus (which are of unequal 

 length and ciliated) in two or three series. 

 All are branching bushes, with rosemary- 

 like leaves, and handsome flower-heads 

 with the florets all yellow. [A. A. B.] 



HETEROMORPHA. A genus of um- 

 bellifers, distinguished from its congeners 

 by its peculiar fruit, which is apparently 

 five-winged owing to the different aspect 

 of its two halves, the outer being provided 

 with two wing-like ridges, the inner with 

 three. The species are natives of the Cape 

 of Good Hope. [G. D.] 



HETERONEME.E. A name applied to 

 the higher cryptogams by Fries to express 

 the fact of the more.complicated germina- 

 tion than in the lower cryptogams. The 

 production of the pseudoeotyledons in 

 ferns appears to be what he had more 

 especially in view. It may, however, be ob- 

 jected that in Puccinia and some other 

 fungi there is a decided prothallus preced- 

 ing the formation of true fruit. [M. J. B.] 



HETERONEURON. Pceciloptens. 



HETEROPAPPUS. The name formerly 

 given to a few Composites of North China 

 and Japan, with flower-heads like Aster. 

 They are now known to belong to the 

 genus Calimeris : which see. [A. A. B.] 



HETEROPHRAGMA. A genus of Big- 

 noviacece, containing a single species from 

 India. It is a large tree with opposite or 

 ternate impari-pinnate leaves, and whitish 

 flowers in dense terminal downy panicles. 

 The calyx is campanulate and three-lobed ; 

 the corolla equally five-parted, with the 

 margins of the divisions waved ; there are 

 four fertile stamens ; the ovary is sur- 

 rounded by a purple disk, and surmounted 

 by a simple style and a two-cleft stigma ; 

 the capsule is long and pointed ; and the 

 seeds have a broad wing. [W. C] 



HETEROPOGON. A genus of grasses 

 belonging to the tribe Andropogoneee, now 

 included in Andropogon. They are mostly 

 natives of Mexico. [D. M.] 



HETEROPSIS. A genus of Brazilian 

 plants, of the family Aretcece, deriving its 

 name from the fact that the appearance of 

 the planC is different from that of most of 

 its congeners. The stem is woody and 

 branching, with lance-shaped leaves; the 

 spathe hooded, deciduous ; spadix blunt, 

 covered with male and female flowers, in- 

 termixed ; the anthers are two-celled and 

 gaping ; ovaries two-celled, with two ovules 

 in each cell. [M.T.M.] 



HETEROPTERIS. A genus of American 

 climbing shrubs, with yellow or bluish 

 flowers, belonging to the Malpighiacece-. 

 Several are cultivated as evergreen stove 

 climbing plants ; their flowers have a calyx 

 with eight glands ; stamens all fertile ; 

 styles three ; fruit with a wing thickened 

 on the lower margin. [M. T. M.] 



HETEROS. In Greek compounds = va- 

 riable, or various. 



HETEROSTEMMA. A small genus of 

 Asclepiadacea?, natives of India and the Mo- 

 luccas. They are glabrous twining shrubs, 

 with opposite membranaceous leaves, 

 and flowers in few-flowered interpetiola.r 

 umbels. The calyx consists of five ovate 

 sepals ; the corolla is rotate and five-parted, 

 with spreading lobes. The five-leaved sta- 

 minal crown is very variable, differing in 

 each species. The follicles are smooth 

 and divaricate, and contain about twenty 

 comose seeds. [W. C] 



HETEROTOMA. Thename of a Mexican 



herbaceous plant, constituting a genus of 

 Lobeliacece. It has a two-lipped calyx ; a 

 tubular corolla, the tube of which is irre- 

 gularly dilated at the base into a spur-like ' 

 form ; anthers cohering, the two lower j 

 ones hairy ; ovary with two compartments ; j 

 stigma two-lobed. The flowers are large, 

 purple, arranged in racemes. E. lobelioides 

 is the Bird-plant of Mexico. [M. T. M.] | 



HETEROTROPA. The name applied to ! 

 a genus of Aristolochiacece, represented by 

 a Japanese herb, with a coloured pitcher- |
