228 BROOM-KAPE FAMILY. 



e. MAKTYIHA, UNICORN-PLANT. (Named by Linnaus for Prof. 



MaHyn. ) Clammy-pubescent and 'heavy-scented rank herbs, with long- 



petioled rounded and obliquely heart-shaped wavy-margined leaves, and large 



flowers, in summer. ® 



M. proboscidea, Commok U. Wild S. "W., and cult, in gardens; 

 coarse, with nearly entire leaves, large corolla whitish with some purple and 

 yellow spots, and long-beaked fruit. ' 



M. frd:grans. Sweet-scented U. Cult, from Mexico ; less coarse and 

 clammy, with somewhat 3-Iobed or sinuate-toothed leaves, and showy violet- 

 purple vanilla-scented flowers. 



74. GESNERIACE.ffi, GESNERIA FAMILY. 



Tropical plants, with 2-lipped or somewhat irregular corollas, 

 didynamous stamens, a one-celled ovary with two parietal many- 

 seeded placentae, — therefore botanically like the next family ; but 

 with green herbage, and not parasitic, and the common cultivated 

 species have the tube of the calyx coherent at least with the base 

 of the ovary. Many, and som& very showy, plants of this order 

 are in choice conservatories ; the commonest are the following. 



Gloxinia speci6sa. An almost stemless herb, with ovate and crenately 

 toothed leaves and 1-flowered scape-like peduncles ; the deflexed corolla 2' long, 

 ventricose, between bell-shaped and funnel-foi-m, gibbous, with a short and 

 spreading somewhat uneq^ual 5-lobed border, violet with a deeper-colored throat, 

 in one variety white, y. 



Gesnferia zebrina. Stem tall, leafy ; leaves petioled, cordate, velvety, 

 pui-ple-mottled ; a terminal raceme of showy flowers nodding on erect pedicels ; 

 corolla tubular-ventricose, with a small 5-lobed and somewhat 2-lipped border, 

 glandular, scarlet, with the under side and inside yellow and dark-spotted. — 

 There are several other_.species. ^ 



Acbim^nes longinbra. Stem leafy ; flowers in the axils of oblong or 

 ovate hairy leaves, which they exceed ; tube of the obliquely salver-shaped 

 corolla over an inch long, narrow, the vei'y flat 5-lobed limb 2' or more broad, 

 violet-colored above, — also a white variety. Propagates by scaly bulblets from 

 the root. 11 



75. OROBANCHACE-ffil, BROOM-RAPE FAMILY. 



Low, root-parasitic perennials, destitute of green herbage, and 

 with yellowish or biowni.sh scales in place of leaves, the monopet- 

 alous corolla more or less 2-lipped or irregular, 4 didynamous 

 stamens, and one-celled ovary and pod with the 2 or 4 parietal pla- 

 centa covered with innumerable small seeds. Ours occur in woods, 

 and mostly parasitic on the roots of trees. 



1. EPIPHEGUS. Stems slender and bushy-branching, with small and scattered 



scales and two sorts of flowers, scattered in loose spikes or racemes, with 

 minute bracts. Upper flowers conspicuous, but seldonj ripening frait, with 

 tubular 4-toothed corolla, and long filaments and style ;'lowe» flowers small 

 and short, seldom opening, but fertilized in the hud. 



2. CONOPHOLIS. Stems thick, covered with fii-m overlapping scales, each of 



the upper ones with a flower in its axil, forming a spike. Calyx 4 - 6-toothe(l, 

 and split down on the lower side. Corolla short, strongly 2-lipped ; upper 

 lip arched and notched j lower one spreading and 3-cleft. Stamens pro- 

 truding. 

 8. APHYlXON. Stems are chiefly slender 1-flowered scapes from a scalv 

 mostly siibten-anean base. Calyx 5-cleft. Corolla with a long curved 

 tube, and a spreading slightly 2-li'pped or irregular 5-lobed border; the lobes 

 all nearly alike. Stamens included in the tube.
