GARDEN BOTANY. lxiil 



stalks, and one-flowered scapes, on the apex of which the graceful flower is 

 recurved, so that the reflexed divisions of the corolla turn up ; this is rose- 

 colored or white with a pink base. 



3. Lysimachia, Loosestrife. Man. p. 272. Two species are com- 

 monly met with in gardens : — 



L. nummularia, Moneywort. Smooth, creeping over the ground 

 and rooting, with opposite small orbicular leaves, and solitary axillary light- 

 yellow flowers. It flourishes in moist places, and is often grown in hanging 

 pots. 



L. vulgaris, English Loosestrife. A stout perennial, more or less 

 downy, with whorls of ovate-lanceolate leaves and a leafy panicle of deep- 

 yellow flowers. In old gardens. 



4. Anagallis arvensis, Pimpernel. Man. p. 274. The common red 

 variety is frequent in gardens ; the larger blue one is choicer. 



Order GESNEB,IACE.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 Orobanchacese, Man. p. 279, but with green herbage, and not 

 parasitic, — and the common cultivated species have the tube of the calyx co- 

 herent at least with the base of the ovary. Many, and some very showy, plants 

 of this order are in the conservatories ; the commonest are the following, all 

 perennials. 



1. Gloxinia speciosa. An almost stemless herb, with ovate and crenately 

 toothed leaves and 1 -flowered scape-like peduncles; the corolla deflexed or hor- 

 izontal, 2' lonjr, ventiicose, between bell-shaped and funnel-form, gibbous, with 

 a short and spreading, somewhat unequal, 5-lobed border, pale violet with a 

 deeper-colored throat, in one variety altogether white. 



2. Gesneria zebrina. Stem tall, leafy ; leaves petioled, cordate, velvety, 

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

 corolla tubular-vcutricose, 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. 



3. Aehime'nes longiflora. 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 very flat 5-lobed limb 2' or more broad, 

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

 from the root. 



Order BIGNONIACEJE. Bignonia Family. 



Manual, p. 277. — The following are common ornamental exotics : — 



1. Tecoma grandiflora, Great-flowered Trumpet-Creeper. Like 

 our T. radicans, but less hardy, therefore less climbing, and with a larger but 

 proportionally shorter orange-red corolla, its proper tube scarcely exceeding 

 the calyx. 



T. Capensis. A bushy greenhouse species, with the flowers crowded, 

 the red-orange corolla tubular and curved, the stamens exserted. 



T. jasminoid.es. A fine greenhouse species, twining, very smooth, 

 with the leaflets pinnate, lance-ovate, entire, bright green ; corolla white, pink- 

 purple in the throat
