GESNERACE2E. A natural order of herbs or shrubs, 

 rarely trees, often growing from scaly tubers. Flowers 

 showy; corolla variously coloured, often scarlet, violet, 

 or blue, rarely white ; calyx half adhering, five-parted ; 

 stamens two or four. Leaves opposite; usually wrinkled. 

 There are about seventy-one genera and 700 species, 

 natives of various parts of the world, chiefly the warmer 

 regions of America. Sometimes the name Cyrtandraceai 

 is given to this order. Illustrative genera are : Achimenes, 

 Besleria, Cyrtandra, Gesnera, Gloxinia, and Streptocarpus. 



GESNERIA. See Pentarhaphia. 



GETHYLLIS (an old Greek name, a diminutive 

 of gethuon, a leek). ORD. Amaryllidece. A genus of four 

 or five species of pretty dwarf greenhouse bulbous peren- 

 nials, from the Cape of Good Hope, allied to Sternbergia. 

 Flowers white, delicionsly fragrant ; perianth tube long, 

 cylindrical ; limb of six segments, regular and spreading ; 

 scapes short, one-flowered. Leaves linear. The plants 

 thrive best in a mixture of sandy loam and peat; they 

 may be increased by offsets, or by seeds. But few of 

 the species have been introduced. 



G. ciliarls (fringed), fl. white ; sepals ovate-oblong. June and 



July. I. linear, spiral, ciliated, h. 6in. 1788. 

 G. lanceolata (lance-shaped), fl. white ; sepals lanceolate. June. 



I. lanceolate, flat. A. 9in. 1790. 

 G. spiralls (spiral). /. white ; sepals ovate-oblong. June and 



July. 1. linear, spiral, smooth, h. 9in. 1780. (B. M. 1088.) 

 G. villosa (hairy), fl. white ; sepals ovate-oblong. June and 



July. I. linear, filiform, spiral, villous. h. 9in. 1787. 



GEUM (the old Latin name used by Pliny). Avens. 

 Including Sieversia. Some of the species were formerly 

 placed under a genus named, Adamsia. ORD. Rosacece. 

 A genus comprising about thirty species of hardy peren- 

 nial herbs, widely diffused over all temperate and cold 

 regions. Flowers yellow, red, or white, growing singly on 

 long peduncles, at the ends of the stems or branches; 

 petals five. Leaves variously dissected, the terminal lobe 

 always the largest. Genms are of very easy culture, in 

 moderately good soil, and in a well - drained situation. 

 Most of tho species are well adapted for growing in 

 borders and in the rock garden. Propagated by seeds, 

 or by division. 



G. chiloense (Chiloe). fl. scarlet, sometimes copper - coloured, 

 panicled, erect. Summer. I., radical ones interruptedly pin- 

 nate ; leaflets crenately serrated, the terminal one large, cordate, 

 lobed, and crenated ; cauline ones three - parted, deeply cut. 

 Stem glandular, h. 1ft. to 2ft. Chiloe, 1826. Plant viilous.
