 base ; pinnae 6in. to 12in. long, lin. to 2in. broad, linear-oblong, 

 acuminate, entire, lower ones stalked. Japan, &c., 1863. Mr. 

 Baker considers this as "probably not really distinct from 

 G. javanica."^ There is a variegated form.

 tufted, fronds 2ft. to 2Jft. long, quadripinnate ; pinnae ascending, 

 triangular, very shortly stalked, upper surface pale green, lower 

 whitish. Supposed to be a hybrid between G. decomposita and 

 G. schizophylla. It is a plant of garden origin, recently raised by 

 Mr. W. B. Latham, Curator of the Botanic Gardens, Edgbaston. 



G. leptophylla (slender-leaved).* sti. lin. to 4in. long, fronds 

 2in. to 4in. long, lin. to liin. broad, ovate or deltoid, two or 

 three-pinnate ; segments cuneate-flabellate, cut into linear or 

 oblong lobes. Temperate regions throughout the world (Jersey). 

 Hardy. One of the very few annual ferns. 



G. macrophylla (large-leaved), rhiz. creeping, scaly, sti. 2in. 

 to 6in. long, fronds 1ft. to lift, long, Sin. to 4in. broad, narrowed 

 gradually to both ends, sori in single continuous or slightly 

 interrupted rows between the main veins. Malaya. 



G. Pearcei (Pearce's).* sti. 6in. to 9in. long, fronds about 1ft. 

 each way, deltoid, quadripinnatifid ; lower pinnae largest, 4in. to 

 6in. long ; pinnules imbricated ; one vein and sorus to each 

 ultimate division ; powder white. Peru, 1864. 



G. pulchella (neat), sti. tufted, 6in. to 9in. long, powdery. 

 fronds 6in. to 12in. long, 4in. to 6in. broad, tripinnatifld ; lower 

 pinnae largest ; pinnules imbricated ; segments flabellate-cuneate ; 

 powder pure white. Venezuela. The variety Wettenhalliana has 

 pale sulphur-coloured powder. 



G. rnfa (red), sti. tufted, 4in. to 12in. long, hairy, fronds 12in. to 

 18in. long, Sin. to 5in. broad, pinnate ; pinnae distant, stalked, 

 rounded, lin. to 2Jin. long; rachis pilose. Tropical America, 



FIG. 162. GYMNOGRAMME SCHIZOPHYLLA. 



G. schizophylla (cut-leaved).* sti. tufted, slender, fronds lift, 

 to 2ft. long, gracefully arching, very finely cut ; ultimate pinnules 

 minute. Jamaica, 1880. See Fig. 162. 



G. s. glorlosa (glorious). A garden variety, of more vigorous 

 habit than the type. (I. H. 522.) 



G. sulphurea (sulphur-coloured).* sti. densely tufted, lin. to 6in. 

 long, often powdery, fronds 6in. to 12in. long, Sin. to 4in. bvo.T 1 

 tripinnatitid ; lower pinnae gradually reduced ; pinnules *' 

 lately cut ; powder bright yellow. West Indies, 1808. 



G. tartarea (infernal).* sti. tufted, 6in. to 12in. Ions', frond* 1ft. to 

 2ft. long, 6in. to 12in. broad, oblong-deltoid, bipi pinn 



lanceolate, lowest largest ; pinnules oblong, obi 

 nearly so ; powder dense, pure white. Tropical .

FIG. 163. GYMNOGRAMME TARTAREA. 



See Fig. 163. There are three or four varieties, including ochracea 

 (pinnules very regular, and only the lowest toothed ; powder 

 bright yellow), ornithopteris, and Steltzneri. 



G. tomentosa (tomentose). sti. tufted, 6in. to 12in. long, villose.

GYMNOGYNOUS. Having a na.ked ovary. 



GYMNOIiOMIA (from gymnos, naked, and loma, a 

 fringe ; in reference to the pappus being much reduced 

 or altogether absent). SYNS. Qymnopsis and Heliomeris. 

 OKD. Composites. An interesting genus, containing six- 

 teen species of erect greenhouse or half-hardy herbs, na- 

 tives, for the most part, of Mexico and Central America. 

 Flower-heads pedunculate, solitary or loosely corymbose. 

 Inferior leaves rarely almost all opposite, superior ones 

 rarely almost all alternate, entire, dentate or lobed. The 

 species described below is the one usually seen in cul- 

 tivation. For culture, see Helianthus.
