PRACTICAL GUIDE TO GARDEN PLANTS 



LAYIA 



shaped, the upper ones being entire, while 

 the lower ones are pinnately divided. The 

 flower-heads, each about IJ in. across, 

 appear in summer, and have broad 

 3-toothed ray florets of a golden-yellow 

 colour at the base, and white towards the 

 apex. 



Culture Sc. as above. 



L. glandulosa. — A much-branched 

 Californian annual about 18 in. high, 

 covered with glandular hairs throughout. 

 The blunt linear leaves are 1-lJ in. long, 

 and the flower-heads, which appear in 

 summer, are about an inch across, the 

 3-lobed wedge-shaped ray florets being 

 white, and the disc florets yellow. 



L. heterotricha seems to be closely 



Tribe VI. Helenoide*:. — Leaves opposite or alternate, entire, toothed, or 

 variously cut. Disc florets yellow, rarely white, purple, or violet. Bay florets strap- 

 shaped, entire or 2-3-toothed. Bracts of the involucre usually in 3 series. Eeceptacle 

 naked or slightly pitted. 



related to this species. It has white ray 

 florets and a yellow disc. 

 Culture dc. as above. 



L. platyglossa (CalUchroa ^jteij/- 

 fflossa). — A pretty downy Californian 

 annual 6-12 in. high, with lower leaves 

 stalked and in rosettes, those on the stems 

 being alternate and sessile, but all except 

 the uppermost lance-shaped and deeply 

 toothed. The long-stalked flower-heads 

 appear during the suromer months and 

 have deep yellow ray florets with 3 or 4 

 teeth at the apex, and arranged in a single 

 ring rotmd the yellow disc, which becomes 

 brown with age. 



Culture Sc. as above. 



BiSRIA. — A genus containing 4 or 5 

 species of smooth or hairy, often diffuse 

 annual herbs with opposite, Hnear, entire, 

 pinnately cut or divided leaves. Flower- 

 heads yellow at the ends of the branches 

 and long-stalked in the axils of the upper 

 leaves. Involucre broadly bell-shaped or 

 hemispherical. Receptacle conical, naked. 

 Achenes linear or narrowly wedge-shaped, 

 smooth or hairy. 



Culture and Propagation. — Bserias 

 grow readily in ordinary boU, but look 

 effective only when grown in large patches. 

 The individual flowers are not very large, 

 lees than 1 in. across, but they are 

 produced in great profusion, almost en- 

 tirely covering the plant. Seeds may be 

 sown in gentle heat about March, and the 

 seedlings planted out in June. Seeds may 

 also be sown in patches in the open border 

 where the plants are to bloom, but it will 

 be necessary to thin the seedlings out so 

 as to allow those left plenty of space to 

 develop. 



B. chrysostoma. — A Californian annual 

 about 1 ft. high, with linear, opposite, 

 entire leaves, and masses of bright yellow 

 flowers in summer. 



Ctdture Ac. as above. 



B. coronaria (Hymenoxys californica ; 

 Shortia- californica). — A pretty Califor- 

 nian annual having trailing stems with 

 lance-shaped acute leaves, deeply cut into 

 linear pointed segments. Flower-heads 

 brilliant yellow, about an inch across. 



Culture (Be. as above. Owing to its 

 trailiag habit this plant barely exceeds 

 2-3 in. in height, and looks weU in masses 

 in flower borders during the summer. It 

 has been wrongly referred to the genus 

 Shortia, whichis described at p. 600, and be- 

 longs to a quite different family of plants. 



B. gracilis. — A Californian annual 

 6-10 in. high, with opposite linear leaves, 

 and bright yellow solitary flower-heads 

 about I in. across. 



Culture dc. as above. 



LASTHENIA. — A genus with only 

 three species of smooth slender-growing 

 annuals, having opposite linear entire 

 leaves, and long-stalked, often nodding 

 yellow flower-heads. 



L. glabrata {L. californica). — A 

 pretty Californian annual 9-18 in. high, 

 with linear leaves occasionally with a 

 tooth or lobe on each side. The bright 

 yellow flower-heads appear during the 

 summer months, and are borne on downy 

 stalks. 



Culture and Propagation. — This 

 plant flourishes in ordinary garden soil, 

 and is effective when grown in bold 

 masses. Seeds may be so^\'n when ripe 

 in the open border or cold frames in 

 autumn, and again about April so as to 

 keep up ii succession of blossom. When 

 sown out of doors the seedlings should be 

 thinned out and not transplanted. 



BAHIA. — A genus containing about 

 20 species of undershrubs, bushes, or
