PB ACTIO AL GUIDE TO GABDEN PLANTS chimaphila 



PYROLA (Winter Green). — A genus 

 containing about 14 species of smooth, 

 stolon-bearing, stemless or caulescent 

 perennials. Leaves radical or cauline, 

 alternate, often long-stalked, persistent, 

 entire or serrate. Flowers nodding, on 

 erect racemose scapes. Calyx 5-parted. 

 Petals 5, concave. Stamens 10, hypogy- 

 nous, erect or bent down. Ovary 5-ceIled. 



Culture and Propagation. — Pyrolas 

 flourish in half-shady places in the rockery 

 or border, in light moist sandy soil, with 

 plenty of leaf mould or other vegetable 

 matter. They may be increased by seeds 

 sown as soon as ripe in the open border or 

 cold frames, or in spring ; or by dividing the 

 plants in early autumn or spring. 



P. elliptica. — A rather rare North 

 American species about 6 in. high. 

 Leaves leathery wedge-shaped oblong, 

 remotely toothed or entire. Flowers in 

 June and July, white, beU-shaped, in long 

 one-sided racemes. 



Cultitre dc. as above. 



P. rotundifolia. — A British plant about 

 6 in. high. Leaves roundish, entire or 

 slightly crenulate, with dilated stalks. 

 Flowers from July to Septeraber, pure 

 white, A in. across, fragrant, 10-20, nod- 

 ding on an erect scape. The variety are- 

 naria has smaller leaves than the type, 

 and several scaly bracts below the flowers. 



Culture Sc. as above. 



P. secunda. — A rare native of the 

 British Islands and the N. temperate 

 zone, with straggling stems 1-4 in. long. 

 Leaves ovate acute serrate, 1-1 a in. long. 

 Flowers in July, greenish-white, j in. 

 across, horizontal, on one-sided slender 

 scapes 2-5 in. long. 



Culture dc. as above. 



Other British species are media with 

 white flowers ; minor having white flowers 

 tinged with rose ; and uniflora (or 

 Moneses granddfiora) also with white 

 blossoms. 



CHIMAPHILA. — A genus with 4 

 species of -sery smooth stolon-bearing 

 perennial herbs. Leaves stalked, some- 

 what whorled or distant, fleshy, persistent, 

 shining, serrate. Flowers in terminal 

 corymbs, rarely solitary, fragrant. Calyx 

 5-lobed or parted. Petals 5, roundish, 

 concave, spreading or reflexed. Stamens 

 10, dilated and hairy at the middle. 

 Ovary roundish 5 -celled. 



C. corymbosa (Pyrola umbellata). —A 

 native of the N. Hemisphere 3-6 in. high. 

 Leaves cuneate lance-shaped, serrate, 

 4-5 in a whorl. Flowers in June, greenish- 

 white, tinged with red. 



Culture and Propagation. — This is 

 practically the same as for Pyrola de- 

 scribed above. The Chimaphilas are 

 suitable for damp, half-shady parts of the 

 border or rock garden, and will flourish in 

 ordinary good sandy soil, to which leaf- 

 mould or peat has been freely added. The 

 plants may be increased in early autumn or 

 spring by dividing the roots ; or seeds may 

 be sown when ripe or in spring in sheltered 

 parts in the open border or in cold frames. 



C. maculata (Pyrola). — A rather pro- 

 cumbent N. American species, with lance- 

 shaped acute leathery leaves opposite or 4 

 in a whorl, striped with white above, red 

 beneath. Flowers in June, white, droop- 

 ing, on downy stalks. 



Culture dtc. as above for C. corymbosa. 



CLETHRA. — A genus containing 

 about 25 species of downy or wooUy trees 

 and shrubs. Leaves sparse, persistent or 

 rarely deciduous, stalked, entire, serrate 

 or toothed. Flowers in racemes or pani- 

 cles near the ends of the branches, rarely 

 in corymbs or clusters. Calyx deeply 

 5- lobed or parted. Petals 5, obovate 

 wedge-shaped, rounded at the apex, or 

 2-lobed, often erose. Stamens 10. Ovary 

 round, 3-ceIled, 3-angled or lobed, downy 

 or hairy. Capsule roundish, small, usually 

 nodding. 



Culture and Propagation. — Clethras 

 flourish in the mild southern parts of 

 England and Ireland, and enjoy a mixture 

 of peat and sandy loam in moist places. 

 They may be increased from seeds care- 

 fully sown when ripe, or in spring, on the 

 surface of fine sandy peat soil, and 

 covered with a sheet of glass ; by layering 

 the stems in autumn, or by insertmg cut- 

 tings of the half-ripened shoots in sandy 

 soil under a bell-glass in gentle heat, or a 

 cold frame, shaded from the sun during 

 the summer months. 



If a practice were made of raising these 

 plants from home-saved seed, it would 

 probably have the effect of producing a 

 much hardier race that would stand the 

 winters in most of the milder parts of the 

 kingdom. 



C. acuminata. — A native of Carolina, 

 10-15 ft. high, with smooth, oval, pointed
