TOLMIEA. — A genus closely related 

 to Heuchera and differing in having only 

 3 stamens. The only species described 

 below requires the same treatment as 

 Heuchera and Tiarella, both of which 

 names it bore at one time. 



T. Menziesi. — A native of N.W. 

 America, having stems 1-2 ft. high, with 

 3-5 hairy leaves, lower ones stalked, 

 incised, lobed. Flowers in April, green- 

 ish, rather large, nodding in a slender 

 -elongated raceme, calyx purple-nerved. 



Culture dc. as above for Heuchera. 

 It ilourishes in ordinary well-drained 

 garden soil and may be increased by 

 division or seeds. 



PARNASSIA (Grass or Paenassus). 

 A genus with twelve species of elegant, 

 very smooth, scapigerous herbs, with 

 radical, ovate-kidney-shaped or oblong 

 leaves, with stalks dilated at the base. 

 Scapes angled, 1-flowered. Calyx lobes 5. 

 Petals 5, entire or fimbriated. Stamens 

 6, hypogynous or perigynous, alternating 

 with 5 more or leas club-shaped and 

 •divided, glandular tipped scales or stami- 

 nodes. Ovary superior or half inferior. 

 Style 1, very short, with 3-4 stigmas. 



Culture and P'l-ojpagaiion. — Parnas- 

 «ias thrive in a moist peaty soil in the 

 rockery, or in the bog-garden. They may 

 be increased by division in early autumn, 

 ■or in spring as growth is about to com- 

 mence ; or from seed sown as soon as ripe 

 in cold frames, afterwards pricking the 

 seedlings out into light soil when large 

 enough. 



P. asarifolia. — A very pretty North 

 American plant, 6 in. high, with more or 

 less kidney-shaped leaves and white 

 flowers in summer. 



Culture dc. as above. 



P. caroliniana. — A native of North 

 American swamps, 6-9 in. high. Leaves 

 roundish below, ovate above. Flowers 

 from July to September, white, netted with 

 green or purple. 



Culture dc. as above. 



P. iimbriata. — A remarkable plant, 

 C in. high, native of N. America. Lower 

 leaves kidney-shaped, hollowed out at the 

 base and lobed or divided. Flowerg in 

 July, white, petals obovate, clawed, 

 fi'inged at the base. 



Culture dc. as above. 



P. nubicola. — A Himalayan species 

 with elliptic, rather heart-shaped leaves. 

 Flowers in summer, white, solitary, over 

 an inch across, borne on 4-angled stalks 

 6-12 in. high, and having 3-lobed yellow 

 staminodes. 



Culture dc. as above. 



P. palustris {Common Grass of Par- 

 nassus). — A lovely httle bog plant, about 

 in. high, native of the British Islands. 

 Leaves heart-shaped rounded. Flowers 

 in summer, |-1 in. across, white, with 

 greenish peUucid veins. 



Culture dc. as above. 



P. parviflora. — A native of N.America, 

 6 in. high, with ovate leaves. Flowers in 

 July and August, white, net-veined with 

 pale purple or green. 



Culture dc. as above. 



Tribe II. Francoe^. — Scapigerous herbs with parts of the flowers in fours 

 •(tetramerous). Stamens 4 or 8. 



FRANCOA (Maiden's Wreath).— A 

 genus with two or three species of Chilian 

 perennials beset with glandular hairs or 

 down, and with thick fleshy rootstocks. 

 Leaves crowded, lyrate-pirmatifid, or 

 pinnate, glandular-toothed, net-veined. 

 Flowers in long, more or less erect or 

 arching racemes. Calyx lobes, petals, 

 and stamens 4. Ovary free, 4-angled or 

 lobed. 



Culture and Propagation. — Francoas 

 thrive in a rich, light, loamy soil, but can 

 be grown out of doors (except in summer) 

 only in the very mildest parts of the 

 country, and they should have dry sheltered 

 positions on warm banks or borders. The 

 .spUces of flowers, often over 2 ft. long, are 



excellent for cutting and last a long time. 

 Seeds must be raised in a hotbed or 

 greenhouse, and may be sown in early 

 spring. Afterwards prick out separately 

 into small pots and grow on until large 

 enough for putting out or growing in larger 

 pots. The plants may also be increased 

 by dividing the rootstock in spring or early 

 autumn. 



F. appendiculata. — A lyrate-leaved 

 plant 1 -2 ft. high. Flowers in July, pale 

 red, with a deeper spot at the base of each 

 petal, in compact racemes on nearly 

 simple scapes. 



Culture dc. as above. 



F. ramosa. — This species has a stem, 

 and shortly stallced, usually deourrent
