CALCEOLARIA CALTH A. 



Calceolaria Kellyana (Kelly's C.) 

 A handsome hardy hybrid, with 

 twice-branching downy stems, 6 in. to 

 9 in. high. Flowers, in summer; nearly 

 f in. across, deep yellow with nume- 

 rous small brown dots, two or three 

 together on the top of the stems. 

 Leaves, all radical, in a rosette, almost 

 spathulate in shape, with an irregular 

 toothed margin, and more or less 

 covered on both sides with soft white 



hairs. Rockwork and borders, in 



well-drained sandy loam. Division. 



Calla palustris (Bog Arum}. A very 

 interesting and ornamental trailing bog- 

 plant, 3 to 8 in. high. Flowers, in 

 summer ; spadix yellow, half as long 

 as the spathe, which is persistent, 

 flat, oval - obtuse, with a terminal 

 point, pure white on the inside, and 

 greenish externally. Leaves , all radical, 

 oval or heart-shaped, stalked, the 

 stalks sheathing the stem at the base. 

 Rhizome, thick, creeping, jointed. 

 Marshes in the N. E. of France, N. 

 Europe, N. Asia, and N". America. 



Grows freely in every kind of 



bog, natural or artificial, and by the 

 margins of ponds and lakes. I have 

 never seen it so luxuriant as on beds 

 of rich soft mud. Easily increased 

 to any extent by division of the long 

 creeping rootstock. 



Calliprora lutea (Yellow C.) A 

 rather pretty bulbous plant. Flowers, 

 in early summer ; yellow ; divisions 

 purplish-brown in the middle on the 

 outside. Leaves, linear-sword-shaped, 

 pointed, grooved, longer than the 

 flower-stem; bracts sheathing, sca- 

 rious, much shorter than the pedicels, 



Native of N. California. The bulb 



border, or a well- drained spot on the 

 lower flanks of rockwork, in dry sandy 

 soil. Separation of the bulbs. 



Callirhoe digitata (Finger-leaved C.) 

 A glaucous herb, 2 to 3 ft. high. 

 Flowers, in summer ; reddish purple ; 

 peduncles long, axillary, 1 -flowered. 



Leaves, subpeltate, 6 to 7 -parted ; seg- 

 ments, linear, entire or 2-parted ; up- 

 per ones more simple. North America. 



Borders, or rough rockwork, in 



richfibry loam. Seed, or careful division. 



Callirhoe involucrata (Crimson Mal- 

 va). A very handsome procumbent 

 herb, 6 in. high. Flowers, in summer, 

 crimson, 14 to 2 in. across, in a loose 

 panicle ; sepals lance -shaped, very 

 hairy ; stalks erect, 1 to 2 in. long. 

 Leaves, divided nearly to the base, 3 

 to 5-parted ; segments narrow, lance- 

 shaped, 3 to 5-toothed, hairy on both 

 sides ; stem clothed with spread- 

 ing hairs. Valley of the Loup, Fork 



of the Platte, N. America. Sunny 



borders, or rockwork, in good sandy 

 loam. Seed. 



Calluna vulgaris (Common Ling). 

 Erica vulgaris. --A well-known spread- 

 ing evergreen shrub, 1 to 2 ft. high 

 or more. Flowers, in summer ; pur- 

 plish-pink, small, in long, terminal, 

 spiked racemes. Leaves, 3 -cornered, 

 small and short, opposite, blunt at the 



point, arrow-shaped at the base. 



Few of us would think of giving a 

 place to the common Ling, but several 

 of its dwarf and highly - coloured 

 forms deserve a place on the rougher 

 parts of the rockwork, or in beds in 

 tufts, or as edgings, in a peat soil. 



Calopogon pulehellus (Pretty C.} A 

 very attractive tuberous- rooted orchi- 

 daceous plant, about 1 ft. high. 

 Flowers, late in summer ; purple, with 

 a handsome pale- ye] low beard or tuft 

 of hairs growing from the lip. Leaves 

 few, radical, grassy. Native of all 

 parts of the United States, in wet 

 prairies, or the edges of pine woods. 



Well suited for a good position on 



the rockwork, or for an open spot in 

 the hardy fernery. I have had no expe- 

 rience of the mode of propagating it. 



Caltha palustris (Marsh Marigold]. 

 A well-known native plant with 

 slightly branched stems, 6 to 12 in.
