INCARVILLEA. — A genus of modern introduction, 

 natives of China. The first species was Delavayi, and 

 it made considerable stir, for its foliage is distinct and 

 handsome, and the flowers, which somewhat resemble 

 a small Gloxinia, are bright crimson. It was, and is, 

 a grand plant, but the newer grandiflora is better still, 

 for the flowers are finer, and on shorter stems. It 

 may be expected to grow in favour rapidly ; the colour 

 is carmine. It is probably a variety of Delavayi, 

 The Incarvilleas are not coarse or spreading plants, and 

 although the flower spikes are rather long, they are 

 quite suitable for the rockery. They like a friable, 

 gritty loam. Propagation is easily effected by sowing 

 seeds under glass in spring, or by dividing the crowns. 

 A mulching of dry grit is good in autumn. Manure 

 should not be used as it might injure the crowns. 



lONOPSIDIUM ACAULE.— One of the smallest 

 of flowering plants, growing only an inch or two high, 

 it is nevertheless really beautiful, for it forms a dense 

 cushion which it covers with pretty violet flowers. 

 It is an annual, and may be sown out of doors in 

 spring to cover any bare patches of soil on the 

 rockery. It will bloom in a few weeks, and form 

 a dainty carpet.

LEONTOPODIUM ALPINUM.—See Edelweiss. 



LEUCOJUM (Snowflake). — The pretty Spring 

 and Summer Snowflakes are charming bulbs and may 

 be introduced to the rockery if desired, associated with 

 a carpeter such as the Herniaria or a mossy Saxifrage. 

 The Spring Snowflake (L. vernum) resembles the Snow-
