Native of Porto-Rico and St. Domingo. Flowers purple, 3 to

Serrated-leaved Riedleia. Pl. 1 to 2 feet. o 
Cult. Riedlèia is a genus of plants not worth cultivating ex- 
cept in botanic gardens; they will thrive well in any light rich 
soil, and cuttings of the shrubby and herbaceous perennial kinds 
will root freely in sand under a hand-glass, in heat, but this will 
in most cases be unnecessary, as the greater part of the species 
ripen seed freely in this country; these require to be sown in 
pots in spring, and placed in a hot-bed, as well as those of the 
annual species, and when the plants are of a sufficient size they 
should be potted off into separate pots, and placed in the stove. 
XVI. WALTHERIA (in honour of Augustus Frederick 
Walther, a German botanist, once professor of medicine in the 
university of Leipsic; he described the plants of his own garden 
in 1735. Itis also understood to commemorate Thomas Walter, 
an English botanist, author of Flora Caroliniana in 1798, and 
Richard Walter, who went round the world with Admiral An- 
son in 1740 and 1744.) Lin. gen. no. 827. D.C. prod. 1. p.

W. Indica, Jacq. icon. rar. 1. t. 130. ‘There is a variety of 
this plant which bears sessile heads of flowers, and perhaps not 
distinct from W. I'ndica; and there is also another variety with 
elongated peduncles, bearing as if it were many concatenated 
bundles of flowers. Flowers yellow.
