africana, this species frequently 

 throws double spathes, as shown in 

 the sketch. There is a stocky variety 

 known as Rossi, and another called 

 " Mrs Roosevelt" having pale lemon- 

 yellow spathes. 



R. hastata. — This species grows 

 about 2 ft. high, and has oval 

 hastate pointed leaves, green and 

 unspotted. The spathes are of a 

 greenish-yellow and of good size. 

 {Bot. Mag. t. 5176.) 



R. intermedia. — A strong-growing, 

 compact, and free-flowering plant 

 with broadly heart-shaped leaves dot- 

 ted with white, and stalks i marbled 

 white and rose. Spathe very dark 

 yellow, with small black blotch at 



B. Lutwychel. — ^A species closely 

 related to R. hastata and R. Pent- 

 landi, having triangular, sagittate, 

 pointed, green unspotted leaves with 

 heavily spotted stalks. The spathes 

 are bright yellow with a large deep 

 purple blotch at the base. Now 

 considered to be identical with 

 R. hastata. {Rev. Hart. 1896, t. 

 60 ; Gard. Chron. 1893, xiii. 568.) 



R. macrocarpa. — This is recognised 

 by its very large fruits and medium- 

 sized spathes, pale green outside, 

 white within. 



B. melanoleuoa. — This species 

 grows about 2 ft. high, and has 

 oblong or oval sagittate-hastate leaves 

 covered with white translucent 

 blotches. The spathes are yellow, 

 enclosing a white spadix and having 

 a purple blotch at the base. (Bot. 

 Mag. t. 5765.) 



R. Pentlandl. — A fine species in 

 the way of R. Blliottiana, but with 

 larger, thicker, and unspotted green 

 leaves, and large bright golden- 

 yellow flowers (Bot. Mag. t. 7397; 

 Garden, 1895, ii. 1033). 



B. Rehmanni. — ^A little-known but 

 distinct species, having lance-shaped 



and rather small tubular 

 spathes tinted with dull rose-purple 

 (Bot. Mag. t. 7436). The variety 

 speciosa is dwarfer and stronger- 

 growing than the type, and the 

 spathe is bright red ; in the variety 

 coccinea the spathe is scarlet

Fig. 304. — Richardia ReTimcmni. Q.) 



{Gartenfl. 1906, t. 1552). This species 

 crossed with R. melanolevica has 

 produced a hybrid known as R. 

 cantdbrigiensis. 



B. Sprengeri. — This species from 

 the Transvaal is remarkable in having 

 leaves truncated (not hastate or 

 cordate) at the base, and the yellow 

 spathes are broader than in other 

 species {Gard. Chron,. 1902, xxxii. 

 350). /^
