RIGIDELLA 



a/ncana, this species frequently 

 throws double spathes, as shown in 

 the sketch. There is a stocky variety 

 known as Jxossi, and another called 

 ''Mrs Booserelt,''' 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. 

 (Jht. Mnij. t. 5176.) 



R. intermedia. — A strong-growing, 

 compact, and free-flowering plant 

 ■with broadly heart-shaped leaves dot- 

 ted with white, and stalks marbled 

 white and rose. Spathe very dark 

 yellow, with small black blotch at 

 base. 



R. Lutwychei. — 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. Ilort. 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. 



R. melanoleuca. — 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 svhite spadix and having 

 a purple blotch at the base. {Hot. 

 Marj. t. 5705.) 



R. Pentlandi.— A fine species in 

 the w^ay of R. Elliottiana, but with 

 larger, thicker, and unspotted green 

 leaves, and large bright golden- 

 yellow flowers {hot. Matj. t. 7397; 

 Garden, 1895, ii. 1033). 



R. Rehmanni.— A little-known but 

 distinct species, having lance-shaped 



leaves, and rather small tubular 

 spathes tinted with dull rose-purple 

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

 spen'osa is dwarfer and stronger- 

 growing than the type, and the 

 spathe is bright red ; in the variety 

 coccinea the spathe is scarlet

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

 crossed wdth R. melanoleuca has 

 produced a hybrid known as R. 

 ca nta h rigiensis. 



R. 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).
