Lower part of the steyn immersed in loose earth, or dead leaves,

 ering branches terminal, solitary, erect, 4 or 5 inches high,

 ieaDesovate, thick, juicy, entire, smooth, cream-coloured; closely 

 imbricated on the lower part of the stem; more loosely on the 

 flowering branches. FL axillary, solitary, stalked, drooping, 

 rather longer than the leaves. Cal. of the hue and texture of 

 the leaves ; hairy at the base ; segments smooth, incurved, the 

 2 uppermost largest. Cor. of a pale dull purple, with a white 

 tube, about as long as the limb ; upper lip deeply cloven. Anth. 

 large, hairy. Caps, large, thin, crowned by the withered style, 

 and invested with the permanent calyx. 



The analogy of the preceding genus helps us to understand the 

 herbage of this singular plant, and proves what is usually taken 

 , for roots to be a partly subterraneous stem. The real root is, I 

 believe, fibrous and parasitical. Thejloral leaves agree with the 

 rest, as in Melampymm sylvaticum. L, Clandestina has also ax- 

 Wlary Jiowers, from a subterraneous herbage.
