 from which genus it is principally distinguished by the capsule 

 dehiscing laterally, by the style being tubular at top, and some-

 placentas in both valves being solitary and very distant.

 extremity of the root ; upper parts of the branches producing 

 perfect flowers, but abortive fruit ; lower imperfectly formed 

 flowers fructiferous. Capsule coriaceous and small, the cha- 

 racter of Melampyrum, but truncated, and at length extending 

 by moisture in the form of a cup.

1 L. CLANDESTI'NA (Lin. spec. 843.) stem branched almost 

 under the earth; flowers erect, solitary, y.. H. Native of 

 Europe, in shady places, parasitical on the roots of trees, as of 

 France, Pyrenees, and Italy. D. C. fl. fr. 3. p. 491. Lam. ill.

 3. p. 503. sect. 12. t. 16. f. 15. The stem bears a corymb 

 under ground, so that solitary flowers only appear above ground 

 on each branch. Flowers large, blue. This is probably a very 

 distinct genus from the following.

 ers spicate, unilateral, disposed in 2 rows ; corollas pendulous. 

 "H. . H. Native of most parts of Europe, in woods, parasitical 

 on the roots of trees, as elms, hazels, beech, generally almost 

 covered by the fallen leaves ; plentiful in some parts of Britain ;
