upon the earth to be comparable to it." The Sundew was formerly much used as a 

 tincture, to obtain which it was distilled with wine and then spiced and sweetened. In 

 this way a most stimulating spirit was produced, and the plant is still employed in the 

 manufacture of the Italian liqueur " rossoli." There is a notion in some parts of the 

 country that a disease called " red rot" in sheep is produced by this plant; but as those 

 animals never eat it, the complaint can only be the result of the miasma arising from the 

 marshy and boggy ground on which the Drosera grows. The anatomy of the hairs of the 

 leaves of the Sundew will well repay the attention of the microscopic observer. These 

 hairs are an exception to the general structure of the hairs of plants, which are com- 

 posed entirely of cellular tissue, and are a development of the epidermis of the jilant. 

 It will be found, however, that the hairs of the Sundew contain in their interior spiral 

 vessels, so that they are prolongations of the fibre- vascular portion of the leaves, and not 

 of their cellular part only.

Leaves ascending or sub-erect, weclgesliaped-oblanceolate or 

 strapsliaped-oblanceolate, gradually narrowed into long footstalks 

 which are glabrous. Scapes much longer than the leafstalks, erect 

 from the very base. Capsule longer than the sepals, pyriform- 

 ovoid. Seeds fusiform, with a loose reticulated chaff-like testa. 



On wet heaths. Not uncommon in the North and West of 

 Scotland, becoming more rare in the East ; and apparently absent 

 from the South-East of England, where the counties of Norfolk, 

 Bedford, Somerset, Devon, and Glamorgan appear to be the limits. 



England, Scotland, Ireland. Perennial. Late Summer 



and Autumn. 



Hootstock vertical, slender, producing a short stem bearing leaves 

 and scapes which appear to be radical. The leaves, including the 

 leafstalks, are from 2 to 4 inches long and erect ; the laminte not 

 exceeding \ inch, and usually much less at the broadest part, which 

 is a little way aliove the abruptly-rounded tip, while the base tapers 

 so gradually into the footstalk that it is difficult to say where the one 

 begins and the other ends. The scapes are considerably taller than 

 the leaves, from 4 to 8 inches high. The flowers much resemble those 

 of D. rotundifolia, but are about f inch across, and the petals and 

 other parts of the flower are often more than 5 in number. The 

 capsule is much larger, more enlarged near the top, whicli protrudes 

 a little beyond the calyx, and is almost as long as the withered petals. 

 Seeds similar to those in D. rotundifolia, but with a more loosely- 

 reticulated seed-coat. 



D. obovata (Mert.) is stated by Professor Babington to be
