upon the earth to be comparable to it." The Sundew was formerly much used aa 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 Droscra gi-ows. 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 plant. 

 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, wedgesliaped-oblanceolate or 

 strapsliaped-oblanceolate, gradually narrowed into long footstalks 

 Avliicli 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 chali'-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 laminae not 

 exceeding |- inch, and usually much less at the broadest jiai't, Avhich 

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

 so gradually into the footstalk that it is diflicult 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 arc about f inch across, and the petals and 

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

 capsule is mucli largei', more enlarged near tlie top, which 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.
