through, but each stem and leaf bordered with a sliiiiing silvery 

 halo from tlie drops of li()[uid on the glands. 



The plant is usuall}^ about 15 inches in height, but I noticed 

 several of 20 to 25 inches. The stem is stout and branchiiiir. 

 The plant is greenish-yelh>\v in all its parts, save that in young 

 leaves about 1^ inches of the tip is crimson. The leaves vary 

 from 4 to 8| inches in length, and are three-sided, but with the 

 angles rounded, and bearing a round knob at the apex. The 

 flower is large, bright magenta in colour, the bright yellow anthers 

 forming a striking contrast. At a distance it reminded me of 

 Cheira/iithera linearis in shape and coloration. Examined more 

 closely, it bears little resemblance to the more open cup-shaped 

 flowers of the Droseraceie generally. A specimen with pure 

 white flowers was shown to me by Miss Prinsep, who collected it 

 in the same locality. The; flowers have been described as salmon- 

 coloured, but I saw none approaching that hue. There is a very 

 good figure in a recent part of Curtis' ' Botanical Magazine' (1)- 



The stem, leaves, flower-stalks and calyces were all thickly 

 covered with glands, which had captured large numbers of insects, 

 among which I observed ants, small flies and mosquitoes, and a 

 few moths and bugs. 



The glands, as Darwin pointed out (2), are of two kinds — long- 

 stemmed and sessile. Both kinds are found in all parts of the 

 plant above ground, except the corolla and its internal whorls. 



The pedicellate glands (PI. xxxvii., figs. 1 and 2) are about 

 0-018 mm. high, the stalks being slender, thin-walled, hollow and 

 unicellular. There is in many a marked constriction or neck just 

 where they join the head. The head is flat and circular, 0"003 

 to 0*005 mm. in diameter, and divided into a large number of 

 wedge-shaped cells radiating from the centre (fig. 10). The 

 epidermis forms a pocket of large flat cells (fig. 3) under the base 

 of the pedicel. Darwin says of the pedicels (2) : — " The walls are 

 marked with fine intersecting spiral lines, and the pedicel often 

 spirally rolled up." His specimen was dried. I was unable to 

 detect the spiral lines in spirit specimens, and the pedicels were 

 collapsed in all sorts of irregular shapes. But on examining a
