JDrosera serpens Planch. I. c. 



Annual, with short fibrous roots. Stem simple, usually erect, or decum- 

 bent, narrow, minutely pubescent, attaining 24 cm. in length. Leaves sparse, 

 often spreading, or sometimes reflexed, angustato-linear, acuminate, attain- 

 ing about 9 cm. long including the petiole, very piloso-pubescent with long 

 delicate glandular hairs on the upper surface, pale green ; petiole not long, 

 glabrous, indistinct from the blade. Raceme leaf-opposite or produced 

 between leaves on the opposite side of them, often longer than the leaves, 

 spreading, laxly 2-9-flowered, rachis slender, minutely pubescent ; bracts 

 minute, filiform. Flowers pedicellate, about 9 mm. across, rosy (/. rosea) or 

 white (/. albifiora) ; pedicels spreading, minutely pubescent, 4-13 mm. long. 

 Calyx 5-parted ; segments subulato-lanceolate, tapering, minutely pubescent. 

 Petals 5, patent, longer than the calyx, spathulato-oblong. Stamens 5, 

 about as long as the calyx. Ovary obovoid-oval ; styles 3, parted into 2 

 long filiform branches, long-stigmatiferous above. Capsule oval-ellipsoid, 

 hardly shorter than or equal to the persistent calyx, 1-celled, dehiscent into 

 3 1-placentiferous valves. Seeds black, obovoid ; testa prominently scalari- 

 form-reticulated. Flowers July-October.
