 phyllus, L.). — The habitat of this plant is old walls, 

 hedges near gardens, old castle walls. The habil 

 is erect. The plant is smooth, bluish-green, stout, 

 much-branched, leafy below. The barren stems

 bracts are inversely ovate, blunt-pointed, J-J the 

 length of the calyx-tube. The calyx is cylindric, 

 obscurely ribbed, the teeth not fringed with hairs, 

 longer than the capsule. The petals are scal- 

 loped, toothed, inversely ovate, smooth, the teeth

Wild Pink (Dianthus plumarius, L.). — This 

 plant is semi-naturalized, or an escape on old 

 walls, and a frequent garden plant. The habit 

 is erect. The plant is tufted and branched. The

 ing. The leaves are linear, awl -like, acute, i- 

 nerved, with rough margins. The flowers are 

 fragrant, solitary, in loose cymes, rose or pale- 

 pink, or white, and the lobes of the fringed petals 

 are as long as the blade. The petals are much- 

 divided to the middle, digitate, downy, the central 

 part inversely ovate, entire. The calyx-lobes are 

 round to ovate, blunt-pointed, four times less than 

 the tube, fringed with hairs at the margin. The 

 capsule is longer than the calyx-teeth. The seeds 

 are flat, rounded, with a point one side. The 

 plant is 6-12 in. high, flowering in June and July, 

 and is a herbaceous perennial. 



English Catchfly (Silene ati^lica, L.). — This 

 plant is found in sandy places. The habit is erect.

 shaped. The flowers are pinkish-while, solitary, 

 axillary, alternate, small, in terminal racemes. 



The petals arc divided nearly to the base. The 

 plant is 6-24 in. high, flowering from July to Sep- 

 tember, and is a herb.iceous annual. 



Moss Campion or Cushion Pink {Silenc acau/is, 

 L. ). — The habitat of this plant is alpine rocks. 

 The plant has the cushion habit, and is densely 

 tufted, branched, bright -green, smooth. The 

 leaves are close, linear, awl -like, fringed with 

 hairs below, channelled above, keeled below. The

Spanish Campion (Siicne O/i/es, Wibel). — The 

 h.ibitat of this Campion is sandy and gravelly 

 places, fields and roadsides, heathy places, and 

 the plant is considered, with others, to be possibly 

 a member of a steppe flora. The habit is erect, or 

 the rosette habit. The stems are simple, sticky 

 at the base. This may exclude creeping insects 

 from the flowers. The roolslock is woody and
