TETRANDRIA. TETRAGYNIA. 
THALAMIFLORA. LINACE2. 
RADIOLA. (FLAx-sEED.) 
Generic Character. Calyx of four leaves united up to the 
middle, and mostly three-cleft. Petals four. 
RADIOLA MILLEGRANA. (Plate XVI. Fig. 61.) TZhyme- 
leaved Flax-seed. A most curious little plant, so minute 
that it is only likely to be observed by a botanist. It is 
scarcely more than an inch high, so that the whole plant 
lies in a very small compass. Its leaves are distant, entire, 
smooth, and, under a high magnifier, appear dotted. The 
minute flowers are on the top of the branches, single, and 
on short stalks. ‘The slender stem is repeatedly divided into 
two parts, or forked, as it is termed. It must be sought 
for on boggy soils and in the wet parts of heaths.
