ANALYTICAL DRAWINGS OF THE CRANE’S-BILL ORDER— continued. 
Fig. 6, the same dehiscing, the carpellary valves having coiled up inwards, dropping 
seeds ; and Fig. 7, one of the seeds. 
The sixth line begins with the analysis of the Narrow-leaved Flax ( Linum 
angustifolium Hudson), Fig. 1 representing a flower as seen from above, of the natural 
size ; Fig. 2, the same in section ; Fig. 3, the essential organs ; Fig. 4, a young 
fruit with the calyx ; Fig. 5, a cross section of the fruit, enlarged, showing the 
ten apparent chambers, each containing a seed ; and Fig. 6, a ripe fruit dehiscing 
into valves. 
Fig. 7 in this line shows two plants of the minute Flax-seed or All-seed ( Radiola 
linoides Roth), the sole representative of its genus, frequent on damp heaths, where, 
numerous plants often growing side by side, it is not easily overlooked, although 
never more than four inches high. It is an annual, with repeatedly-forked, thread- 
like stems, forming a typical dichasial cyme. The slender stems, the opposite pairs of 
minute, ovate-acute leaves, and the fugacious white petals all recall Linum catharticum 
Linn£ ; but in this plant the floral whorls are all in fours and the sepals are deeply 
three-cleft. The numerous little round capsules, terminating its many branches and 
closely resembling the “bolls” or fruits of the Flaxes, have given it the names of 
All-seed or Flax-seed; but the scientific name Radiola, a diminutive from the Latin 
radius, a ray, has been variously explained as taken from the valves of the dehiscent 
capsule, resembling the spokes of a wheel, or from the many widely divergent 
branches of its stem. The specific name linoides merely means “resembling Flax.” 
Internally its capsules closely reproduce the structure of those of Linum, but with 
four carpels instead of five, and accordingly eight apparent chambers and eight seeds. 
The last line on the Plate represents the Milkwort ( Polygala vulgaris Linne), 
Fig. 1 being a flower seen sideways ; and Fig. 2, one seen from above, both natural 
size. Fig. 3 is a flower seen from below, enlarged ; Fig. 4, a longitudinal section ; 
Fig. 5, the gynaeceum ; and Fig. 6, the andrcecium, all somewhat enlarged. Fig. 7 
is a young capsule with the calyx, and Fig. 8, a section of the same ; whilst Fig. 9 is 
an enlarged view of Fig. 8. No attempt has been made here to emphasise the 
veining of the “ wing ” sepals, which forms one of the most important distinctions 
between our closely allied British species. In Poly gala vulgaris Lin 116 they have 
an almost unbranched central vein prolonged into the point of the sepal, whilst 
the two lateral veins branch freely, their branches re-uniting and looping on to 
the central one.
