A very common inhabitant of the same parts of India as 
h. trigyna, figured in this work as Linum trigynum (see 
Plate 1100), and so closely allied to it, that it is doubtful 
whether intermediates may not prove them to be varieties © 
of one. In the form here figured it is a very different- 
looking plant, with longer acuminate serrated leaves of a 
lighter colour, and paler yellow larger flowers than those 
of the form of L. trigynum now in cultivation, though a 
reference to the plate of this work cited above shows that 
as then cultivated the flowers of 2. trigyna were quite as 
large. The character upon which the two species were 
both founded and named, that of three and four styles, is 
a very fallible one, for the styles of 2. tetragyna vary from 
three to five. , : 
A more interesting point in the history of the Rein- 
wardtias is that of their trimorphie flowers as regards the 
relative lengths of their stamens and styles. That these 
organs were di- and trimorphic in various species of Linum 
proper was first indicated by Mr. Darwin, in papers com- 
municated to the Journal of the Linnean Society of London 
(vol. vi. p. 96, and vol. vii. p- 69), wherein the effects of their 
relative positions in respect of the fertilization by insects of 
the flowers and the amount of seeds produced, is worked
