3.—MA11TYNIA DIANDRA, Gloat. THE D1ANDROUS MARTYNIA. 
Synonymes.— M. angulosa, Lam. ; M. rcliq Houst. Specific Character. —Stem branched; leaves opposite, lobed, 
Engravings. —Bot. Reg. t. 2001 ; Bot. Rep. t. 575 ; and our Jig. cordate at the base ; stamens 4, two of them sterile.—(G. Don.) 
2, in Plate 40. 
Description, &c.— The spike of flowers of this species grows differently to that of all other kinds ; and 
instead of being terminal, it always springs from a fork between the stem and branches. The flowers are very 
curiously marked. The leaves and calyxes are of a pale green, and the latter have a sort of involucre formed of 
two delicate membranous bracteas of a beautiful pale pink. The whole plant has rather an unpleasant smell. 
It is a native of Yera Cruz, Mexico, and was introduced in 1731. It is rather more tender than the other 
species, but in favourable situations it grows above two feet high, while the others rarely exceed a foot or eighteen 
inches. It should be grown in rich light soil, in a warm border in front of a south wall. 
M. LONGIFLORA, Lin.; M. CAPENSIS, Glox. 
The flowers of this species are very long, and purple. It is a native of the Cape of Good Hope, and was 
introduced in 1781, but has long been lost to our gardens.

Description, &c. —Collinsia verna was the first species of the genus discovered, and it was found by Nuttall 
in the spring of 1810, growing in the alluvial soil on the borders of Lake Erie. He unfortunately lost the 
specimens he gathered, but the plant was found about the same period on the banks of the Missouri and 
Mississippi rivers by Mr. John Bradbury. In the spring of 1816, Nuttall undertook another journey in search 
of this plant ; and after seeking for it in vain, during a journey of more than a hundred miles, he at last
