The description of this plant given by Sir J. E. Smith in his English Flora 
is so good as not to require any addition, except in that part which refers to 
the flower, to which I would add the following : 
Upper lateral petals about $rd longer than the anther, obtuse; spur about 
twice as long as the germen, thickened towards the end; anther very 
large, truncate, the bases of the cells being twice as far apart as their 
tops, giving to the whole anther a somewhat semicircular character, the 
central line between the cells in front elevated into a prominent keel 
and forming a furrow on the back; stigma very broad at its top and 
slightly pointed in the middle, curved into a semicircular form. Flower
