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 Jrd 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
