This in my opinion is one of the most charming species of the whole genus. It grows to be a large ramoiis plant, 

 which at first sight may be easily recognised on account of the four waved wings of the stem and principal branches, 

 which are very broad in the middle, between the joints, but gradually decrease and almost entirely disappear towards 

 the joints themselves. The leaves are very unequally petioled, one of the petioles in each pair being always considerably 

 shorter than the other, so that towards the upper ends of the branches one of the leaves becomes sessile, while the 

 other is petioled. The flowers are large and exquisitely beautiful, of a purple colour, pale or nearly white without.
