These characters are taken from Ruiz and Pavon's specimens in Mr. Lambert's Herbarium. 

 The Horticultural Society's collections contain a Chilian plant which bears considerable re- 

 semblance to the other Gardoquias, but appears to have the style regularly bifid. The specimens 

 are not, however, good enough to enable me to determine exactly its affinities.

These four last genera are separated only by distinctions so vague and so slight, that they 

 ought perhaps to form but one, which woiild be well characterised by the 13-nerved tubular 

 calyx (it being constantly 15-nerved in Nepeta and Dracocephalum, and ovate or campanulate in 

 Melissa, Lepechinia, and Thymbra), and especially by the conformation of the style, which is 

 nearly the same as in Sideritis.

The structure of the style in this genus seems to shew that that of the Labiatae in general 

 should be considered as consisting of the union of four distinct styles, and each lobe of the 

 ovarium as one of four distinct ovaria connected together. In some specimens of Prunella I have 

 observed a third, and even a fourth, tube in the style, reaching part of the way up the divisions 

 of the apex, and there terminating in a very small stigma.
