The small corollas of the former resemble those of the large- 
flowered S. Verbenaca, but in my experience do not oc sae on the 
same plants as the proterandrous flowers. Another of a 
polymorphic corolla among the Labiate is apparently that of our 
common =the 58 ta Glechoma. 
In f these facts, then, and as M. Briquet’s emphatic 
obsarnitibas that all the different forms pass into one another 
seem to confirmed by a perusal of the specimens in the 
National Herbarium, where comparatively few are exactly alike, I 
am disposed to follow that author in referring the whole of these 
plants (except S. multifida) to one aggregate species, S. Verbenaca 
is, her ig | ee hair-clothing and the calyx as its most impor- 
peabalecian of this aggregate species I find a matter of 
some difficalt ty, which is enhanced by my limited acquaintance 
with the plants in a living state. The most natural ayaa 
as far as I can eee is that of the Abbé Coste, modified, in 
the way in which the different forms pass into each thie Med the 
reduction of his eres species to the rank of subspecies. This 
appears preferable to the ie apc roposed in Les Labiées 
des Alpes Maritimes, inasmuch as it seems correctly to make the 
type of S. Verbenaca an ititersiadinte between the S. clandestina 
cone: S. sited oe forms, and does not entirely ignore the floral 
charact 
lt sik ‘already been shown that the plant primarily intended 
in the second edition of the Species Plantarwm under the name of 
S. Verbenaca is a form of slender growth, with narrow, deeply-cut 
leaves. And it is unlikely that Linnzeus was actually acquainted 
wit the dark-coloured, ree robust t form that inhabits Great

ic. 167 (afterwards used by St. Am n his unt of S. pallidi- 
flora), which is obeinianty ¥ more like ¢ as * British plant than ic. 208, 
or the figure of Triumfetti. 
With regard to S. clandestina, the ot rg — in the 
Species Plantarum, together with Barrelier’s ic. 220, suffices to 
accurately fix it as the Siactoas ma in roms series with the most

The position of S. hormi von Pane: is not so clear, but as it 
is stated to be eealescent and intermediate between S. Verbenaca 
near the end of the series opposite to S. clandestina. It is note- 
worthy that in this instance a plant with cleistogamous flowers is
