Nearly all the Chinese Calaminthas belong to the group with 
long subulate calyx teeth, and the effort to find characters among 
them sufficiently constant to warrant specific differentiation has 
proved ineffectual, the writer being forced to the conclusion — 
that the numerous extreme forms which have at different times 
received specific names can only be treated as varieties connected 
by a series of intermediates. The chief forms occurring in China _ 
which have received specific names are :— 
(1) C. umbrosa, Benth. It is very common in the Talisch 
Mountains, where it was first distinguished as a species by 
Bieberstein (Melissa umbrosa, Bieb.). Thence its range extends - 
through Afghanistan and the Himalayas, to the Peninsula of 
India and Ceylon. (2) C. repens, Benth., from India. (3) C. 
chinensis, Benth., from China. (4) C. Clinopodium, Benth. 
(Clinopodium vulgare, Linn.), from the greater part of the N. 
Temperate Zone. 
Bentham at first placed these four species together as a 
section, Clinopodium, under Melissa, afterwards referring them 
to Calamintha. Hooker, in his Flora of British India, reduced 
them to two, C. Clinopodium and C. umbrosa, noting that they 
were in some states difficult to distinguish apart. The writer 
ventures to make a further step and place all under C. Clinopo- 
dium. ;
