Notes on Chinese Labiatae.

Kew. 
TuE following list comprises descriptions of new species, reduc- 
tions and transfers of old ones, and, in some cases, notes explana- 
tory of the views expressed. Exceptional opportunities have 
been afforded to the writer for the revision of the Labiatae of 
China by the bringing together at Kew of a splendid series of 
specimens from various herbaria of this and other countries. 
For these facilities his thanks are specially due to Sir David 
Prain, the Director of the Royal Botanic Gardens, Kew, who 
with great kindness has borrowed for him type specimens from 
Paris, Christiania, Berlin, St. Petersburg, and Florence, and who 
has allowed all the work to be done in the herbarium of Kew. 
Kew Herbarium itself possesses what is without doubt the 
most valuable and probably also the most extensive collection of 
Labiatae extant, containing as it does the specimens actually 
used and annotated by Bentham as the foundation for his classical 
Labtatarum Genera et Species (1832-1835). The specimens, more- 
over, on which Hemsley based. his exhaustive enumeration of 
Chinese Labiatae (1890), are in the Kew herbarium. The 
herbarium of the Natural History Museum was also consulted 
by the kind permission of the Keeper. 
The writer’s thanks are also very specially due to Professor 
Balfour, Regius Keeper of the Royal Botamic Garden, Edin- 
burgh, for entrusting to him the whole of the invaluable collec- 
tions of Chinese and Japanese Labiates in the Edinburgh Her- 
barium (some 864 sheets), and for sending them to him at Kew 
to compare with the material assembled there for the work. 
To Mgr. Léveillé the writer is much indebted for the courtesy 
with which he has lent him type specimens of the numerous 
newly-described plants from the province of Kweichow, a region 
very sparsely represented in other herbaria, besides that of the 
Société International de Géographie Botanique at Le Mans (France). 
The adjustment and, it is hoped, the simplification of the exist- 
ing nomenclature of Chinese Labiates, of which these notes indicate 
the chief points, has been undertaken to prepare the way for the 
preparation of keys sufficiently practical to enable botanists, 
and especially those collecting the living plants in China, to 
determine the names of their finds. The drawing up of these
