[Preliminary Note by Siz J. D. Hooxer.—During a brief fur- 
lough in England, passed at Kew, Dr. Watt commenced a study 
of the Indian species of Primula and Androsace, which he 
intended, when completed, to lay before the Linnean Society. 
His recall to India prevented his completion of the task, and 
gave him the opportunity of collecting in the Sikkim Himalaya 
(which has proved to be the richest province of the Order hitherto 
known) new species and additional information and observations, 
which he at once transmitted to Kew. Meanwhile the advance 
of the * Flora of British India' having rendered it necessary that 
the description of the whole Order should be taken up for that 
work, Dr. Watt obligingly made over his materials to me with the 
request that I should deal with them as I thought best. Under 
these cireumstanees, finding that the value and interest of Dr. 
Watt's labours centred in the number of new and remarkable 
species which he had provisionally named and, for the most 
part, accompanied with more or less complete diagnoses, I have 
with his approval reexamined his material, revised his characters, 
and offer them in accordance with his intentions, and in his 
name, to the Linnean Society.—J. D. H.]
