exterior; the corolla-tube is rather longer than that of 
P. integrifolia, and is funnel-shaped rather than ventricose. 
It agrees with the description of P. violacea var. “ Gloire 
de Segrez’”’ in Vilmorin-Andrieux, Les Fleurs de Pleine 
Terre, ed. 3, p. 848, which was raised from a garden 
Petunia known as “ Marquis de la Ferté.”’ It is said to 
reproduce itself exactly by seed, and is believed to be 
the same as P. violacea oculata, Hort., and P. ‘‘ Countess 
of Eliesmere.”” In 1911 an effort was made by Kew to 
secure the re-introduction of the true P. integrifolia from 
South America, and a request for seeds was sent to 
Sir Reginald Tower, His Majesty’s Minister at Buenos 
Aires, who had on many previous occasions given 
invaluable help to the establishment. The trouble he gave 
himself in consequence of this request seemed endless, 
and amongst others whom he interested in the search for 
the plant should especially be mentioned Mr. Carlos 
Thays, at that time Director-General of Public Parks, 
Buenos Aires, and Mr. C. E. R. Rowland, Vice-Consul at 
Monte Video, since 1916 Vice-Consul in Mexico, where, 
we deeply regret to hear, he died in 1917. Mr. Rowland 
was at last successful in obtaining seeds of both P. integri- 
folia and. P. nyctaginiflora from a virgin district on the 
banks of one of the small tributaries of the River Plate 
in Uruguay, and these reached Kew in September, 
1916. <A plant of P. integrifolia raised from these seeds 
flowered in June, 1917, and provided the material for our 
figure. The species is now known from the Southern 
states of Brazil, from Paraguay, Uruguay and the 
Argentine Republic. It appears to vary considerably, 
and there js reason to believe from specimens in the 
Kew Herbarium that there are natural hybrids between 
it and P. nyctaginiflora. Dr. Fries has described as a 
subspecies, named depauperata, a form with smaller 
leaves, shorter peduncles and smaller flowers. His 
P. inflata must be very closely allied to P. integrifolia, 
and judging from the specimens at Kew, which, it should 
be stated, form but a small part of the material cited by 
Dr. Fries, it cannot be satisfactorily distinguished. It is 
characterised mainly by the peduncles remaining erect 
after flowering, while in P. integrifolia they are more or 
less deflexed. The cultivation of P. integrifolia presents
