Pestalozzia Guepini is not known to possess any other form of 
fruit or mode of reproduction than the condition described above. 
The disease under consideration is by no means new ; specimens 
of tea leaves attacked by the Pestalozzia, now in Kew 
Herbarium, are accompanied by the following note. “Tea leaves 
(blighted). Cachar. 1872 growth. A. H. Blechynden.” A 
second lot of tea leaves, suffering from the same disease, is 
accompanied by a note as follows. “Leaves from a tea tree 
recovering from ‘red spider.’ Sap just beginning to run through 
them. This tree like many thousands has not given any leaf for 
three months. T. B. Curtis. Receiv ed from Mr. Blechynden, 
Calcutta, by T. B. C., October, 1878. 
The fungus occurs as a parasite on leaves of plants belonging 
to the following genera :— Camellia, ESP Citrus, 
Magnolia, Alphitonia, N inobotus, did "Lager siromic 
Owing to its wide distribution at the present day, the original 
home of the HS ie is difficult to pienine with certainty, but 
the amount of evidence at hand suggests an Eastern nea In 
ages » -— on Camellia and pete bar S ; in Europe it is 
by ns uncommon, but always on introduced WO 
inlonding: to the two above-named genera. In the United States 
it occurs on introduced species of Camellia and UMP, from 
which it may possibly have passed on to the native Magnolia. On 
theother hand, it occurs on indigenous plants CNiphobolus) i in New 
Zealand, and on Alphitonia in Queens land. 
Preventive measuvres.—]1f the diseased leaves were collected with 
the amount of care and intelligence exercised in collecting sound 
leves, an burned at once after being collected, the disease would 
mped out, as the mycelium of the fungus is not 
— € in the tea plant ; consequenty infection, and. a recur- 
rence of the parasite, depends entirely on inoculation. by pe 
numerous conidia or eeu par [oed of the fungus present o 
diseased leaves. Remembering the very different kinds of Sioi 
on which the fungus is known to be parasitic, it is very probable 
i the 
tea gardens ; if such proves to be the case, all such plants should 
be removed if practicable, as the conidia 9 fungi are as con- 
Ey es Pampo by wind, birds, and insects, and no nt of 
attention in the of removing the parasite from the og panne 
would avail, if ika supply of conidia requisite for inoculating the 
tea plants were formed on other plants growing in the neigh- 
bourhood.
