Tropics in Mexico. Mowers of JLexacentris coccinea and Salvia 
clegans were also shown. 
Diseased, Yew .—Dr. M. T. Masters, oh the part of the Hon. and 
Ilev. J. T. Boscawen, submitted a twig of Yew of which some of 
the leaves were affected with a Fungus. Dr. Cook described it 
as a species of Sphcerella , giving them quite an ornamental ap¬ 
pearance. 
Lycoperdon giganteum. —Dr. Masters exhibited, on the part of 
Miss Ormerod, specimens of this Fungus, with the following 
letter:— 
11 Miss E. Ormerod begs to forward two unusually large speci¬ 
mens of Lycoperdon giganteum , Smith, found yesterday beneath 
the floor in Spring Grove Church. The spot was apparently in 
good order, and the specimens are said to have been growing only 
on ‘ dry rubbish,’ but they are of such large size they may possibly 
be of interest. The largest of the two, much resembling a mass of 
half-baked dough fallen into a flattened oval form from its own 
weight, is 3 feet 5 inches in circumference, 3 feet 3 inches longest 
vertical ditto, 3 feet shortest ditto; 10 inches in height.” 
Revolving Movement in the Leading Shoot of Abies JYordman- 
niana. —Dr. Masters showed a diagram indicating the revolution of 
the leading shoot of this plant as observed in July last during the 
period of growth from hour to hour during twelve hours. The 
shoot made a swoop round, keeping its point to the east from 9 a.m. 
till 3 p.in., from which time till 7 p.m. it was directed vertically 
at 8 p.m. the tip of the shoot pointed to the north, and at 9 p.m. 
to the north-west. 
Growth of Flower-stem of Tritoma .«—Dr. Masters showed a 
diagram representing the rate and direction of growth in the flower- 
stem of this plant. "When originally measured the total length 
from the groundTo the base of the inflorescence was 5 J inches. This 
space was marked out with compass points into spaces one-eighth 
of an inch apart, there being forty-two in all. "When growth in 
length had apparently ceased for some days the intervals between 
the marks were measured, and showed extraordinary variations. 
In some cases little or no growth had taken place, the marks re¬ 
maining one-eighth of an inch apart; in others great growth had 
taken place, in one case to as much as 1§ inch. On the whole, 
the greatest growth was in the upper one-third of the stem. The 
mean growth of the entire number of species was between five- 
eighths and six-eighths of an inch.
