seed collected in my own garden. It has now flowered for five 
years. It begins to flower early in July, and continues in flower 
till hard frost. It has never produced fertile seed. The other 
hybrid was between A. Thomsoni and A. pyrenseus, DC. A. 
Thomsoni produces good seed very sparingly, but one plant 
growing between two plants of A. pyrenaeus produces good seed 
plentifully. Some of these seeds produce typical A. Thomsoni, 
and often the nondescript plant sent. This is entirely sterile. 
I have raised many, two or three years in succession. They 
always have a white pappus to the achene, which A. Thomsoni 
never has." 
Some Historic Cedars. — Rev. G. Henslow described two large 
Cedars (Cedrus Libani) in the garden of the Rectory at Bishops 
Waltham, which, since their age is known, are perhaps worth 
recording. They were planted to commemorate the Battle of 
Waterloo. Both have lost some large boughs. One, indeed 
(No. 1), has so greatly suffered in a storm that nearly half the 
tree has gone. This one must also have lost its leader at a com- 
paratively early date, as the main trunk now suddenly branches 
into five large erect minor trunks. It is 42 ft. in height. The 
other (No. 2) has retained its leader, and is about 50 ft. high. 
Three of its larger boughs have gone. 
No. 1. — The girth of the trunk at the parting of the roots is 
17 ft. The girth at a height of 5 ft. from the ground and just 
below the lowest bough is 15 ft. The girth of the lowest 
bough is 6 ft. This bough arises at a height of 5 ft. from the 
ground. 
No. 2. — The girth of the trunk at the parting of the roots is 
17 ft. The girth of the trunk at a height of 5 ft. from the 
ground is 14 ft. The girth of the base of the lowest bough is 
5 ft. 2 in. This bough arises at a height of 1 ft. 3 in. from the 
ground. A bough at a height of 4 ft. 4 in. from the ground 
has been sawn off, revealing fifty-seven rings of growth. In all 
the boughs removed the eccentricity is remarkable ; in one 
instance the centre is 4 in. from the upper surface, and 15 in. 
from the lower. The situation is high and the soil clay. Both 
trees are bearing cones. 
Pear diseased. — Mr. Veitch of Exeter forwarded a Pear 
attacked by a fungus, which had assumed a remarkable spiral 
growth round the fruit.
