bark of tree^ with <*onspicuo\isly rich yellow and orange or 

 reddish variegated lustre, in lengthened continuous or shorter 

 broken patches. V/^hen examined with a microscope it ap- 

 pears rising in the cracks or hollows in elongated capsules or 

 spherules, sometimes emitting a thick mucilaginous liquid 

 more copious than the capsule, and sometimes it is contracted 

 to dryish cups, as if it had had a seed or powder. The mag- 

 nified section shows this.

PUCCINIA Buxi. 



UOX-HILL, so famous for the Buxus sempervirens, E. E. 

 i34I, produced this parasite rather plentifully. It forms under 

 the skin of the leaf like most Aecidiums. It has, however, only 

 a rugged broken border, and not any regular notches or ser- 

 ratures. The seed, when highly magnified, appears to be 

 included in numerous stiped double capsules about lOOOth of 

 an inch in diameter, and of an ocliraceous brown,

GHANULARIA yiolm. 



jVIy son, J. D. C. Sowerby, who brought the last specimen 

 from Box-hill, brought me this from Dorking on the 11th of 

 August, 1814. It was the apparent cause of a very swollen 

 peduncle (three or four diameters bigger than usual) to the 

 lea^ves, now and then forming in little black looking spots 

 outside and within, which on examination with a magnifier 

 only exposed little clusters of minute spherulate granulac, 

 those in the centre brown, and those on the sides lighter. 

 These or other small parasites belong more or less to all 

 known plants.

1 SOMEHOW forgot to mention these three rings of colour. 

 In the description of that plate I noticed the commencement 

 of Fungus matter, and meant to show that colour in wood 

 sometimes preceded it; yellow perhaps oftenest, gray or 

 bluish next, and crimson, sometimes alone and in succession; 

 and that the beginning of decay in various subjects might be 

 thus indicated. I have, however, met with those who have 

 considered the first and last as indications of soundness in 

 wood, at the same time as it has bee» the cause of extensive 

 mischief and expensive loss.
