OF A CAMBRIDGESHIRE WOODLAND. 351 
Saliw cinerea, the Grey Sallow, occurs in some of the wet parts but is 
nowhere abundant. Salie Caprea, Sallow, also occurs but is rare. 
Crateequs, Hawthorn, occurs scattered through the wood— both C. monoyyna 
and C. огуасат а occur here, the former being more common. 
Prunus spinosa, Blackthorn, and P. insititia, both occur but chiefly at the 
edge, where in parts they form a hedge. P. spinosa var. macrocarpa occurs 
sparingly. 
P. Cerasus, Cherry, is rare but does occur. It is another plant inentioned 
by West * as probably extinct. 
Other shrubs are Cornus sanguinea, Dogwood, and Huonymus europea, 
Spindle-tree, both of which occur in considerable quantity as under-shrubs. 
Pyrus Malus, Apple, oceurs in small quantity as a shrub. 
Viburnum Lantana, Wayfaring Tree, Г. Opulus, Guelder Rose, and 
Ligustrum vulgare, Privet, are locally abundant, especially the last named, 
Sambucus nigra, Elder, is rare. Kubus spp. (especially Г. cersius) and Kosa 
spp. (especially В. arvensis) occur in considerable quantity locally ; they will 
be considered along with the ground flora. 
Rubus Ideus. A few bushes occur in the wood. White Wood, Gamlingay, 
on Greensand, was previously the only record of this plant in West 
Cambridgeshire f. It has recently been noticed in another Ash-Oak wood in 
S.E. Cambridgeshire, on the Boulder Clay. 
А “pseudo-shrub” growth of Ulmus and to a less extent of Populus 
tremula is produced in parts after the cutting of the shrub layer by extensive 
suckering. 
The principal shrubs—//azel and Ash—appear to be in a quite natural 
condition, except for the periodic cutting. There is no direct evidence of the 
planting of shrubs or trees, and none occur that can be considered as alien to 
the habitat. The distances between the shrubs show no more regularity than 
would be expected in such a dense growth. On the other hand, in one or two 
small isolated areas in the wood the Ash and Hazel shrubs are arranged in 
roughly alternating rows, with sufficient regularity in the limited area to 
suggest the work of man. Over much the greater part of the wood there is 
no evidence of this sort. Assuming that at some time Hazel and Ash have 
been planted, they would seem to have been put in to replace others of the 
same species. 
Climbers ате not abundant. Lonicera Periclymenum is the most so, 
especially on the loam, though not confined to that part. 
Hedera Ней occurs near Ње edges, climbing some of the trees, but does 
not creep over the ground. 
Other climbers are Tamus communis and Bryonia dioica ; the last named 
is confined to the edges. Both are confined to the clay.
