BOTANY OF WYRE FOREST. 359 
the other, Thymus Serpyllum, very little taste or smell; this led 
me to a more close examination of these several characters, first 
by sowing the seed of each species, which followed their parents 
truly, then year after year I closely examined their habits and 
stratal adaptations. Thymus Serpyllum thrives better on very 
dry, sandy rocks, or dry ditch-banks, comes into flower in June, 
out of bloom in August; sheep, I observe, eat it readily. Thy- 
mus Chamedrys comes into flower in July, generally a month 
later than the other, thrives on cold, clayey soils, often remains 
in flower until November; sheep will not eat it, owing to its 
pungency. 
Trifolium medium, Sinapis nigra, abundant on the banks of 
the River Severn; Trifolium striatum, Senecio erucifolius, Tees- 
dala nudicaulis, Tulipa sylvestris, Turritis glabra, Typha angus- 
tifolia, Verbascum Lychnitis, Verbena officinalis, Veronica mon- 
tana, Verbascum nigrum, Veronica scutellata, Vinca major, V. 
minor, Viola hirta, V. canina, V. sylvatica, V. odorata, var. im- 
berbis: this will ultimately be considered a distinct species of 
Violet; from seed I find it strictly to maintain its distinct cha- 
racter, destitute of the hairy line; it is very abundant here; less 
so is the blue, or V. odorata; I have examined them from every 
locality in this part of the country, and find this character very 
constant. 
Taxus baccata, plentifilly disposed in woods, hedges, and ra- 
vines. The Yew varies much in its contour ;*in some the 
branches spread much alike to the Cedar ; others with an ovate 
outline. A few are found with pensile branches; this form is 
very beautiful indeed, particularly when adorned with their scar- 
let drupes. I have frequently planted the seeds of the Yew from 
a tree distant more than a mile from the male tree; they all 
vegetated from the second year after planting. 
Viscum album: this parasite is found sparingly on the Ash, 
White Willow, Pear, Lime, Black Poplar, Red Maple, Great 
Maple; very abundant on the Apple, Crab, Hawthorn; very 
abundant and luxuriant on a Poplar lately introduced into this 
country, by some called the Carolina Black Poplar, by others 
Italian Black Poplar; on this tree it grows in a short time to a 
much larger size than it does on any other tree, probably from 
the rapid growth of its new foster-parent. 
I have some reason to believe that this parasite springs spon-
