which it thrives in a Eoxburgh station is indicated in one of 

 the illustrations (Plate X.) Mr W. B. Boyd of Faldonside, 

 who first discovered it there, inclines to the idea that it was 

 introduced to the locality with the trees. The latter are 

 about a hundred years of age, and came from the north of 

 Scotland. In England, Linnsea is found, according to Bentham, 

 in a single locality in Northumberland. In Europe it is 

 widely spread. In Scotland the principal flowering months for 

 Linnsea borealis are during June and July. The flowers are 

 very fragrant, especially at night, and the perfume is perceived 

 some distance from the forest. The English name for Linnsea 

 is " twin flower." Occasionally three flowers occur on a scape. 

 I have not noticed in this country the rare white-flowered form 

 sometimes met with on the Continent. It is normally pink, 

 with red colouring within the corolla, which is intermediate 

 between bell- and funnel-shaped. 



For Goodyera repens, "according to ' English Botany/ the 

 most southerly station is at Dalmeny. But a hundred paces 

 or so from the Linnaea carpets in Eoxburgh mentioned previ- 

 ously there is a fair quantity of Goodyera, which appears to 

 be gaining ground beneath the pines. It flowers during July, 

 and perhaps is nowhere so plentiful in Scotland as in a wood 

 near Troon, where its whitish flowers are quite a feature. 



Trientalis europaea, the Chickweed Wintergreen, varies much 

 in size, and also in the number of segments into which the 

 calyx and corolla are divided — from five to nine. The stamens 

 are equally variable in number, while the leaves, which 

 approach a whorled arrangement, usually agree in number with 

 the petals. The flowers of Trientalis europaea are usually 

 white, but occasionally pink. The tube of the corolla is very 

 short, and this gives the flowers a starry appearance, unlike 

 many of the Primulaceae. Although its name might suggest 

 but little variation from its normal size, few plants range so 

 greatly in stature. Specimens from Lapland and the neigh- 

 bourhood of the Behring Straits have leaves not two inches in 

 length, and stems from two to three inches in height, the 

 flowers remaining, however, of the usual size. Contrasted 

 with such are those found in more favourable regions, some 

 with stems over twelve inches in length. The floor of those 

 Scottish woods in which the plant abounds is prominently
