Abundant on the Sidlaw Hills, and not unfrequent on the 
higher mountains. Bare in ft. In April 1840 I picked 40 
fruited specimens on the margin of a small marsh on the 
north-west side of the White Hill of Auchterhouse ; and Mr 
Croall has met with it in that state in Guthrie Woods, half 
a mile west from the Brechin road.

This interesting little plant, esteemed alike for its rarity 
and curious structure, I had the pleasure of detecting on the 
White Hill of Auchterhouse, one of the Sidlaws, in May 
1840, and have gathered it fifteen times since. The White 
Hill derives its name from the encrustation of its rocky front 
with various white lichens, as Variolaria lac tea, Isidium 
paradoxum, &c. It rises with a peaked-like summit behind 
the village of Auchterhouse to the height of 1400 feet above 
the sea-level. On its northern slope there is a secondary 
hill, and here the plant was first found sparingly scattered 
in small bare hollows among the heath, where the snow had 
lain longest in the spring. In these spots its associates were 
small Polytricha and Scyphophori , which rendered its de- 
tection more difficult. In June, the same year, two more 
specimens were obtained, and several in April 1841. In 
May 1841 seventy-two specimens were picked, and forty- 
three in May 1842. In May 1843 sixteen specimens were 
met with in the old ground ; and in April a single plant 
under the shade of heath at the south-west corner of Deer- 
hili Wood, nearly three miles distant. In 1844 ten speci- 
mens were gathered in March, forty in April, and fifty in 
May. One was procured in March, and twenty in May, 
1845. In 1846 seven were picked in February, and three
