11. Very sparingly in a marshy piece of ground near St. Johns. In 



a swamp in a wood between Hatt and Kingsmill ; several plants, 



but weak from the shaded situation, 1870. 



D. III. Plentiful in some swampy spots, surrounded by coppice, in War- 



leigh Wood, Tamerton Foliot. 



IV. In the vale below Rock Brake, and about the source of a small 



tributary of the Plyni m Turtles Wood, and in considerable 



quantity in damp spots at Common Wood ; all on the right 



bank of the Plym, in the parish of Egg Buckland. Sparingly 



in certain damp spots about streams on Coleridge, Derriford, 



and Fursdon estates. Egg Buckland. 



V. A single plant by the turnpike road near Lee Mill Bridge, August, 



1866. Sparingly scattered about the sides of the tributary of 



the Yealm on the flats below CholwichtoAvn. 



VI. Ivybridge, in a bog, and on a bank very near the railway station. 



First recorded as a Pl^yniouth species, and also as a British one, in the 



Journal of Botamj for February, 1864 (vol. ii. 45, 46), and in a part of 



English Botany, ed. 3, published about the same time. The figure of 



the plant m both works was drawn from dried specimens collected in this 



neighbourhood and forwarded by me. Unfortunately, however, neither of 



the plates gives a really good representation of this beautiful H}TDericum. 



Besides my notice of it in Journal of Botany just referred to, a valuable 



one by Professor Babington will be found at p. 97 of the same volume. In 



subsequent volumes I recorded some of its local stations. When a young 



botanist I mistook it for duhium, and it appears under this name m a 



" List of Uncommon Plymouth Plants," contributed to the Phytologist in 



1861 (vol. V. N. S., 369). It comes into flower about the third week m 



July, a fortnight after tetrapteram. Its flowers are of a much brighter 



yellow than those of that plant. The two are sometimes found together. 



Both are subject to the attacks of the larva of a small insect, of the 



name of which I am ignorant, that frequently eats away so much of the 



foliage as to prevent the plants from producing flowers. The stations at 



Ivybridge are the most eastwardly known in Britam for H. hoeticuin, but 



to the Avest of our Plymouth area it becomes more general, and in the 



extreme south-Avest of CornAvall is an abundant plant ; which renders the 



fact of its having been so long either overlooked or confused A\ith other 



species the more remarkable. At Derriford, Egg Buckland, it ascends 



to 300 feet. 



127. H. humifusum, L. Trailing St. John^s Wort. 



Native ; on dry or stony banks, and on commons. Very common. 



June to September.
