46 HYPERICUM UNDULATUM. 
side, slightly dotted with black on the edges. Styles about as long as 
the ovary in the fully expanded flowers, half as long as the capsules. 
“Differs from H. perforatum by its quadrangular. stem, broader 
leaves with network of pellucid veins, broader and blunter sepals, and 
styles only half as long as capsule; from H. dubium by its closely dotted 
leaves and erect sepals ; from H. quadrangulum by its less robust and 
less decidedly winged stem; more dotted leaves, larger petals, and diffe- 
rently shaped sepals ; from all three by the much fewer and more dis- 
tantly placed flowers of its panicle.” 
lected the plant on the 7th of August, 1861; it grows 
plentifully by a stream (a small tributary of the Plym, on the right 
bank), and in boggy ground at Common Wood, about four or five. 
miles from Plymouth, Devon; and occurs less abundantly by a stream 
in a meadow at Fursdon, Egg Buckland, about a mile: from Common 
Wood, and in the same county. I noticed the following plants grow- 
ing with it:—Hypericum Elodes, Epilobium palustre, Hydrocotyle vul- 
garis, Wahlenbergia hederacea, Sibthorpia Europea, Anagallis tenella, 
Juncus acutiflorus, Narthecium ossifragum, and Osmunda regalis. 
I have since been informed, by Professor Babington, that this Hype- 
ricum is a species widely distributed over Southern Europe, Northern 
Madeira, and the Azores, the M. undulatum, Schousb., H: deci- 
piens, Watson, H. Neapolitanum, Tenore, and probably also the H. 
Baticum, Boiss. Elench. 40 ; Voyage, n. 332, t. 84,—H. undulatum 
being the oldest name. M. Boissier gives the following diagnosis of 
H. Beticum :—* Caule erecto, 2-3-pedali, quadrangulo, angulis sub- 
alatis; foliis ovali-lanceolatis, obtusis, subamplexicaulibus, subtus evi- 
denter 5—6-nerviis, glabris, densissime pellucido-punctatis, margine 
nigro-punctatis, panieula elongata, laxa, bracteis linearibus, sepalis 
ovato-lanceolatis acutis obtuse crenatis, margine ni unctatis, cap- 
sula matura subduplo brevioribus ; petalis et antheris nigro-punotatis."' 
I should add that Dr. Seemann has just received a letter from Pro- 
fessor Alexander Braun, embodying the result of a comparison of one 
of my specimens with those of M: undulatum, in the Berlin herbarium: 
An abstract of this letter, together with a coloured plate, and critical 
remarks on the synonyms and geographical distribution of the plant, 
will be found in an article by Professor Babington, now nouus for 
one of the forthcoming numbers of the * Journal of Botany."
