(PLATER XVI.) 
At page 45 of the present. volume there is a notice of the discovery 
of this Hypericum near Plymouth, and to fulfil the promise then given, 
these remarks and the aecompanying Plate are issued. 
The following seem to be the specific character and synonymy of the 
plant :— 
H. undulatum (Schousb.) ; stem erect, branched, 4-edged, herbace- 
ous ; leaves oblong, wavy at the edge, with many pellucid dots, netted 
with pellucid veins, and (as well as the sepals and petals) with black 
marginal dots beneath; sepals erect, ovate-lanceolate, acute, usually 
very bluntly erenate ; petals persistent ; stamens shortly united in three 
sets; styles 3, not half as long as the capsule. -

Stem 9-3 feet high. Leaves declining, more or less conspicuously 
wavy at the edge, abundantly uniformly and pellucidly dotted through- 
out. Flowers in very lax, much branched cymes. Petals yellow, with 
a longitudinal dash of red externally on their sinistral side, and black ^ 
dots on their dextral side... Anthers with a black dot. . Styles 3, diva-

"^'fmhe localities in Devonshire are carefully described by Mr. Briggs, 
"he fortunate discoverer of them, at p. 46 of this volume. 
The annexed interesting letter, from Dr. A. Braun, proves that our 
plant is the H. undulatum. Welwitsch’s specimen (no. 171) is much 
stronger than the English plant, the leaves are much more markedly wavy
