winged, sparingly and shortly branched upwards ; 1. decussate 
oblong or elliptic-oval thickly and minutely pellucid-dotted, 
the margins beneath black-dotted in a row near the edge ; 
cyme large leafy open or spreading; sep. erect equal narrow- 
lanceolate very acuminate quite entire black-dotted ; pet. lan- 
ceolate sparingly black-dotted, anth. copiously so ; styles diver- 
gent shorter than the stam. not much longer than the ovary. —

H. quadr angular e Brot. ii. 322. H. tetraptenim (Fr.) Koch 147. 
— Herb. per. Mad. reg. 2, 3 ; c. Mountain-dells and steep banks 
in moist or shady spots here and there ; general but not abundant. 
Rib. Frio, R. da Metade, R. de Machico, &c. In the North in 
ravines above Santa Anna ; cliffs above the Passa d’Area by the 
road, &c. July-Oct. — Rather light gr. St. 1-2 ft. high with short 
remote leafy opposite side-branches. L. 6-9 lines long, 3-4 lines 
broad, rather small but larger than in II. perforatum L. often 
thinly and obscurely sprinkled beneath -with a few black dots 
besides the marginal row ; the lower obtuse, upper acute. FI. 
rather pale or lemon-y., reddish in the bud. — This sp. is not 
included in Von Buch’s Madeiran List. Solander in his MS. 
List of Madeiran pi. has an “ H. ovatum Masson : Hab. in de- 
clivibus rupium but no H. quadrangulum. And in the 
Banks. Herb, no Madeiran specimen exists of either pi. It can 
only therefore be surmised that possibly by H. ovatum , H. qua- 
drangulum L. might be intended and the name afterwards sup- 
pressed by Solander on discovering its identity with the Linnsean 
sp. ; for he has left no record of the char, of his H. ovatum . — ■ 
The Azorian H. decipiens Wats, by a specimen in HH. from 
11 S. Michael, 1846,” appears not to differ essentially from the 
present sp.
