BOTANY OF THE AZORES. 589 
less crowded flowers ; and if the tetrapterous stem 
were not observed, it would more likely be called 
H. perforatum by a British botanist. Still, if it. 
be correct to include H. dubium and maculatum 
under H. qguadrangulum, this also may be added 
to the assemblage. Dr. Lemann suggested the 
variety “ undulatum” of DC. Prodr. 2.548 ; but 
the only character of that variety “foliis mar- 
gine undulatis" applies to some specimens of 
H. dubium and of the ordinary H. quadrangulum 
of Britain. Probably this is the same as H. per- 
Jforatum of the Flora Azorica, which is stated to 
occur, * ubique in lapidosis collinis," yet was 
not found by me. My flowering specimens of 
H. decipiens were collected on damp rocks, ex- 
posed to the sun, in Flores ; and I possess what 
is apparently the same species, though destitute 
of flowers, collected in Fayal. It has been sent 
to the Botanical Society of London, from San 
Miguel, by J. C. Hunt, Esq., British Consul 
there. In my garden, even in dry ground, it is 
a much finer plant than the British H. quadran- 
gulum, which grows in wet ground. __
