1859.] NOTES ON THE BELGIAN FLORA. 163 



Its head of pale-purple flowers might, on a cursory glance, 

 be mistaken for Jasione montana, but the plant is very 

 different in appearance, besides that it blooms much earlier. 



Helleborus foetidus. Abundant on the limestone everywhere. 



Helianthemum polifolmm. Rocks along the Mouse, between 

 Dinant and Yvoir. 



Impatiens Noli-me-tmigere. Abundant along the swampy banks 

 of the Bocq, a stream already named, which falls into the 

 Meuse at the village of Yvoir. 



"^Lactuca perennis. Limestone rocks, and ruins of Poil-vache, 

 etc. 



Libanotis montana. [Athainanta Libanotis, L. — Seseli Lib., L. 

 Cat.). Very common on the rocks everywhere round Dinant. 



^Luna7-ia rediviva. Valley of the Bocq, on the rocks. 



QLiiothera biennis. Same locality. 



Orchis Tephrosanthos, Vill. I have found several specimens, 

 but never two succeeding years, nor twice on the same 

 spot, though I invariably left the tubers in the ground, in 

 the hope of seeing them spring up again. Did I destroy 

 them by plucking the flowers ? 



*Orlaya grandiflora. Rather local, but flourishing abundantly 

 where it does grow. Some cornfields near us are remark- 

 ably gay every summer with its numerous large, pure- 

 white umbels mingling with the bright red and yellow 

 Melampyrum arvense. 



Phyteuma spicata. Common in woods almost everywhere in 

 Belgium. — P. orbiculare is rare. I have not yet met 

 with it. 



^Polygala comosa. A species recognized by Continental bota- 

 nists, but not named in our English Floras ; was common 

 here on dry waste ground till within the last two years. 

 It seems, like Crassula rubens, to have been checked by the 

 late hot, dry summers. 



Stachys germanica. Common on the limestone. 



Teucrium Botrys. Waste places on the slopes of hills; abundant. 



Teucrium Chamcedrys. Crevices of the limestone rocks ; equally 

 common. 



To this list may be added the Gooseberry, Currant, red and 

 blackj and the Raspberry, which we find in localities where
