DIDYNAMIA ANGIOSPERMIA. 137 



Calyx striped with green and reddish-brown ; the segments 

 setaceous, rough, shorter than the tube. Upper lip of the 

 corolla villose internally ; lower lip straight, in 3 acute 

 short segments, slightly projecting ; the palate raised, 

 orange. Anthers green and brown, pubescent, on smooth 

 filaments. The flower is generally unspotted, but some- 

 times there are 4 small obscure spots on the lower lip, 

 placed distantly, and not on the mouth. 

 It is not without hesitation that I give this as a species dis- 

 tinct from the preceding, since the differences may be 

 attributed to situation, for we know that an alpine station 

 does alter the aspect of plants to a considerable extent. 

 In estimating the force of this objection, we can only rea- 

 son from what we observe to be the effect of a similar si- 

 tuation on plants of the same natural order. Now, the 

 Rhinanthus Crista-Galli is a plant of this kind, and we find 

 it growing with this Melampyrwn undiminished in height, 

 and unaltered in appearance. And, were the objection 

 valid, we might expect the plant at the base of the hill to 

 be much in its usual state, and gradually diverging from 

 it as it attained higher limits ; but this was not the case, 

 for it was very uniform in character over a surface of 

 many acres.
