250 feet. 

 Cultivation at about 200 feet, Deel Bridge. 



Utricularia minor (Linn.) — About the Killary in several places, but 

 sparingly and much scarcer in the districts visited than U. inter- 

 media. 



There is little cultivation at the bases of most of the mountains 

 dealt with, and amongst the different ranges there are many extensive 

 glens and valleys whose botanical conditions are not influenced by the 

 hand of man. Several species are strictly confined to the bases of 

 these valleys, although apparently all the conditions requisite for 

 their growth are fulfilled higher up. Some are, perhaps, denied the 

 power of spreading, while, no doubt, a slightly decreasing mean tem- 

 perature as we ascend drives many competitors from the struggle, and 

 affords space for the hardier sorts to thrive and monopolize the soil. 

 It is of use to obtain a list of these species, which are thus, though ready 

 for the start, compelled to remain below. Plants of cultivation, or 

 affecting roadsides, broken soil, or habitations, do not enter this Hst, 

 and those belonging to the immediate margin of the sea are also ex- 

 cluded. All are, in fact, plants of a mountainous country, but con- 

 fined to the lowest levels.
