Abstract
- When plants of <em>Sedum rosea</em> (L.) Scop. and <em>S. telephium</em> L. ssp. <em>fabaria</em> Syme are grown in competition at different altitudes it is found that the growth of the species is affected differentially. This effect is such that at low altitudes <em>S. telephium</em> is a larger plant than <em>S. rosea</em>, while the reverse is the case at high attitudes. The observed differences are caused by a marked sensitivity of the growth of <em>S. telephium</em> to differences in altitude, while<em>S. rosea</em> is very insensitive. The most probable cause of these responses would appear to be differences of climate. The influence of altitude in northern England on air temperature, saturation deficit and irradiance has been investigated in order to establish the magnitude of the differences which may cause these responses.
