A NATIVE of heaths, chiefly in mountainous places, not
very uncommon, but the Ihields are very rarely indeed to be
met with. Our fpecimen was gathered near Beverley, by R.
Teefdale, Efq. F. L. S.
Mr. Lightfoot has admirably defcribed this plant in his Flora
Scotica, and we think with him it ought not to be confounded
with L. flvndicus. However fimilar they may be in hue and general
appearance, they are different in ftruGure and fructification,
not to mention fize, which is variable. L. hifpidus is truly
fhrubby, round, filled with white fpongy pith, not flat nor
leafy. Its numerous branches form obtufe angles, and are a
little comprefled at their divarications, terminating in many
little briftly fpines. The fhields are terminal, horizontal^ concave,
polifhed, furrounded with an ereft margin of little unequal
prickles, fometimes branched and lengthened out. The
whole plant is polifhed and fmooth, of a brown or chocolate
colour, paler towards the root, the fhields and fpines darkey
than the other parts.
