A very doubtful species, of which I have seen no specimen. Number 

 of leaves as in G. uUginosum, but the prickles on the leaves, ac- 

 cording to the description in E. B., directed upwards like those 

 of G. erectum. Prickles of the stem pointing downwards accord- 

 ing to E. B., upwards according to Withering.

Plant small, very glabrous. Leaves of a thickish and rather soft tex-

 come shrivelled in drying. 



7. G. erectum {upright Bed-straw), leaves about 8 in a whorl 

 lanceolate mucronate their margins rough with prickles poiut- 



cipally the bark, to dye a red-colour ; boiling them with the yam and adding 

 alum to fix the colour. They also employ it as a rennet to curdle'milk, 

 adding the leaves of the stinging Nettle (Urtica dioica) and a little 9bU.
