arisén in very rieh, damp soil, such as is otten to be found, near fishing 

 villages, among stonos and in the crevices of rocks. It is just under such 

 conditions that this species arises. The large, extremely luxurious leaves, dark 

 green on the upper side & otten septenate, even, on the flowering-shoots; the 

 enormous, many-flowered inflorescenee, the flowers of which, at the same tirae, 

 are rather small, the stalked glandules in the intiorescence, are characteristics, 

 which show, that this form has arisen in a fertile soil. R. insularis, on the 

 contrary, is found further from the dwellings of men, and often in woods. 

 Kor the authors, who attaché a greater weight to the presence or absence of 

 stalked glandules, in a systematic point of view, I will remark, that such 

 glanduleB are sometimes to be found on the oalyx of R. insularis (var. vul- 

 nerans). Likewise, I will refute the objection, that R. polyanthemos has 

 been found sometimes at a greater clistance from human dwellings, and together 

 with R. insularis, by the remark, that R. polyanthemos, after it has been 

 developed and has gained stäbility, under the above mentioned circumstances, 

 cau have wandered to other places and there retained its inherited disposition.
