Some years since there appeared in somemeadows in Berkshire an extraordinary quantityof a substance which gained the name of WaterFlannel. It overlaid the Grass to the thickness ofsome inches, was white on its under side, green onits upper, and was said to grow so rapidly that scarlet with a yellow edge and inteiior, aud beingpendulous had much the appearance of a CUvia or Blaud-fordia. The plant was a scrubby bush, with leaveslike those of cinnamomcum; but its brilliant flowersquite concealed the faults of habit. We now learnIrom the Botanical Magazine that it is one of discoveries in the Sikkim Himalaya andEastern Nepal, where it is not uncommon at eleva-tions of 10,000 to 12,000 feet, both in valleys and onthe mountain tops and ridges. It forms a slenderrather ugly sparingly leafy twiggy bush, with oftenvery ornamental flowers, which are extremely variable,aud even wholly dissimilar in colour aud often in t
