savage and romantic mountains, which had so often been the

It consists of a few North American shrubs, with entire or 

 denticulate, membranous or downy leaves, and rose-colored or 

 white flowers in lateral or terminal panicles: distinguished 

 from the preceding by having the anthers opening lengthwise, 

 and by their five-angled, five-celled capsules, with five valves 

 having their margins closed by five other, external, narrow 

 valves. 



The Panicled Lyonia. L. paniculaia. L. 



A bushy shrub from three to eight feet high, conspicuous in the 

 early part of summer for its long and crowded panicles of white 

 flowers, and afterwards for its persistent, five-cleft seed-vessels. 

 The root is strong and tough. Its stem and irregular branches 

 are covered with a light pearly, ash-colored, stringy bark, which 

 on the last year's shoots is reddish, and on the recent shoots light 

 green, and often downy. The leaves are in bunches, or alter- 

 nate, on short, appressed stalks, lance-shaped, elliptic or in- 

 versely egg-shaped, entire, or minutely serrate, acute or acumi- 

 nate at each end, smooth above, lighter and downy beneath. 



Flowers in an irregular, terminal, compound panicle, with 

 small leaves at the base of the branches, and linear, brown, 

 very fugacious bracts; partial footstalks, thread-like, downy. 

 Calyx greenish, of five teeth, scarcely distinguishable by the 

 eye from the corolla to which it closely adheres. Corolla white, 

 nearly globose, with five minute, reflected teeth almost closing 

 the orifice. Anthers with doubly curved filaments, bringing 

 the anthers round the base of the pistil, which is nearly as long 

 as the corolla. 



Lyonia mariana, — Andromeda mariana of our botanists, an- 

 other beautiful plant, is found in Rhode Island, and probably 

 will be in Massachusetts.
