XX. 9. THE RHODORA. 389 



logue for 1836, more than one hundred hybrid varieties are 

 enumerated, most of them beautiful. 



Sp. 2. The Upright Honeysuckle. R. nudijlbrum. Torrey. 



Azalea nudijibra. L. 



Figured in Abbott's Insects of Georgia, I, Plate 27. 



A low, spreading shrub, distinguished from the last by its 

 broader and fuller leaves and more highly colored flowers. 

 These are in bunches of six or more, radiating from one or two 

 points. The flower-stems are longer than the tube, deeply col- 

 ored and set with short hairs. Calyx of five, oblong, short se- 

 pals, unequal, with a row of hairs on the edge. Tube of the 

 corolla dark red, border shorter and of a fainter color. The 

 very prominent stamens are of a dark maroon color, as is the 

 still longer style. Stigma rounded, dark purple. 



This is found in the southern part of the State, towards the 

 borders of Rhode Island, and in several parts of Worcester 

 County, but far less abundantly than the last. It, however, 

 grows as freely in the open air, and shows the same tendency 

 to produce varieties and the same facility in hybridizing. Nine 

 distinct varieties, native or occurring in cultivation, are de- 

 scribed by Don, and forty-three additional ones are enumerated 

 in Loddige's Catalogue. 



The rhododendrons grow in almost any soil, if in a situa- 

 tion protected from the cold winds of winter and the burning 

 sun of summer ; and I have seen the maximum flourishing 

 where exposed to both. But they do best in a somewhat close 

 and tenacious soil, rather moist. They may be propagated by 

 cuttings, by layers or by seeds. The latter mode is considered 

 best; the seeds to be sown in peat soil or in fine, sandy loam, 

 in a shady border. When transplanted, they should have a 

 ball of earth left adhering to the roots. 



THE RHODORA. RHODO'RA. L.
