As stated by Ker this hybrid was "raised by Mr. Herbert at Spofforth near 

 Weatherby, from seed ripened on the common white glaucous-leaved Azalea in 

 the flower of which the pollen or dust from the anthers of Rhododendron maximum 

 had been purposely substituted for that of its own flower." The evergreen leaves 

 are oblong, acute at both ends and glaucous beneath; the flowers are rather small, 

 whitish, the lobes with a pinkish border and the upper lobe spotted yellow, the 

 tube cylindrical. I am referring to R. hybridum, though not without some doubt, 

 the R. azaleoides as described by Mr. Bean, which according to his opinion possibly 

 is a hybrid of R. viscosum and R. maximum and Mr. Bean's judgment can be de- 

 pended upon. Also a specimen I collected nearly twenty years ago at Kew as 

 R. odoratum agrees much better with Ker's figure than with that of R. fragrans 

 Paxton, though the corolla-tube is not so cylindrical as represented in that figure.

the plate bearing the name R. azaleoides alba odorata. 



Sims states that this is a hybrid raised by Wm. Herbert from seed of a white- 

 flowered Azalea fertilized with the pollen of R. ponticum; the flowers are very fra- 

 grant, rather small, funnel-form, white, slightly tinged lilac, the upper lobe dotted 

 green. Reider's R. azaleoides may belong here though the upper lobe is not dotted 

 green.

1 A specimen collected by me at Kew Gardens in 1901 as R. odoratum apparently 

 belongs here and certainly is the hybrid described by Bean as R. azaleoides, while 

 another specimen in the herbarium of the Arnold Arboretum collected by H. Zabel 

 in the Botanic Garden at Muenden, Hanover, from a plant received in 1882 as 

 R. odoratum from T. Smith in Bergedorf near Hamburg, is not the same and similar 

 to R. azaleoides. 



2 As R. fragrans Paxton must be considered a duly published name, it invali- 

 dates R. fragrans Maximowicz of 1870, for which I propose the following new name: 



Rhododendron Adamsii Rehder, nom. nov. 



Azalea fragrans Adams in Mem. Acad. Sci. St.-Petersb. II. 332, t. 14 (1808). 

 Azalea pallida Turczaninow in Bull. Soc. Nat. Mosc. 1838, 96 (1838), name 

 only.
