xviii. (cont.)-^NEW RHODODENDRONS.t 

 Rhododendron adenopodum, Franchet. 



The well-known Frencli missionary, the Abbe Fargeg, appears 

 to have first discovered this interesting* and distinct rhododendron. 

 In a letter to Kew, Mr, Maurice L. de Vilmorin, of L^s Barres^ 

 informs us that ho received seeds from the Abbe in 1901, collected 

 in Eastern Szechucn. A plant raified from them flowered with 

 Mr. de Vilmorin in 1909* It is very distinct among rhododen- 

 drons in its oblanceolate leaves, clothed beneath with a dense, 

 brownish-white felt. On the plant at Kew (introduced by Wilson 

 from Western Hnpeh in 1904) the leaves are sometimes 6 in. long, 

 but only about If in. wide; smaller ones are 3 in. long by ^ in. 

 wide. The flowers are produced, four to six together, in a loose 

 truss. Corolla broadly campanulate, 3 in. wide, five-lobed, pale 

 rose; calyx-lobes | in. long, oblong, ciliate; stamens ten, pubescent 

 at the base of the filaments ; pedicels and fruits hairy. 



Mr, de Yilmorin compares the flowers to those of the hybrid 

 H. I'ewense; the resemblance is seen in the loose truss, the widely- 

 open corolla, and in its delicate rose colour. The bush grows as 

 much as 10 ft. high; it is apparently quite hardy and a good 

 grower. 



Rhododendron argyrophyllum, Franchet. 



According to Mr. E. H, Wilson, who introduced this species to 

 cultivation about 1904, it is one of the commonest rhododendrons 

 in Western Szechuen, China. It is found there up to 20 ft. in 

 height. The young shoots in the typical form are clothed with a 

 loose scurf, but in some forms are glabrous or very soon become so. 

 Leaves oblong-^lanceolate, cuneate to rounded at the base, 3 to 6 in. 

 long, I to lA in. wide, glabrous above, clothed beneath with a 

 close, compact felt; petiole about | in. long. The flowers are borne 

 in a loose truss, about ten together; corolla broadly funnel-shaped, 

 IJ in. in diameter, shallowly five-lobed, white or slightly tinged 

 with pink, with deeper pink spots on the upper side. The calyx 

 is small, its lobes triangular; stamens twelve to fourteen, shorter 

 than the corolla, the filaments pubescent towards the base; ovary 

 pubescent ; style glabrous ; fruit about 1 in. long, slightly 

 pubescent. 



The species was originally discovered by the Abbe David, about 

 1885. It appears to be quite hardy, but grows slowly. 



♦ Ribes wollense.— Since the description under this name of the shrubs 



growing at the Woll, Hawick, N.B-, appeared in these pages (K. Ji,, 1914, 

 p. 49), fresh flowers and further material have been examined. Ifc now 

 appears certain that the shrnbs in question are not of hybrid origin, but 

 belong to Rihes divaricatum, Douglas. The name wolleme must therefore 

 disappear. The plate also needs correction, and should read Bihes 

 divaricaium,
