Rhododendrons, Deciduous (Azaleas). By W. Dallimore (Garden, 

 No. 1,596, p. 416; 21/6/1902). — A description of the best species in 

 cultivation, with photograph of the Azalea garden at Kew. — E. T. C. 



Rhododendron Griffithianum (Aucklandii) ? x Rh. arboreum 

 hybridum d", Hybrids of. By L. Wittmack (Gartmflora, p. 281, 

 pi. 1199 and 4 figs. ; 1/6/02). — Rh. Griffithianum was used as the seed- 

 bearing parent, the pollen being obtained from several varieties of Eh. 

 hybridum, 'Dr. Mil,' 'Koh-i-noor,' 'Gabriel Liebig,' and others. The 

 plate given represents a seedling from Rh. Griffithianum (white corolla) 

 crossed with Rh. hybridum 'Dr. Mil' (carmine-red). Characters be- 

 longing to both parents are present in the offspring. 



The influence of the mother is seen in the bark, the somewhat 

 lengthened axis of the inflorescence, the thick flower-stalks, large calyx- 

 lobes, and bell- shaped corolla. 



The strong growth, harder wood, thick leaves, and the beautiful 

 carmine colour of the flowers are characters transmitted from the male 

 parent. — J. P. 



Rhododendrons, Hardy Hybrid. By W. Dallimore (Garden, 

 No. 1,601, pp. 61-8, 26/7/1902; No. 1,602, p. 78, 2 8/1902).— An 

 interesting article on this subject, dealing fully with the R. Thomsonii 

 and R. Griffithianum and Smirnoivi groups. Several illustrations are 

 given.— E. T. C. 



Rhododendron King Humbert I. By Angiolo Pucci (Bidl. R. 

 Soc. Tosc. Ort. v. p. 138 ; May 1902). — Raised from seed by Sig. Giovanni 

 Chiari, gardener of Marquis Carlo Torrigiani. Vigorous, well-shaped 

 plant, with leaves oblong-lanceolate, 20 cm. long, clear, opaque green 

 above, very transparent below, smooth ; flowers united to the number of 

 15-20 in broad, compact corymbs at the ends of branches, lilifloro- 

 campanulate, more than 10 cm. in width, of very elegant shape, white, 

 with a delicate pink transparence, with small, dark crimson spots at the 

 base, the upper petal speckled dark red, undulate at the margins, slightly 

 odorous, stamens ten. The buds are pink externally and preserve this 

 colour until after opening of the flower, although it is then somewhat 

 less deep, and it is this which yields the roseate transparence to the 

 flower itself. 



From the shape as well as the scent of the flowers the new variety 

 probably arises from seed of a R. ponticum which has been fertilised by 

 some species or variety of a Himalayan Rhododendron. — W. C. W. 



Ribes Grossularia ? x R. nigrum $ . R. Schneideri, Maurer in litt. 

 By E. Koehne (Gartenflora, p. 409 ; 1/8/02). — The hybrid appears to be 

 a casual seedling from a Gooseberry pollinated by Black Currant. The 

 stems and leaves have no prickles, and in the smoothness of the interior of 

 the calyx tube and slight hairiness of the style the plant resembles the 

 Black Currant. The fruits are seedless, dark red, covered with fine hairs, 

 and of acid taste, similar in shape to those of the Gooseberry. Very few 

 glands are met with in the leaves. — J". P.
