colour, witli darker veins on the lobes, and obscure spots 

 on the tube within. It remains to be seen whether the 

 change of colour will prove permanent ; such as it is, there 

 has been no alteration in the treatment of the plant that 

 would account for it, and so curious a case of coloration 

 appears worth a place in this Magazine. 



I need hardly observe that the species and even indi- 

 viduals of Rhododendrons vary greatly in colour, but the 

 sport is usually from a dark to a light colour, as in the 

 case of the rose-coloured and white variety of R. arboreum ; 

 these occur in nature, but I am not aware that the change 

 has occurred in one individual under cultivation. 



It remains to observe that the specific name of argenteum 

 must give place to that of grande, under which the plant 

 was published in India, in 1848, by Dr. Wight, in his 

 " Icones Plantarum India3 Orientalis," from dried specimens 

 collected in Bhotan by Dr. Griffith, that is, the year 

 previous to the publication in England of the " Rhodo- 

 dendrons of the Sikkim Himalaya," and before Dr. Wight's 

 work had reached this country. The figure in the latter 

 work no doubt represents a starved state or variety, with 

 elliptic-lanceolate leaves, long slender petioles, a very 

 dense bracteate head of flowers only three inches in 

 diameter, and small quite regular corollas only one inch in 

 diameter. 



I may further here remind horticulturists that B. Auck- 

 landii must bear the name of R. Griffithianum, and for the 

 same reason, as indicated under the figure of that plant in 

 Tab. 5065 of this Magazine. It was figured under the 

 latter name, also from Bhotan specimens, in the same part 

 of Wight's "Icones" (Tab. 1203), a figure as little worthy 

 of the plant as is that of R. grande in the same work. —
