Rhododendron Harrovianum, /Hemsl. in Gard. Chron. 1910, vol. xlvii. p. 4; 
species ex affinitate 2. heliolepidis, Franch., a quo differt foliis angustiori- 
bus minus distincte apiculatis, corollae lobis acutis et staminibus exsertis.

cuneata, margine recurva, supra atroviridia, nitida, laevia, costa impressa, 
subtus creberrime lepidota, lepidibus parvis, costa valida, elevata; petiolus 
crassiusculus 4-8 mm. longus. Fores 3-5 in ramorum apicibus aggregati, 
pedicellati, pedicellis crassiusculis, 1-5-2 cm. longis saturate rubris albo- 
lepidotis. Calya brevissimus, obscure lobatus vel fere truncatus. Corolla 
campanulata, 2-2°5 cm. longa, lobis latis, extra parte inferiore saturate 
rubro-purpurea, albo-lepidota, lobis violaceo-purpureis, intus violaceo-

The Rhododendron that forms the subject of our figure, 
which has been drawn from material supplied by Messrs. J. 
Veitch & Sons from a plant that flowered in their nursery 
at Coombe Wood in April, 1909, is one of the hardiest of the 
species newly introduced from China, where it was dis- 
covered by Mr. E. H. Wilson. All the plants now in 
cultivation have been raised from imported seeds, but 
judging by its appearance and by the behaviour of allied 
species, it is probable that its propagation by means of 
cuttings may be successfully accomplished. R. Harrovianum, 
which flowered at Coombe Wood for the first time in 1907, 
has grown well there under conditions adapted to Rhodo- 
dendrons in general; a peaty, sandy soil and abundant 
moisture. In addition to R. heliolepis, Franch., to which, 
as Mr. Hemsley points out, it is nearly allied, our plant may 
also be compared with R. coombense, Hemsl., figured at 
Aprit, 1910,
