The plant figured in the accompanying plate was raised by the Marquess of Headfort from seed of the type number of Rhododendron phoenicodon, Farrer 877, so there is no doubt as to its identity. Its taxonomic status, however, is a different problem, for it is only one of the many forms, subspecies or species, whichever we like to call them, belonging to the Neriiflorum series. In the Rhododendron Society's book the late Mr. H. Tagg lists it as a subspecies of R. neriiflorum, remarking that it is probably an equivalent of another subspecies, R. euchaites Balf. f. & Forrest. Until a thorough monographic treatment has been accorded this difficult group, however, it seems desirable to keep under the separate names given them by the late Professor Sir Isaac Bayley Balfour, those plants which are distinguishable in cultivation. If R. phoenicodon be compared with the typical R. neriiflorum figured at tab. 8727 of this Magazine, it may be noted that the plant here figured has more pointed leaves, fewer flowers and a much smaller calyx. Farrer describes R. phoenicodon as a small bush 6-8 ft. high, whereas R. neriiflorum is usually much dwarfer. R. phoenicodon grew on open slopes of the more stunted bamboo brakes on the Hpimaw Pass, altitude 3000 metres, in North-East Burma, the fiery scarlet and profusely borne flowers making a fine contrast with the dark green foliage and its white reverse." This whitish undersurface is caused by the presence of an immense number of papillae covered with wax, ordinary hairs being absent except for a few of a scurfy nature on the midrib. 66.
