ENUMERATION OF THE SPECIES 61 



states that it was introduced into Petrograd in 1864. In England this Liukiu species 

 does not appear to have been properly known before 1911, when Mr. R. C. Notcutt 

 of Woodbridge exhibited it at the Royal Horticultural Society's Temple Show in 

 London. In 1915 I brought plants from Japan to the Arnold Arboretum. Of all 

 the red-flowered species of eastern Asia except the Formosan R. Oldhamii Maxim, 

 it is the least hardy. In Massachusetts it is a greenhouse plant and blossoms 

 sparsely. Miquel did not know the color of the flowers of his R. sublanceolatum 

 citing it as alba? which it certainly is not for no white form is known even to-day. 

 The color of the flowers varies from intense scarlet to rich magenta. Don gives 

 deep rose-color for the type and the scarlet-flowered form, which is the usual form 

 found growing wild, may be distinguished as f . coccineum Wilson, n. name. It is 

 unfortunate that we have to adopt Don's name for this species yet it is undoubtedly 

 the oldest since his description fits this plant and no other. He says that the leaves 

 are " ovate " a term not often applicable to the leaves of any Azalea, they are, how- 

 ever, broader in this species than in any other. Don cites as a synonym R. maxi- 

 mum Thunb., which is R. Mettemichii S. & Z., but no word of his description has 

 reference to this Eurhododendron. This Liukiu species has been cultivated round 

 Nagasaki and other towns in southern Kyushu I know not how long, but Don is 

 wrong in saying that it is native of Japan, though the mistake is natural when the 

 period he wrote in is considered. Komatsu bases his two species on slight differ- 

 ences in the shape of the leaves, in the color of the corolla and on the length of the 

 corolla-tube. Such trivial differences are unimportant in such variable plants as 

 the Azaleas of the Tsutsutsi section.
