ENUMERATION OF THE SPECIES 71 



The specific name here employed to designate this species is the oldest valid 

 name but it seems to have been quite overlooked. Burmann named the plant 

 Azalea rosmarinifolia in 1768. This is the oldest name but unfortunately it was 

 neglected for over a century and became invalidated under Rhododendron by the 

 R. rosmarinifolium Vidal, a Philippine species, some years before it was taken up 

 for Burmann's plant by Dippel. 



A form with larger flowers than the type is : 

 Rhododendron mucronatum f. Noordtianum Wilson, n. comb.

Pynaert states that this form was raised in the nursery of P. van Noordt & 

 Sons, Boskoop, from seeds collected from some plants introduced from Japan. I 

 can find no difference between it and the form long cultivated in Japan under 

 the name of 0-riukiu-tsutsuji (large Liukiu Azalea). It is considered in Europe 

 to be a very hardy form of the type. 



Very similar to the last-named form is: 

 Rhododendron mucronatum "Mattapan" Wilson, n. f. 

 Azalea "Mattapan" C. M. Hovey, Mag. Hort. XXVII. 190 (1861). 



This plant was exhibited for the first time before the Massachusetts Horticul- 

 tural Society on March 23, 1861, by C. M. Hovey, and described as " a new seed- 

 ling, flowers white with a yellowish blotch on the upper petals which are fringed 

 in the way of A. crispiflora." This handsome form is still in the Holm Lea collec- 

 tion and in other gardens round Boston, Mass. In some gardens this Azalea is 

 known by the name of "America." 



A form with double white flowers is : 



Rhododendron mucronatum f . narcissiflorum Wilson, n. comb.
