178 Rhodora [Jut* 



fore the new leaves from April 10 to May 15 in erect compact 8-tO 

 12-flowered clusters which are from 4 to 6 cm. long; corolla rotate, 

 scarcely two lipped, about 3 cm. wide, the narrow slightly glandular- 

 viscid tube about 5 mm. long, outside of the lobes sparingly lepidote 

 with 3-7 rows of scales; filaments exserted, from 1.6 to 2.0 em. long, 

 hairy below the middle, the tips upcurved and capped by bright rose 

 colored anthers; style with clavatc stigma, much shorter than the 

 stamens, recurved after anthesis; calyx lobes green, semicircular, 

 fringed with scattered 2 to 3 mm. long, weak mostly caducous cilia; 

 pedicels .5 to 2 cm. long, sparingly glandular-viscid; capsule .8 to 

 1.2 cm. long, lanceolate, truncate. Leaves oblong, 5 to 10 em. 

 long, 2 to 3 cm. wide, pointed at each end or rarely obtuse at base, 

 dark green above, pale as if glaucous and gray lepidote beneath, 

 petioles green or at length bright red or orange, 1 to 1.5 cm. long. 

 This form differs from the type in its pure white flowers, filaments 

 often villous nearly to the middle, stamens longer than the corolla, 

 the style much shorter than the stamens and the lower surface of the 

 leaves which as a rule are acute at both ends, usually pale and gray- 

 ish or silvery lepidote. 



The variety occurs in rocky woods and on cliffs, especially near 

 small streams, between 1500 and 4000 feet altitude along the Blue 

 Ridge in North Carolina, in McDowell and Buncombe Counties, 

 especially above Old Fort along Curtis, Jarrett and Mill Creeks; in 

 Rutherford County in Hickorynut Gap where abundantly associated 

 with R. minus; and in Polk and Henderson Counties above Tryon. 

 Type material collected by W. W. A., May 16, 190"), on the head- 

 waters of Mill Creek and since been in cultivation. A specimen 

 cited by Render as belonging to ]{. carolinianum, No. 4403, Biltmore 

 Herbarium, was collected near Tryon. Two trips have been made 

 to study this Rhododendron in this section where it is not uncommon 

 and many plants were found in full flower. All of these had pure 

 white flowers and this seems to be the color of all of the early flower- 

 ing plants in this section and in the collection cited above. 



The original station for the rose-purple form now in cultivation is 

 the eastern face of Grandfather Mountain, North Carolina, at an 

 altitude of about 5000 feet. It was studied there in April, 1914, 

 when in full flower and since that date other specimens of this form 

 have been collected at various stations in this general vicinity and a 

 plant of it cultivated, The rose-purple form along the Blue Ridge,
