398 SUPPLEMENT. 



17. RHODODENDRON, L. P. 41, after fi. Ehodora, add : 



R. Vaseyi, GRAY. Shrub 5 to 15 feet high, nearly glabrous : branchlets wholly destitute of 

 strigose bristles : flowers rather preceding the leaves, from few-scaled buds : leaves obloug, 

 acute or acuminate at both ends, sparsely hirsute, at least the midrib and margins when 

 young, when adult 3 to 5 inches long and 1 or 2 wide : corolla pale rose-color, rotate- 

 campanulate, but irregular, somewhat unequally 5-parted ; upper lobes shorter and overlap- 

 ping, somewhat spotted, three lower diverging and widely spreading, all broadly obovate : 

 stamens 5 to 7, commonly 7 : capsule minutely glandular, oblong, acutish. Proc. Am. 

 Acad. xv. 48. Mountains of Jackson Co., N. Carolina, " seven miles southwest of Webster," 

 George R. Vasey, and Chimneytop Gap, Donnell Smith, flowering in May. Nearest R. Al- 

 brechtii of Japan. Requires some extension of the Rhodora subsection. 



R. Californicum, HOOK., p. 41. Extends north to Brit. Columbia; and the syn. R. 

 maximum, Hook. Fl., as to the Pacific coast plant, belongs in part, if not wholly, here. 



R. macrophyllum, DON, p. 42. This is not yet well made out ; but it was originally 

 described (from the collection of Menzies) as having corolla smaller than of R. maximum, 

 and white, and leaves large. It should therefore be to R. Californicum what R. maximum is 

 to R. Catawbiense. But it is doubtful if there are two true species on the Pacific coast. 



31. SCHWEINlTZIA, Ell. Two species, characterized thus : 



S. Odorata, ELL., p. 49. Scales of the stem broadly ovate, imbricating : flowers in a short 

 spike, hardly nodding : sepals oblong, about equalling the flesh-colored corolla. Gray, 

 Proc. Am. Acad. xx. 301. 



S. Reynoldsise, GRAY, 1. c. More slender, with smaller and remoter scales : flowers more 

 numerous and smaller, slightly fragrant, soon nodding and mostly secuud in the narrow 

 spike: sepals ovate or lanceolate, half the length of the white corolla. E. Florida 

 near the coast, on Indian River, &c , first found by Miss Mart/ C. Reynolds, flowering in 

 winter. 



33. PLEURICO" SPORA, Gray. P. 50 and 18, add : No hypogynous 

 disk-glands. Placentas apparently double the petals in number, commonly 8. 

 Seed-coat close and alveolate. 



P. fimbriolata, GRAY. Extends to Oregon : coll. at Waldo by Iloicell, and on the Colum- 

 bia at Hood River by Mrs. Barrett. 



34. NEWBERRYA, Torr. P. 50 and 18, add : Bract-like sepals 2 or 4, 

 linear. Disk of short and deflexed glands alternating with the stamens, Kow 

 two species : 



N. congesta, Torr., p. 50. Flowers densely crowded in a corymbiform glomerule : lobes of 

 the corolla ovate, one third the length of the cylindraceous or slightly urceolate tube: fila- 

 ments equalling the slender style: anthers narrowly oblong, the line of dehiscence close to 

 the connective: cauline scales ovate, obtuse, only slightly erose. Gray, Proc. Am. Acad. 

 xv. 44. Besides Dr. Newberry's original specimens in the Cascade Mountains of Oregon, 

 now found in coniferous forests of Mad River, N. W. California, Rattan. 



N. spicata, GRAY, 1. c. Flowers spicately crowded : corolla more campanulate, with oblong 

 lobes half the length of the tube : filaments not equalling the short style : anthers short- 

 oblong, the line of dehiscence somewhat remote from the connective : cauline scales narrowly 

 oblong, acutish, fimbriate-erose. Woods, in the mountains of Humboldt Co., California, 

 Rattan.
