396 SUPPLEMENT. 



var. heterodooca, Syn. El. 12, chiefly. From the northern Aleutian Islands, Harrington, 

 Dall, &c., to Sitka, Mertens, and Kodiak, Kellogg, the latter most broad-leaved and peculiar ; 

 the narrower-leaved passing into the preceding variety. 



Var. velutina, DC. Fl. Fr. Suppl. 432, with whole herbage canescently pubescent. 

 Sand-hills of Burt Lake, Michigan, E. J. Hill. 



C. Rever chord. (In a separate subdivision before C. aparinoides.) Annual, hirsutulous 

 below, glabrous above : stem a span high, slender, erect, cymosely and effusely much- 

 branched : leaves sparingly dentate, half-inch long ; radical spatulate, lower cauliue lanceo- 

 late, those of the upper branches almost filiform and entire : flower and fruit erect on almost 

 capillary peduncles : corolla blue, oblong-campauulate, with ovate-lanceolate lobes rather 

 .shorter than the tube : capsule obovate, crowned with the somewhat shorter narrowly linear- 

 lanceolate erect calyx-lobes, opening near the base 1 On granite rocks, House Mountain, 

 Llano and Burnet Co., Texas, Reverchon, May, 1885. 



5. HETEBOC6DON, Nutt. P. 14, add: - 



H. MINIMUM, Kellogg, Proc. Calif. Acad. vii. Ill, by the character is clearly Alchemilla 

 arvensis. 



ERICACEAE. 



1. GAYLUSSACIA, HBK. 



G. frondosa, TOKR. & GRAY, p. 19. To this is to be added : 



Var. nana. Stems lower and strict, only a foot or so high : leaves more reticulated in 

 age and smaller than in the ordinary plant : racemes and their pedicels shorter. Pine bar- 

 rens of Florida, &c. Apparently there the commoner form, of which the var. tomentosa 

 is a downy-leaved state. 



2. VACClNIUM, L. 



V. OxycoCCUS, L., p. 25. To the slender and chiefly high-northern form of this belongs 

 Oxi/coccos microcarpa, Turcz. Fl. Baic.-Dahur. ii. 195. To this (as being the original 

 species), rather than to V. macrocarpon, is referred the connecting form of the Pacific 

 coasts, viz. : 



Var. intermedium. Leaves from ovate to oblong, mostly obtuse, a third to half 

 inch long : flowers strictly umbellate from the scaly bud, but this not rarely proliferous into 

 a leafy shoot (in the original of the species very rarely so) : berry 4 or 5 lines in diameter. 

 Washington Territory and N. Oregon, Suksdorf, Henderson. Also, doubtless, Douglas, in 

 Hook. Fl. ii. 35, referred to V. macrocarpon, very naturally, as leaves of the specimen are 

 elliptical, obloug, very obtuse, even more so at apex than base, obviously veiny beneath, and 

 margins hardly at all revolute. (N. E. Asia, Sachalin, Japan, &c.) 



V. macrocarpon, Ait., p. 26. Pedicels becoming scattered along the base of a leafy shoot 

 proliferous from the scaly bud, either squamaceous- or leafy-bracted. 



4. ARBUTUS, Tourn. P. 27, add: 



A. LAVRIFOLTA L. f. The original of this is probably a specimen of A. Unedo (doubtless 

 of the Old World), in the herbarium of Linnanis, on which Smith has written this name. 

 The A. Iqurifolia, Lincll. Bot. Keg. xxv. t. 67, is surely A. Xalapensis, HBK., a variable Mexican 

 species. The North American forms, other than the A. Menziesii of the Pacific coast, are very 

 difficult, but seem to be best disposed as follows : 

 A. Xala/pensis, HBK., var. Arizonica. Tree 20 to 40 feet high, with a whitish and 



thickish scaly bark on the main trunk, but with the reddish close and thin bark of A . Men-
