slope of the mountains until at the mouth of Disenchantment Bay, 
about 20 kilometers from Mount Tebenkof, it meets the sea. 
The conditions which favor the northward progress of the forest 
are: The low elevation of the coast region, the warmth of the ocean 
currents, and the prevailing southeasterly winds; while the opposing 
conditions are: The higher elevation of the mountains, the snow and 
ice which cover them, and the occasional northerly winds. 
Two zones are clearly represented in the flora of the Yakutat Bay 
region, one extending from the sea up to timber line, the other from 
timber line to the lower limit of perpetual snow. The conspicuous floral 
features of these zones are described by Mr. Funston in his field report. 
In its general geographic relationship the Yakutat Bay flora shows an 
almost exclusively cireumpolar origin, while in its differentiation from 
the circumpolar flora it conforms with that of Western British America 
and the mountains of Washington and Oregon. 
The appended catalogue of the collection contains 137 species and 
varieties of vascular plants and 27 of cellular plants. The determina- 
tion of the specimens in certain cases has been made by students of 
special groups, the name of each of whom is inserted in the proper 
place in the catalogue. 
CATALOGUE OF SPECIES. 
RANUNCULACES. 
Anemone narcissiflora L. Sp. Pl. i, 542 (1753). Type localities, the Alps of 
Austria, Switzerland, and Siberia. The specific name, apparently by a slip of the 
pen, was printed first ‘‘narcissifolia,” but was corrected in a subsequent edition to 
narcissiflora. 
Disenchantment Bay, August 13 (No. 114), nearly past flowering. The plant is 
abundant, ranging from 300 to 900 meters altitude. 
Ranunculus cooleyz Vasey & Rose, Contr. Nat. Herb. i, 289 (1893). The type 
specimens are those collected by Miss Cooley near Juneau, Alaska, and those of the 
present collection. 
On the summit of a mountain on the mainland southeast of Haenke Island, Dis- 
enchantment Bay, August 10 (No. 99), at an altitude of 1,000 meters. Only four 
plants were seen. lam wholly unable to agree with Professor E. L. Greene! in con- 
sidering this plant a close relative of Kumlienia hystricula (Gray) Greene, which is 
the Ranunculus hystriculus of Gray. In that peculiar plant the sepals are petaloid, 
being large and white like those of an Anemone, while the petals are reduced to 
minute stalked nectaries. In Ranunculus cooleye the sepals are of an herbaceous 
green color, while the petals have the large size, expanded form, and bright yellow 
color of an ordinary buttercup. 
Ranunculus reptans L. Sp. Pl. i, 549 (1753); 2. flammula reptans Meyer, Pl. Labr. 
96 (1830). Described from specimens collected in Sweden and Russia. 
Khantaak Island, July 31 (No. 81), along the margin of a fresh-water marsh. 
Ranunculus nelsonii (DC.), Gray, Proe. Amer. Acad. vill, 374 (1873) ; 2. recur- 
vatus nelsonii DC. Syst. i, 290 (1818). The type specimens were collected on the 
island of Unalaska by David Nelson. 
| Erythea, ii, 193 (1894) and i, 53 (1895).
