298 THE JOURNAL OF BOTANY 
treated as a species collectiva, eee into three species: 4. borealis, 
A. arcticus, and A. Drummond- 
author had seen specimens previous to aay —_ 
Unalaska Island, N.W. America, and from Cape well in n- 
land (having examined no yellow rattles at all Pin British North 
merica, ah expects that connecting stations will be found); also 
(herb. Druce) Ben Lawers, Ben Heasgarnich, and two other 
localities in the Grampians. I believe it to be commoner in Scot- 
land than Drwmmond-Hayi, in company with which it sometimes 
grows; and it should occur in the ape peas as well as on the 
Snowdon group of mountains. M n gatherings, from mica- 
schist and granite, are as follows, but T pitepa certainly seen this or 
Drummond-Hayi on several other hills:—Ben Laoigh, 88 Mid- 
Perth (my aiicniie specimens of minor var. Drummond- Hayi from 
thence, and Mr. Druce’'s from Ben Lawers, are referred to Pole 
Ben-a- pee Glen Falloch, 87 or 88 West or Mid-Perth, 
ce. 3000 feet; Ben Chaisteil, near Tyndrum, 98 Argyle, c. 2000 feet; 
Aonach Bee ie ne Inverness, foe 2500 feet; and north-east slopes 
of Be pe, . Sutherland, above 2000 es It appears, 
therefore, to bd a thal hea plant i in Bri

This makes it coe 4 quote the description of A. arcticus 
Sterneck (1901) : :— Caulis 25 em. ot eed robustus, non nigro-strio- 
latus, alternatim hirsutus, sae multis, brevibus, ea parte 
media: ramosus, ramis multis caule paulo brevioribus, duobus vel tribus 
— paribus intercalarium inst» uctus. Folia caulina internodiis 
giora, anguste-lanceolata, in apicem attenuata, acuta, dentata, 
deutibus acutis, subpatuli is, folia inferiora in planta florente jam 
destruc ractes coc exceptis duobus paribus infimis, foliis 
interealaribus similibus, triangulares, in apicem longum products, 
rantes, entibne ays ree longioribus, superioribus 
Augusto.” It is only known from one station—Ocean Cape, 
Yakutat Bay, — N.W. America. 
Sterneck remarks that 4. Drummond-Hayi clearly belongs to 
the sabarnal s <i by its short internodes, narrow leaves, and the 
presenc leaves. The calyx x-pubeseence is 
similar to that of A. si ealis, which shows that the two are closely
