338 BOTANICAL GAZETTE [OCTOBER 
Professor J. M. Macoun, to whom I am indebted for much help, 
has collected in company with M. O. Motte a very interesting 
variety at Jasper Park, Alberta, on the low point running into the 
Athabasca River on the west side of the discharge of Beauvert Lake, 
July 30, 1917 (no. 95374, fr.; O.), which has glabrous or almost 
glabrous ovaries and fruits. It resembles S. chlorolepis, but the 
leaves of this species possess stomata in the upper surface which 
soon becomes glabrous, while in the western form the leaves are 
without stomata as in typical S. brachycarpa and have the same 
kind of pubescence. I also received a male specimen collected by 
J. M. Macown at the same place as the female type on July 23, 
1918, and I am giving the following description of this variety for 
which I propose the name: 
S. BRACHYCARPA var. glabellicarpa, nov. var —Frutex ut videtur 
parvus, dense et breviter ut in var. fypica ramosus; ramuli novelli 
vetustioresque ut in illa; folia conferta, anguste lanceolata, oblan- 
ceolata vel anguste elliptico-lanceolata, apice acuta vel subito 
apiculata, basi cuneata ad subrotunda, 7:2 ad 28:8 mm. magna, 
integerrima, sed infima pl.m. dense tenuiter glanduloso-denticulata, 
superne infimis exceptis pl.m. laxe villosula, vivide ( ?) viridia, esto- 
matifera, costa rubescente vel flavescente subimpressa nervis vix 
visibilibus, subtus discoloria, glaucescentia, densius villosula vel 
inferiora initio magis sericea demum glabrescentia, costa promi- 
nente, nervis lateralibus utrinque ad 8 angulo acuto a costa abeun- 
tibus vix vel paullo prominulis; petioli 1-3 mm. longi gemmis (an 
satis evolutis?) ad subduplo longiores; amenta pedunculo ad 
5 mm. longo normaliter foliato suffulta; mascula circ. 8:5 mm. 
magna ceterum a typo non diversa; fructifera circ. 1:1 cm. 
magna, subglobosa; ovaria sessilia vel subsessilia, glabra vel ad 
apicem parce villosa, stylo integro, stigmatibus siccis parvis bifidis 
ad 2. 5plo longiore coronata; glandula 1, ventralis, anguste ovato- 
conica, quam bractea obovata flavescens vel apice straminea 
utrinque laxe villosa subduplo brevior; fructus ovoideo-conici, 
4-5 mm. longi, ut ovaria glabra vel apice sparse pilosa. 
5. S. CHLOROLEPIS Fernald in Rhodora 7:186. 1905, is a species 
peculiar to the Gaspé Peninsula, where it was detected in 1905 at 
the headquarters of Ruisseau du Diable on the famous Mount
