314 RypDBERG: STUDIES ON THE RocKy MOUNTAIN FLORA 
PORTULACACEAE 
“Limnia utahensis sp. nov. 
Annual; stem 2-15 cm. long; basal leaves petioled; blades 
spatulate to linear, I-3 cm. long, 2-6 mm. wide; stem leaves 
connate, forming an oblique, 2-lobed disk, 1-2 cm. broad; inflo- 
rescence very short, corymbiform; fruiting sepals ovate, acute, 
2-3 mm. long, about equalling the pedicels; seeds about 1.5 mm. 
in diameter, minutely muricate. 
This species resembles in habit L. depressa (A. Gray) Rydb. 
and L. spathulata (Dougl.) Heller but differs from the former in the 
long and narrow blades of the basal leaves and more connate 
stem leaves, from the latter in the large and broad stem leaves, 
and from both in the large seeds. 
Uran: St. George, 1877, Palmer 56 (type, in herb. Columbia 
University) ; 1874, C. C. Parry 23 and 24. 
I have not seen the type of Montia Viae A. Nels.,* but from the 
description and specimens named by Professor Nelson I judge it 
is the same as Limnia depressa (Robinson) Rydb.} published a 
few months earlier. 
Coulter and Nelson report Calyptridium rosewm S. Wats. from 
western Wyoming, but I think this must be a mistake. Pr 
Professor A. O. Garrett and myself collected Talinum brachy- 
podum S. Wats. in southeastern Utah. Miss A. Eastwood has 
reported it from the same region.
