be treated as species. I venture, therefore, to make the necessary 
changes, and it may be well to point out at the same time a few errors 
or inaccuracies that occur in those notes spoken of. 
Cardamine lucens (G. S. Torrey) n. comb. C. oligosperma var. 
lucens G. S. Torrey, Ruopora 17, p. 157. Leaflets 7-11 (as in C. 
oligosperma); petals very narrowly cuneate or oblanceolate, tapering 
gradually to the base, 2 mm. long, about twice as long as the calyx; 
pods 2 cm. long or less, a little over 1 mm. wide, their pedicels 4-14 
mm. long or sometimes longer (26 mm.) the lower usually much 
longer than the upper. 
Cardamine bracteata (O. E. Schulz) n. comb. C. hirsuta subsp. 
oligosperma var. bracteata O. E. Schulz (1903). C. oligosperma var. 
bracteata G. S. Torrey, Ruopora 17, p. 157 (1915). Leaves with 3-7 
leaflets, the upper pinnately parted rather than pinnate; petals 
spathulate (as in C. oligosperma, but smaller) 2 mm. long, not twice 
as long as the calyx; pods 2 cm. long or usually shorter, 1.5 mm. wide, 
the lower on pedicels 4-10 (or 14) mm. long; seeds orbicular with a 
narrow thin pale margin. 
C. oligosperma differs from the other two species by a more abundant 
(and longer) pubescence which extends to the ovary; by its longer 
seeds which are 1.5 mm. long and 1 mm. wide; and by larger flowers 
(3 mm. long) and short pedicels (2-8 mm. long). In all three species 
the number of seeds is about the same, namely 15-20 or less to a pod; 
but the seeds being much longer than broad in this species, the pods 
are often 2.5-3 cm. long. 
C. unijuga Rydb. may also be a distinct species if absence of bracts 
and fewer leaflets“are constant characters. According to Rydberg 
the pods have 8-12 seeds only, but his figure of the plant seems to 
indicate that there may be more sometimes. This plant appears to 
be nearest to C. bracteata. 
Some specimens collected about a shaded spring this season, make 
it seem probable that my plant referred to C. oligosperma var. unijuga 
by Mr. Torrey, may be a shade form of C. bracteata; however, further 
observations may be needed to prove it. The type specimen of C. 
bracteata grew in a sunny place. 
At the time my notes were written, nothing was known to me of 
Mr. Schulz’s monograph. My specimen of the plant distributed as 
true C. oligosperma in my sets of 1885 was not then where it belonged 
in my collection and therefore was not examined. The result was
