STUDIES IN THE CRUCIFERZ. 253 
in character of flower and fruit not very unlike some species 
of Draba, in aspect more like Cochlearia, but in vegetative 
characters distinct from both. The quite fresh and green 
herbage is nearly glabrous to the unaided eye, but a lens 
discloses a short and sparse pubescence of hairs partly sim- 
ple and partly forked or stellate. 
l. N.cnaNDIS. Draba grandis, Langsdorff in DC. Syst. ii. 
355 (1821). Peduncles about twice the length of the cen- 
tral tuft of leaves and 5 to 10 inches high: pods nearly 3 
lines broad and from orbicular to oval, on ascending pedicels . 
of $ to $ inch long. 
The specimens in hand were collected by Mr. J. M. Ma- 
coun at Langsdorff's original station, St. Paul Island, Behr- 
ing Sea, in August, 1896. The plant is said to inhabit damp 
rocky banks. In aspect it is much more like a Cochlearia 
than a Draba; and I suppose it is really the Cochlearia 
spathulata of De Candolle, Syst. ii. 369; though the charac- 
ter “siliqua lati lanceolata” can not be said to hold in re- 
gard to our plant. 
2. N. siLIQUOsA. Cochlearia siliquosa, Schl. in DC. 1. c. 
Native of the island of Unalaska; collected by Pallas. 
Distinguished by oblong petiolate leaves, lanceolate pods } 
inch long and tipped with a style bearing a capitellate 
stigma. 
Both the above remarkable plants have, by no very 
shrewd guessing on the part of American botanists, been 
referred to Draba hyberborea, Desv., a plant to which they 
bear extremely small resemblance. 
3. N. mEGALOCARPA. Central tuft of leaves 3 inches high 
or more ; leaves oblong-spatulate, obtuse, with a few coarse 
teeth near the summit: stout ascending peduncles 6 inches 
high, clothed below the raceme with oval sessile leaves 1 
inch long: pods linear-oblong, 3 to 2 inch long, 2 or 3 lines 
wide, acutish and tipped with an acute style.
