R. inerme can be maintained as a distinct species, there is no question that R. saxosum is distinct from it in several fairly marked characters.
The two varieties of the eastern Ribes hirtellum should bear the fol
lowing names.
Ribes hirtellum Michx., var. calcicola (Fernald) n. comb. R.
oxycanthoides, var. calcicola Fernald, Rhodora, vii. 155 (1905). R. hirtellum, var. saxosum (Hook.) n. comb. R. saxosum Hook.
Fl. Bor.-Am. i. 231 (1834). R. oxyacanthoides saxosum (Hook.) Coville, Contr. U. S. Nat. Herb. iv. 100 (1893) as to name-bringing synonym.

Ornithological Observations on Cleistogamy. anyone
whose winter rambles lead him along wet wood borders will take note
of clumps of Panicum clandestinum he will find the upper sheaths
split to shreds while still uninjured at the junction with the dry and
yellow blade above. A few winters ago the cause of this was made
known to the writer when watching a flock of chickadees near Takoma
Park, a suburb of Washington, D. C. These animated balls of gray and black were having a feast on the big fat grains of the cleistogam ous spikelets concealed in the sheaths. I have since found occasional
clumps of Panicum boscii also with shredded upper sheaths. Evi
dently the chickadees knew of this character of P. clandestinum and
profited by it before Linnaeus bestowed the name "clandestinum"
on the species because of it.— Agnes Chase, Bureau of Plant Industry,
Washington, D. C.
Vol. 13, no. 147, including pages 37 to 56, was issued 3 March, 1911.
