BIDENS FRONDOSA L. var. ANOMALA Porter ex Fernald, Rhodora 
S? Or. 1903. : 
' This variety is peculiar in having upwardly barbed awns, but 
the precise significance of their occurrence is difficult at present 
to judge. In a specimen of the corresponding form of B. connata 
Muhl., the var. anomala Farwell, I have observed numerous down- 
-wardly barbed awns in the same heads with upwardly barbed 
awns (Vasey, near Georgetown, Washington, D.C., September 
23, 1888, in U.S. Nat. Herb.). Wrecanp (Bull. Torr. Bot. Club 
26: 415. 1899) cites also similar material collected at Ithaca, 
New York. Frrnatp (Rhodora 15: 75. 1913) inclines toward 
regarding B. frondosa var. anomala as a geographic variety. He 
cites Pennsylvania, New Jersey, Delaware, also the region from 
Maine to Cape Breton Island for its distribution. It is interesting 
to note that out of many hundreds of specimens of B. frondosa 
that I have examined from Europe and America, there were ob- 
served only two instances of specimens of the var. anomala having 
been collected outside the range given by FERNALD. These plants, 
coming from Kansas and Nebraska, go further in showing the 
distribution to be very discontinuous.

BIDENS ANGUSTISSIMA H.B.K., Nov. Gen. et Sp. 4: 233. 1820. 
The type of B. angustissima is matched very well by ScHuLtTz © 
Breontinus’ type of B. linifolia (both in Herb. Mus. Hist. Nat. 
Paris), except that the latter has only simple leaves, while the 
former has tripartite leaves. Katt, in publishing the description 
of B. linifolia (Flora 68: 203. 1885), described the heads as dis- 
coid. But that rays were present on at least the Paris material 
is shown by Scuuttz Brrontinvs’ label, in his own handwriting, 
_ which reads, “achs. rad. calva ... .” Furthermore, PRINGLE 
(no. 6924, granitic ledges at altitude a 2895 m., Cerro Ventoso 
ee above F Pachuca, Hidalgo, Mexico, August 18, 1898) has collected ©
