PHACELIA HUMILIS T. & G., var. Congdoni (Greene), comb. nov. 
P. Congdoni Greene, Pitt. v. 22 (1902). 
Until the capsule is broken and about half a dozen seeds roll out 
no one would have any hesitancy in referring Greene’s plant to 
P. humilis. The latter species, however, develops normally only 
four seeds. In view of the fact that other species of the section 
Euphacelia occasionally develop more seeds than usual, it seems 
sensible to regard P. Congdoni as representing such a condition in 
the case of P. humilis, especially since it apparently possesses no 
other points of difference. In this connection it seems worth while 
to quote Brand’s opinion in regard to P. malvifolia, var. loasifolia 
(Benth.) Brand, since the relation of this species and its variety 1s 
analogous to that of P. humilis and its variety. ‘ Diese Form 
(loasifolia] wurde bisher wegen der grésseren Anzahl der Ovula zur 
Sektion Eutoca gestellt. Sie stimmt aber in allen anderen Bezie- 
hungen so vollig mit P. malvifolia iiberein, dass sie meiner Ansicht 
nach nicht von dieser Art getrennt werden kann.”

P. minima is a delicate little annual referable — because of the 
few-seeded capsule — to the section Euphacelia. Its characters 
suggest a rather close relationship to P. Eisenii but the few long- 
pedicelled flowers, included stamens and opposite leaves preclude
