PHILADELPHIA MIOROPHYLLUS, Gr. PI. FendL, p. 54. Branches slen- 

 der, erect; leaves small, 6"-9" long, ovate-lanceolate or oblong, very 

 entire, obsoletely 3-nerved, shining above, pale, and minutely pilose be- 

 neath, narrowed at base into a very short petiole; flowers terminal, 1-3; 

 calyx 4-cleft, glabrous without, lobes ovate-lanceolate, toineutulose 

 within; styles connate to the apex, shorter than the stamens; stigmas 

 4, oblong; capsules snbglobose. Canon City, Brandegee. The speci- 

 mens received from Mr. Brandegee exhibit some of the characters of 

 P. serpyllifolhiSj Gr. (PL Wright, 1, p. 77.) The leaves are pubescent 

 above, some of them plainly 3-iierved and the lobes of the calyx silky- 

 pubescent without. But it is clearly distinguished by the size of the 

 leaves and the oblong stigmas. The hairs on the under side of the 

 leaves are appressed and covered with tubercles under the microscope, 



1 JAMESIA, T. & G. Calyx-tube very short, turbinate, adnate to the base of the 

 ovary ; lobes triangular-ovate, sometimes bind. Petals 5, obovate, convolute. Stamens 

 10. the alternate ones shorter; filaments linear, flattened, acuminate. Ovary conical, 

 1-celled, with 3-5 parietal, many-ovuled placenta- : styles 3-5. equaling the stamens. 

 Capsule included, incompletely 3-5-celled. dehiscent between the persistent, diverging 

 styles. Seeds horizontal, ovate, shining. striate-reticulate, the embryo in the axis of 

 the fleshy albumen. A low, diffusely-branching shrub, 2-3 high; leaves opposite, 

 petioled, ovate, mucrouately serrate/canescent beneath, as well as on the petioles, 

 calyx, and branchlets, with a soft, hairy pubescence ; flowers cyniose, in terminal 

 panicles. Bcnth. and Hook*
