This species differs from all Neillias known to me in the setose glandu- 

 lar brancldcts, petioles and inflorescence. With iV. sinen.^-i^ Oliver and X. 

 ribcsioidcs Rehder it agrees in the glabrous receptacle, l)ut both species 

 differ in their many-flowered racemes, cylindric recej)tacle and in the 

 ovary being pubescent only at the apex; the former species differs further 

 in the short petioles about 5 mm. long, and .V. rlhcsioidcs in the sljort, 

 ovate, acutish and mucronulate sepals and in the pubescent under side of 

 the leaves. 



Spiraea prunifolia Sieb. & Zucc. var. hupehensis comb. nov. — S, hyperi- 



cifolia var. hupehensis Rehder In Sargent, PI. Wilson, i. 4.S0 (lf)b^). 



A reexamination of Wilson's No. 1754 and No. 2754 have convinced me 

 that these s])eclmens do not l>elong to S. hupericijolla from which they differ 

 considerably in their short stamens which are only about one third as long 

 as the petals, while in 8. hypericijolia they are about as long as the j)etals. 

 Furthermore the leaves arc elli])tic-oblong and bright green and do not 

 show tlie tendency toward Ihe obovate shape and the grayish color char- 

 acteristic of S, Jty per icif alia. From tyj)ical S. prunifolia the variety dif- 

 fers chleflv in the ulabrousness of the leaves and in the serration which is 

 reduced to 1 1 teeth on each side near the apex. 



The true S. hypericijolia occurs in northern China, 1^-eing represented 

 in our collection by a s])cclinen collected May, 1910, near YcnaTi Fu, Shensi, 

 by \Vm, Ptirdom (No. 340). 



Spiraea Martinii I.cveille in Fedde, Rep, Spec. Nov. ix. 3^31 (1911). — 

 S.fideescens Rehder in Sargent, PI. Wilson, i. 439 (1913), non Dippel (1893). 



China, Yunnan: jNIengtze, barren dry hills, alt. 5000 ft., A, Henry 

 (No. 10(1(5*2); Pe-yen-tsin, in collibus Ta-song-pin, April 4, 1916, Simeon 

 Ten (No. 39, frutex 1.5 m. altns); Yunnan-Fu, in vallibus dumosis, alt. 

 2000 m., April ^29, lOlf), 0, Schoch (No. 54). 



The study of additional nuiterial has convinced me that my 5. fulves- 

 cens is not sj)eciflcally different from S. Marfiui Leveille of which, however, 

 I have not seen the type. This is in so far fortunate, as the name S, ful- 

 vescens Ri^hder could not have been retained on account of the older homo- 

 nym S. J}ilvei>'cens Dippel which is a hybrid of the Spiraria-group. Simeon 

 Ten's specimen differs from the original description in the more pubescent 

 leaves and in their grayish green, not glaucous under side, while Schoch 's 

 No. 54 differs in the smaller, not 3-lobed leaves and in the less pul>eseent
