Collected by J. N. Rose, at Mazatlan, June 17 to 19, 1897 (Nob. 1377 and 3102); at 

 Acaponeta, Topic, June 28 (No. 1491), July 30 (Nos. 3290 to 3292) ; at Eosario, Sinaloa, 

 July G to 10 (No. 3160) ; and near Colomas, July 18 (No. 3198). At Rosario I saw this

Besides the above 1 collected, near Dolores. Tepic, August 7, 1897 (No. 424), speci- 

 mens which, since the fruit is not mature, it seems best for the present to refer as a 

 form to this species, though they do not agree with it in all respects. They may be 

 described as follows: Low shrubs; young branches covered with large stellate 

 hairs; leaves oblong, rounded at base, obtuse and apieulate, pubescent above, with 

 simple hairs, but beneath densely stellate-pubescent, 3 to 7.5 cm. long on very short 

 petioles; stipules linear, twice as long as the petioles; ilowers solitary on peduncles 

 2 cm. long; buds shortly oblong, pubescent, with simple hairs, long-acuminate, 

 strongly angled at base; petals purplish at base; capsule truncate; carpels 7, 

 faintly reticulated on the back, inuticoee (?).

Sida holwayi Baker &. Rose, sp. nov. 



Stems erect 6 to 8 (?) dm. high, covered with coarse spreading stellate hairs and 

 a few longer simple hairs; branches ascending, somewhat naked above; leaf blades 

 oblong, 2.5 to 4 cm. (?) long, rounded at base, rounded or obtuse at apex, crenately 

 toothed, green and somewhat stellate above, paler and more densely stellate beneath ; 

 petioles shorter than the blades; stipules filiform, deciduous; Ilowers 1 to several in 

 the lower axils, becoming more or less glomerate towards the apex of the branch, 

 intermixed with purplish filiform bracts (stipules); fruiting pedicels 6 to 8 mm. 

 long; calyx 6 mm. high, angled, softly pubescent, with broadly triangular and acute 

 lobes; corolla yellow (?); capsule 6-celled; carpels somewhat reticulated on the 

 back, strongly reticulated on the sides, 2-awned, the body of the carpels 2 to 3 mm. 

 long, twice as long as the retrorsely hispid awns. 



Collected by E. W. D. Holway, Cuantla, Morel os, October 12, 1898 (No. 3043). 



Nearest S. ealciaefolia Presl, but of different habit and with pubescent broader 

 leaves, the inflorescence more congested towards the tips of the branches, sepals 

 broader, carpels larger and shorter-awned, etc. 



Sida neo-mexicana Gray, Proc. Am. Acad. 22 : 296. 1S87. Fide Baker f. 



Collected by J. N. Rose near Haejuquilla, Jalisco, August 24, 1897 (No. 2537). 

 Sida salviaefolia Presl, Reliq. Haenk. 2 :110. 1836. 



The typo of this species was collected many years ago by Haenke at Acapnlco, and 

 had not been collected again until recently, when Dr. E. Palmer (No. 1, 1895-96) 

 obtained it from the type locality. Mr. E. G. Baker in his revision made it a variety 

 Of S. xpinoxa, but I believe he now considers it a good species. It is remarkable for 

 the long retrorsely hispid awns of the carpels.
