numerous serratures : corolla more broadly funnel-form, the limb 12 to 

 15 lines broad; calyx-teeth slender, nearly equalling the tube. — A 

 shrub, 5 to 8 feet high, in gravelly ravines about Guaymas. (112.") 



Cordia (Myxa § Spiciformes) Palmeki. A shrub, 4 or 5 feet 

 high, the young branches and lower side of the leaves finely pubescent : 

 leaves oblong-lanceolate, attenuate at base, very shortly petiolate, acut- 

 ish, rather coarsely toothed, scabrous above, 1 to 2^ inches long by 3 

 to 6 lines broad: spikes pedunculate, loose, tomentulose, 1 to 1A inches 

 long: corolla 3 lines long, twice longer than the calyx: fruit red, ex- 

 serted, nearly 3 lines long. — " Yerba del pasmo." In ravines in the 

 high mountains above Guaymas. (281.) 



Bourreria Sonorje. A shrub, about 10 feet high, with stout 

 very leaf}' branches : leaves very roughly papillose-scabrous above, 

 soft-pubescent beneath, obovate to oblong-spatulate, obtuse or retuse, 

 attenuate to a very short petiole, entire, 1^ inches long or less : flow- 

 ers few on slender pubescent pedicels 2 to 5 lines long : calyx cleft 

 to the middle, the deltoid lobes acute, half the length of the corolla- 

 tube ; corolla greenish yellow, puberulent, 5 lines long, the lobes 

 oblong, acute; filaments glabrous, exserted : fruit black, depressed- 

 globose, 2| lines broad. — Near a waterfall in the mountains above 

 Guaymas. (289.) 



Coldenia* angelica. Annual, prostrate, wide-spreading, some- 

 what hispid : leaves ovate to rhombic, acute, strigose-hispid on the 

 margin and finely appressed-pubescent, entire or the margin sinuate, 

 irregularly 2-3-nerved each side of the midvein : calyx nearly 2 lines 

 long, the narrowly acuminate hispid lobes nearly twice longer than 

 the tube ; corolla " mauve," 3 lines long ; filaments slender, adnate 

 nearly to the middle, with a short obtuse prominent appendage at 



* Two other species of this genus may be defined as follows : — 

 C. brevicalyx. White with a close fine pubescence and scarcely at all 

 hispid : leaves very like those of C. angelica in form and veining: calyx very 

 short (1 line), the broadish acute lobes shorter than the tuhe; corolla 2 lines 

 long; filaments slender, slightly dilated below the insertion: nutlet subglo- 

 bose, much smaller; embryo similar. — Confused with the true C. Palmeri 

 as to characters of flower and fruit. Ou the lower Colorado (Palmer, 1869; 

 C. Palmeri, Gray, Proc. Am. Acad. 7. 292, and Syn. Fl., in part) ; San Ber- 

 nardino (147 W. G. Wright, 1880). 



C. Palmeki, Gray. Limiting the species to the one of Palmer's original 

 specimens which has the leaves " plieate-lineate by about G pairs of straight 

 and strong veins," it may be otherwise distinguished by the 5-parted calyx (1^ 

 lines long), the lobes linear and acute. The corolla is 2 \ lines long, with the 

 rather stout fi'ament somewhat dilated below the insertion. The fruit is 

 unknown.
