BORRAGINACE.E. 421 



2. BOURRERIA, P. Browne. 



B. Havanensis, var. radula, p- 181. Add syu. : Cordia Fhridana, Nutt. Sylv. iii. 83, 

 t. 107, the corolla depicted in the figure and described in letterpress as "yellow." Probably 

 a mistake. 



3. EHRETIA, L. 



E. elliptica, DC., p. 181. Add syn. : E. exasperata and E. ciliata, Miers, Bot. Contrib. ii. 

 229, 230, founded on Liudheimer's specimens. 



5. TOURNEF6RTIA, L. 



T. mollis, GRAY, p. 183. Rediscovered on the arid plains of S. W. Texas, by Havard. 

 T. Monclovana, Watson, Proc. Am. Acad. xviii. 120, of adjacent Coahuila, appears to be a 

 form of this. 



6. HELIOTR6FIUM, Tourn. 



H. COnvolvulaceum, GRAY, p. 183. II. Californicum, Greene, Bull. Calif. Acad. i. 202, 

 a form of the Mohave plant (coll. Cooper, Parish, Lemmon, which is hispid rather than stri- 

 gose, and dwarf), remarkable for its glabrous nutlets (coll. Mrs. Latjne-Curran). They are 

 not so in Cooper's specimens ; those of Parish aud Lemmon are not in fruit, nor are those 

 of Palmer of S. W. Utah, which are more strigose iu pubescence. 



8. PECTOCARYA, DC. 



P. setosa and P. pusilla, p. 187, both occur northward as far as to "Washington Territory; 

 the former collected by Brandegee, the latter by Hoicell and by Suksdorf. 



9. CYNOG-L6SSUM, Tourn. 



C. grande, DOUGL., p. 188. Forms of this pass freely into the smooth and glabrous form, 



Var. Icfeve. C. Iceve, 1. c. Not rare from Tamalpais northward. 



The two dubious species forming the third division, now known in fruit, are to be excluded : 

 see p. 422, 423. 



10. ECHINOSPERMUM, Lehm., rather than S war tz. 



1. L^PPULA, p. 188. The first division of this section ( * ) is here re- 

 elaborated. 



Biennials, perhaps sometimes annuals. 



-H- Very small-flowered and loosely racemed: corolla and nutlets not over 2 lines lone;: leaves 

 thin and green. 



E. Virginicum, LEHM., p. 189. Nutlets of the globose fruit equably short-glochidiate over 

 the whole back : racemes spreading. Gray, Proc. Am. Acad. xvii. 224. 



E. pinetorum, GREENE. Nutlets of the hemispherical-subpyramidal fruit marginally 

 glochidiate with flattened prickles, and the depressed ovate dorsal disk only glochidiate- 

 muriculate : racemes erect : leaves small (cauline an inch or two long), narrowly oblong, 

 radical all acute at base. Gray, 1. c. Mountains of New Mexico, Greene, and of Arizona, 

 Pr ingle, Lemmon. 



E. deflexum, LEHM., var. Americanum, Gray, 1. c., p. 189. Nutlets of the globular- 

 pyramidal fruit only marginally glochidiate, the flattened dorsal disk unarmed and granu- 

 late-scabrous, rarely a few small prickles on an obscure midnerve. Extends southward to 

 Iowa on the Mississippi, G. H. Butler.
