Mr. J. Miers on the Ehretiaceae. 209 



different dates, with his Bourreria spinifex and B. montana, 

 as will be presently shown, which renders the synonyms dif- 

 ficult of explanation.

 in costa valde sulcatis, nervis paucis immersis, arcuatim

 viter bifido 5 drupa globosa. — In Antillis : v. s. in herb. Mus. 

 Brit. , Cuba (Wright, 3118, sub nom. B. divaricata). 



This plant quite agrees with the characters given by Romer 

 and Sclmlz to their Ehretia spinifex. Dr. Grisebach, in 

 1862, referred a Cuban plant to this species, under the name 

 of Bourreria spinifex, quoting the synonym of those botanists ; 

 but in 1866 he converted this same plant (Wright, 3123) into 

 a new species, B. montana, which he pronounced to be distinct 

 from Romer and Schulz's species ; and at the same time he 

 referred Wright's plants 1365, 3118, and 3136 to his Bourreria 

 divaricata (not Don's), and synonymous with Ehretia spinifex, 

 R.& Sch. : I have shown the latter corresponds with Wright's 

 3118, while 1365 (in parte) and 3136 belong to Don's B. di- 

 varicata. Here is a sad confusion, which runs alike through 

 most of the determinations of Dr. Grisebach in this family, all 

 which have been made incautiously and in too much haste. 



This is a small shrub, with numerous divaricating branches, 

 which soon become bare and rugose from the decadence of the 

 leaves, the axils becoming somewhat spiniform ; the leaves, 

 solitary on each alternate node, are 8-10 lines long, 3-5 lines 

 broad, on a petiole 1-1| line long. The British-Museum 

 specimen has only a single flower, the others probably having 

 fallen away ; its calyx is 3 lines long, the tube of the corolla 

 5 lines, the lobes 1\ lines long. 



14. Bourreria microphylla, Griseb. Cat. PI. Cub. 210 ; — 

 ramulis tenuibus, teretibus, cinerascentibus, striatellis, gla- 

 bris ; foliis minimis, patentibus vel recurvis, ovalibus vel 

 suborbicularibus, coriaceis, valde convexis, supra profunde
