[By Baker in Mart. Fl. Bras. vi. pt. 2, 299 (1876) this species is said to 

 range to British Guiana and Peru.] 



For a species of such early date this was accurately described in 

 considerable detail, but it has been much misinterpreted by conti- 

 nental writers; thus Kunth mistook for it the ver}^ different plant 

 later described first as E. bulhdum by Klatt and later as E. Kiinihianum 

 by Hieronymus, who took up a manuscript name of Schultz-Bipon- 

 tinus. Both Klatt and Hieronymus appear to have been misled by 

 an earlier determination of Schultz into supposing E. scabruvi to have 

 been represented by Moritz's no. 1365 from Venezuela (E. mcridense 

 Robinson), a plant very dift'erent from the fortunately preserved type 

 oiE. scahnim which fully confirms the diagnosis of Linnaeus filius. 



15. E. punctulatum DC. Shrubby; stem round and nearly 

 smooth; leaves opposite, ovate-elliptic or -oblong, acute or acuminate 

 at both ends, rather finely- serrate with somewhat distant teeth, 3- 

 nerved, subglabrous, punctate beneath, 1 dm. long, 2.5 cm. wide; 

 heads cylindric, 8-9-flowered, 8 mm. long, sessile in fascicles of 3-5 

 at the ends of the branchlets of ample flattish terminal corymbs; 

 scales striate, closely appressed in about 4 series, finely 3(-5)-nerved, 

 darkened toward the obtuse or rounded tip; achenes glabrous. —

No Colombian nuiterial of this species has been seen by the writer, 

 but the original character, here sunnnarized, has been subject to 

 control from a clear photograph (in the Gray Herbarium) of the 

 fragmentary type in the DeCandollean Herbarium in Geneva.

 branches sparingly puberulcnt with short curved subappressed non-
