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 very different plant 
later described first as E. bullatum by Klatt and later as E. Kunthianum 
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. scabrum to have 
been represented by Moritz’s no. 1365 from Venezuela (E. meridense 
Robinson), a plant very different from the fortunately preserved type 
of E. scabrum 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.—

{Eastern Brazil, acc. to Bak. 1. c.] 
No Colombian material of this species has been seen by the writer, 
but the original character, here summarized, has been subject to 
control from a clear photograph (in the Gray Herbarium) of the 
fragmentary type in the DeCandollean Herbarium in Geneva. 
16. E. leptocephalum DC. Shrubby, with reddish or purplish 
branches sparingly puberulent with short curved subappressed non-
