1468 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM 



Heheclinium liebmanniae Hook. f. & Jacks. Ind. Kew. 1: 1097. 1893, by error. 



Veracruz; type from Mirador. 



Shrub with slender terete flexuous branches, finely tonientellous or incurved- 

 puberulent; leaves opposite, ovate, slender-petioled, acuminate, sharply serrate, 

 palmately 3 or 5-nerved from near the base, membranaceous, green and smoothish 

 on both surfaces; heads 35 to 40-flowered, in compound leafy-bracted panicles; 

 phyllaries lanceolate to lance-oblong, acute. 



DOUBTFUL AND EXCLUDED SPECIES. 



CoNOCLiNiUM {E upatorium) album Mart. Linnaea 24: 194. 1851. Described 

 from greenhouse material of Mexican origin and said to be a smooth half-shrub 

 with somewhat deltoid acuminate serrate leaves, 3 to 5-headed corymbs, 24 to 

 30-flowered heads, and pappus of 13 bristles. The species is wholly obscure and 

 in any event the name under Eupatoriutn is unvailable, owing to the earlier and 

 still valid homonym. 



EuPATORiUM KARViNSKiANUM DC. Prodr. 5: 163. 1836. De Candolle, de- 

 scribing this species from very fragmentary material, supposed it to be shrubby. 

 Later specimens secured by Pringle and others seem to show it herbaceous 

 throughout, and one collected by Galeotti is indicated on his label as an annual. 

 It is therefore omitted from the foregoing treatment. 



EuPATORiuM MicRANTHUM Lag. Gen. & Sp. Nov. 25. 1816. This wholly 

 obscure plant, to judge from its blue florets, imbricate phyllaries, and the few 

 other remarks regarding it, was presumably an Ageratum. There seems no satis- 

 factory ground for applying the name, as did Lessing (Linnaea 5: 138), to a 

 white or pink-flowered Eupatoriutn of Section Eximbricata. Lessing's E. mi- 

 cranthum must therefore receive the next later designation, namely E. ligustrinum 

 DC. Prodr. 5: 181. 1836. 



EuPATORiuM MiCROCEPHALUM A. Gray, Proc. Amer. Acad. 21: 384. 1886. 

 This is inseparable from Ophryosporus ovatifolius (DC.) Benth. & Hook, f.; 

 Hemsl. Biol. Centr. Amer. Bot. 2: 79. 1881. 



EuPATORiuM MiCROPHYLLUM A. Gray; Dur. & Jacks. Ind. Kew. Suppl. 1: 

 166. 1902. A clerical error for the preceding and therefore referable to Ophryo- 

 sporus ovatifolius (DC.) Benth. & Hook. f. 



EuPATORiUM OLiGOLEPis (Kunzc) Hemsl. Biol. Centr. Amer. Bot. 2: 98. 

 1881. ConocZiniMW oiigoiepis Kunze, Del. Sem. Hort. Lips. 4: 2. 1840. Vaguely 

 characterized and wholly obscure species, raised from Mexican seed in the 

 Botanical Garden at Leipzig. Said to have been suffruticose, with erect sulcate 

 pubescent stem, opposite, petiolate, deltoid-ovate, obsoletely sinuate-dentate, 

 pubescent leaves, short-pediceled heads in contracted terminal corymb, and 

 15 to 20 subserial phyllaries. 



EUPATORIUM PAPANTLENSE Lcss. Linnaea 6: 403. 1831. This species incom- 

 pletely described by (briefly and for the most part negatively stated) comparative 

 characters is still doubtful. It may have been only a form of the earlier E. 

 havane?ise H. B. K., to which in any event it seems to have been closely related. 



EuPATORiuM PETRAEUM Robinson, Proc. Amer. Acad. 41: 275. 1905. Trans- 

 ferred to Ophryosporus as 0. petraeus Robinson, Contr. Gray Herb. n. ser. 75: 

 4. 1925. 



EuPATORiuM POLYBOTRYUM DC. Prodr. 5: 174. 1836. From described 

 character and tracing of type, this can not with certainty be separated from 

 Ophryosporus ovatifolius (DC.) Benth. & Hook, f.; Hemsl. Biol. Centr. Amer. 

 Bot. 2: 79. 1881.
