Eupatorium turbinatum. Puberulum ; caule herbaceo stricto 

 bipedali; foliis subsessilibus ovatolanceolatis acuminatis inasqualiter 

 argute serratis basi trinervatis supra scabridis subtus cinereo-tomentu- 

 losis, venis laxe reticularis ; cymulis oligocephalis ramos fastigiatos 

 terminantibus ; involucro 30-40-floro obconico multiseriali, bracteis 

 gradatim imbricatis rigidulis 2-3-striatis lanceolatis acuminatis, intimis 

 linearibus disco adoequantibus ; corollis albis ? angustissimis breviter 

 5-dentatis; acheniis prcesertim ad angulos hirsutulis. — In a mountain 

 ravine between San Luis Potosi and Tampico, Palmer. No. 1075. 

 A somewhat peculiar species of the Imbricata division, but not of the 

 Cylindrocephala or Osmia section. Heads half an inch long.* 



Eupatorium rhodochlamydeum. E. malvcefolio aliquantum 

 simile ; caule herbaceo ultraorgyali ; ramis pube ferruginea et glandu- 

 losa tomentellis ; foliis oppositis, caulinis amplis late hastato-deltoideis 

 acuminatis inrequaliter dentatis longe petiolatis, ramealibus ovato- 



reinstate tlie genus, and to add Ageratum gkinduliferum, Schultz Bip. in Lieb- 

 mann's Mexican collection, which appears like the rest to be shrubby. All three 

 species, or at least the two of which specimens are in hand, agree with each 

 other, and differ from Ageratum in these characters : Involucrum pauei-pluri- 

 florum ; phyllis 1-2-seriatis sequalibus. Corolla fauce e tubo gracili subito 

 arnpliata, lobis angustis sat longis acutis. Achenia basi stipitato-attenuata. 

 Pappi paleae breves fimbriato-laciniatae. Frutices vel fruticuli Mexicani. 



0. arbutifolius. Ageratum arbutifolium, HBK. Nov. Gen. & Sp. iv. 149. 

 Stevia arbutifolia, Willd. ex Less, in Linnaja, v. 140. Phania arbutifulia, DC. 

 Prodr. v. 115. 



0. trinervius, Mocino, Ic. Fl. Mex. t. 527. Phania trinervia, DC. 1. C. 

 Known only by the drawing, recently published by A. DC. 



O. glanduliferus. Ageratum glandui 'iferum (at least the /3. albiflorum) 

 Schultz Bip. in coll. Liebm. 



Ageratum microphyllum, Schultz Bip. in Seem. Bot. Herald, 298, from 

 the Sierra Madre in Northern Mexico, is a remarkable fruticulose species, with 

 racemose heads (which are much more than five-flowered) and the involucre 

 imbricated in the manner of Ilofmeisteria. It is the plant of which Benthara 

 in Gen. Plantarum makes a second species of Decachccta, and which Hemsley is 

 figuring as such. From my specimen it is not quite manifest that the anthers 

 are inappendiculate ; and the pappus is very unlike that of Decachccta Ilwnkeana. 



* Eupatorium adenospermum, Schultz Bip. in Seem. Bot. Herald, 299, 

 Var. pleiantiium. Capitulis in ramis gracilioribus paucis 20-floris ; foliis 

 plerisque oppositis rigidioribus ovatis subcordatis dentibus multo majoribus 

 paucisque serratis. — I have this from Seemann's northwestern Mexican collec- 

 tion along with the form which Schultz described, and cannot doubt it belongs 

 to the same species, which is a very strongly marked one, but needs to be 

 characterized anew. 



Eupatokium longipes. Bulbostylis pedunculosa, DC. The latter specific 

 name is preoccupied in Eupatorium by a South American species. (No. oGO.)
