hvmilu^ L. (142, 302, 339), and the interesting Agdestis clematidea, 

 M09. & Sesse (146), of which Berlandier's no. 2367 is the female 

 plant, in fruit. Concerning this genus, see Grisebach, Erlaut. PI. 

 Amer. Trop. p. 4. 



Anredera scandens, Moq. (227), and the following Amarantacese (all 

 common weeds, except the first), Telnnthera gracilis, Moq. (287) ; Al- 

 ternanthera Achyrantha, R. Br. (179) ; Iresine celosioides, L. (221) ; 

 Gomj)lirena glohosa, L. (140) ; Cyathida achyranthoides, Moq. (254); 

 Achyranthes aspera, L. (359) ; Chamissoa cdtissima, H. B. K. ; Ama- 

 rantus paniculatus, L. (283). 



The single Laurineous plant in the collection is an interesting and 

 little-known one, viz. Miseinteca capitata, Schlecht., with flowers and 

 fruit. It well accords with the published description, except that the 

 cupule of the fruit (which is said to be red, and is probably somewhat 

 fleshy when fresh) is not sulcate, and its border is evenly truncate. 

 The fruit itself seems to be a nut rather than a berry, as may also be 

 inferred from the fact that the collector took the tree for an Oak. It 

 is " a tall tree " (375). 



The Euphorbiacete are Acalypha cdopecurotdes, Jacq. (304) ; an un- 

 determined Croton (192), G. Eleuieria, L., or near it (199, 243), and 

 the male of O. trichocarpiim, Torr. Bot. Mex. Bound., p. 196 (167) ; 

 Dalechampia scandens, L. (158''), and another species allied to D. con- 

 volvuloides (348), an Euphorbia near to or identical with E. hexagona, 

 Nutt. (157^*) ; E. pilidifera, L. (133) ; and E. dioica, H. B. K., which is 

 E. adenoptera, Bertol., and, according to Dr. Engelmann, E. anceps, 

 Benth., and Anisophyllum densijlorum of Klotzsch and Giirke, in their 

 recent dissection of the natural Linnasan genus (251). 



The Urticacea3 are Pilea microphylla, Liebm. (P. muscosa, Lindl., 

 &c. 172) ; an undetermined Ficiis (332) ; Dorstenia Contrayerva, L. 

 (198), and D. excentrica, Moricand (123) ; the interesting Castilloa 

 elastica, Cerv. (371) ; and a Celtis (nearly of the section Mertensia, 

 H. B. K.) which appears to be new, but which I am unwilling now to 

 describe as such (321). 



There is a common GalUtriche (143) ; an Artanthe (234) ; Peperomia 

 Berlandieri, Miq. (358) ; a Salix (178) ; Myrica Xcdapensis, H. B. K. 

 (204) ; and a Quercus, the same as Berlandier's no. 2194 (346). 



The Endogena3 of the collection are very few, consisting of the in- 

 florescence of a " Palm, 30 or 40 feet high, with flabelliform leaves, 

 used for covering roofs, and a sweet, edible fruit," apparently the same
