manifestfe, foliola paullo majora mucrone cuspidata, calyx corolla usque 

 ad medium quadrifida diraidio tantum brevier, lobis hispidulis. Fruc- 

 tus ignotus (2). This is said to be "a shrubby plant, six feet high, 

 growing in the savannas near Wartenberg " ; therefore doubtless in- 

 digenous. But its resemblance to the Indian M. ruhicaulis is striking. 

 In the absence of fruit the points above mentioned are all that are ob- 

 served. The adult leaflets are 4 or 4|- lines in length. 



Calliandra Houstoni, Benth. (5) and G. tetragona, Benth. (8) ; Leu- 

 coena pulverulenta, Benth. (6), mixed with some specimens o^ Acacia 

 villosa, Willd., and A. glahxita, Schlecht. Perhaps Lagasca's prior name 

 of A. penicillifera belongs to and should be revived for this species (in- 

 cluding A. cuspidata, Schlecht., A. hirta, Nutt., and A. Texensis, Torr. & 

 Gray). The unapt name of ^. cuspidata has been given by Cunning- 

 ham to a received phyllodineous species. Acacia spadicigera, Schlecht. 

 (343) was collected with male flowers only, in a cylindrical-oblong 

 spike, the stamens monadelphous. To this species, rather than to A. 

 sphcBrocephala (if the two are really distinct), should be referred Ber- 

 landier's no. 2145, gathered between Tampico and Tula, with mature 

 fruit only. The pod is similar to that of A. Farnesiana, only even 

 more thickened, oblong or ovoid-oblong, straight and pointed, 1^ to 2 

 inches long, the oval and turgid seeds imbedded in pulp.* 



Pithecolohium lanceolatum, Benth. in Hook. Lond. Jour. Bot. 3, p. 

 198 (17); Inga leptoloba, Schlecht.? in flower only (4), and I. erio- 

 carpa, Benth., perhaps also /. Xalapensis (10). 



The only Rosaceous plant is a Ruhus, said to climb 50 feet high, 

 with the main stem an inch thick. It does not well agree with any 

 species in the late Dr. Liebmann's revision of Mexican and Central 

 American Rubi ; perhaps it is a form of R. fagifolius, Schlecht., with 

 the leaves silky-pubescent underneath. 



There are two species oi Eugenia (193 and 312), the former agree- 

 ing with no. 1 33 of Coulter's collection, from Xalapa. 



The Melastomaceae are an Arthostemma (159), Glidemia paucijlora, 

 DC. ? (138), and Conostegia Xalapensis, Don, with the flower-buds con- 

 spicuously acuminate (207). 



Lythruni alatum, Pursh (300) resembles some of the northern varie- 



* Bei'lantlier's no. 3144 is Lysiloma desmostachya, Benth., in fruit. The pods are 

 remarkably large, being from 5 to 7 inches long, l^^ to 2 inches broad, the flat, char- 

 taceous or coriaceo-membranaceous valves neatly falling away from the scarcely 

 thickened persistent margin.
