254 Mr. J. Miers on the genus Leucophyllum. 
blackish gray, in the younger leaves of a pale yellowish white ; 
the small branchlets are 4 to 8 inches long, almost bare, pro- 
minently knotty at the articulation of the fallen petioles, with 
only a few leaves towards the extremity, and with solitary flowers 
in their axils. Bonpland describes the stamens to be didynamous, 
quite glabrous, and the upper lobe of the corolla woolly within, 
and the tube pilose inside to the insertion of the stamens. Kunth, 
who probably examined very imperfect specimens, says, on the 
contrary, that it is quite smooth within, and that it has a convex 
palate marked with orange-coloured glandular spots, but I can 
perceive no indication of such a palate. In the above-mentioned 
specimens, the calycine segments are smooth within ; the corolla 
is also smooth, and hairy only in the mouth and upon the lobes 
of the border. Galeotti’s specimen, as I have before observed, 
has distinctly five fertile stamens, Hartweg’s has only four. 
2. Leucophyllum Texanum, Benth., DC. Prodr. x. 344 ;—ramis 
glabris, tortuosis, nodosis, subspinescentibus, junioribus to- 
mentosis; foliis obovato-oblongis, apice rotundatis, utrinque 
cano-tomentosis ; calyce extus tomentoso, laciniis lato-lanceo- 
latis, intus pubescentibus et 3-nerviis ; corolla precedentis, sta- 
minibus 4 didynamis, cum quinti rudimento, filamentis com- 
planatis, leevibus: capsula apice pilosa.—Mexico, Prov. Texana,

In this species the branchlets are more glabrous, more tortuous, 
and more knotty at the axils of the fallen leaves, often spimous 
at the short abortive branchlets, the leaves more obovate-oblong 
and rounded at the apex, the younger leaves incanous, not fer- 
ruginous, the calycine segments more oblong and broader ; the 
leaves are 7 or 8 lines long, 4 or 5 lines broad, the petiole bemg 
scarcely appreciable; the calyx is 14 line in length; the corolla, 
including the lobes of the border, is } inch long: the calyx, 
though persistent, does not increase in size in fruit ; the capsule 
is small, ovate, 12 line long, the two valves being inflected at the 
margin, very thick and coriaceous, and bifid nearly to the base. 
3. Leucophyllum campanulatum (n. sp.) ;—ramis substrictis, ra- 
mulis abbreviatis, approximatis ; foliis ovato-orbicularibus, 
crassis, utrinque densissime tomentosis, adultis incanis, jJu- 
nioribus confertissimis, ferrugineis; floribus axillaribus ideo 
arctis, folio superantibus, calycis lacinis crassis, lanceolatis, 
apice obtusiusculis; corolla preecedentibus dimidio majore, 
glabra, intus simpliciter hirta, ovarii apice, stylique basi, 
dense pilosis.—Mexico, v. s. in herb. Lindl. et Hook. (Zimapan, 
Prov. Mex., Coulter, n. 1271). 
This species is very distinct from the two former, its leaves
