pubescent petiolule, very acutely laciniate-denticulate, sparsely pubes- 

 cent above, subtoraentose beneath, 2 to 4 inches long : fruit 6 inches 

 long, oblong : seed obovate, nearly 4 lines long, the narrow rhaphe 

 prominent; radicle inflexed. — Hacienda San Miguel (F). Perhaps 

 the same that was collected by Mo9ino & Sesse (Icon. t. 94), referred 

 by De Candolle to E. cesculij'olium, a species from the coast of Cam- 

 peche. The petals of the latter are described as about five inches 

 long, very much longer than those of the figure given by Mogino & 

 Sesse, nor does the description accord in other respects with the present 

 specimens. The figure of Mogino & Sesse represents a short branch, 

 armed in part with short recurved prickles, with leaflets like Palmer's, 

 but less acuminate ; the pedicels are very short and stout, terminal 

 upon very short branchlets ; flowers pubescent, the calyx tubular (8 or 

 9 lines long) with broad ovate teeth, the petals (2| inches long) about 

 equalling the five stamens. 



Waltheria detonsa, Gray. Flowers opening in the evening. — 

 Hacienda San Miguel (20). 



GuAZUMA TOMENTOSA, HBK. A tree 15 to 20 feet high and one 

 or two in diameter, with soft white wood, used for making spoons and 

 other articles. The bark is made into ropes, and the inner part of the 

 fruit with the seeds is sometimes ground and made into cakes. — Same 

 locality (J). Known as " Guacima" or "Mexican elm." 



Atenia prSTLLA, Linn. — Same locality (21). 



Atenia Berlandieri. SufFrutescent, 3 to 6 feet high, densely 

 pubescent : leaves broadly ovate to lanceolate, acute or often shortly 

 acuminate, subcordate or rounded at base, coarsely serrate, sometimes 

 obscurely 3-lobed, densely stellate-tomentose beneath, at least when 

 young, much smoother above, 2 or 3 inches long or more, the petioles 

 6 to 12 lines long: peduncles fascicled in the axils, shorter than the 

 petioles, the umbels 3-5-flowered : flowers purplish brown, small, the 

 lanceolate acuminate sepals 11 lines long; blade of the petals 2-parted, 

 the lobes parallel : anthers 2-celled : ovary pubescent ; fruit 3 or 4 

 lines broad, on pedicels 3 to 5 lines long. — Same locality (19, 83) ; 

 also found by Berlandier in 1830 (n. 788, 2208) near Santander and 

 at San Rafael in Tamaulipas. 



Ayenia Palmeri. SufFrutescent, about 5 feet high, densely pu- 

 bescent: leaves on petioles 1 to 6 lines long, ovate, acute, subcordate 

 at base, occasionally obscurely 3-lobed, rather finely serrate, stellate- 

 tomentose beneath, smoother above, 1 or 2 inches long : peduncles 

 fascicled, slender, short, 1-3-flowered : flowers greenish, small, the 

 lanceolate acuminate sepals 1 1 lines long ; blade of the petals lunate :
