70 MISSOURI BOTANICAL GARDEN. 
about 6X8X22 mm. in the Floridan specimens, though in 
the few Missouri specimens that I have seen it was of 
scarcely more than half this size. Its surface is coarsely 
rugose-reticulated over the firm fibrovascular bundles of 
the pericarp. Near the top it is marked by an oblique scar 
left by the caducous style, and it contains a single large 
seed with a straight embryo and a rather thin layer of 
albumen. * 
So far as can be made out at present, the Missouri 
Leitneria differs from that of Florida only in its larger 
size,— the southern plant being described as a shrub 2 to 
6 feet high,—in its somewhat larger more coriaceous 
leaves rarely more than acute at apex, while those of the 
Floridan plant are usually somewhat acuminate, and in its 
apparently smaller fruit. Neither of these characters, 
however, need of necessity be of specific value, nor repre- 
sent more than individual variation due to habitat, climate, 
or age. 
In an account accompanying his illustrations of. Leitneria 
Floridana, Professor Oliver | mentions ‘‘ specimens of per- 
haps a second species of Ledtneria from Texas, collected by 
Drummond; ’’ and Bentham and Hooker { and Hemsley § 
admit this probable second species. In reply to an inquiry, 
Professor Oliver writes me that the material of this form 
consists of imperfect specimens without original label but 
labeled by Sir William Hooker as from ‘Rio Brazos, 
Texas, Drummond; ’’ and he adds that so far as these 
specimens go, he does not now see any reason why they 
should not belong to LZ. Floridana, though the catkins are 
* Except for the extrorse placental suture, and the lacunose bracts 
and axis, the structure of the pistillate flowers is well shown by Baillon, 
f. 215; Heim, pl. 10, f. 7 to 10; and Oliver, f. 6 to 8 — where the position 
of the stigmatic groove is correctly shown, but the placenta inverted. 
The fruit and seed characters are also shown by Baillon, f. 216; Heim, 
pl. 10, f. 11 to 22; and Oliver, f. 9.
