CONTRIBUTIONS TO BOTANY. 
obtusely acuminate at the summit, attenuated at the base, and 
nearly equal in size, 5 lines long and 1 line broad in the widest 
part ; the stamens are 3 lines long, the filaments being slender 
below, swelling above into a thick, fleshy, fusiform conneetive, 
in which the two sterile anther-cells are extrorsely imbedded, 
the connective terminating in a curved excurrent point. The 
three ovaries are 7 lines long, 1^ line in diameter, 1 -locular, 
with six projecting parietal parallel placentae, each bearing a 
number of minute, almost peltate ovules, supported upon a short 
prominent funicle, with a horizontal or sub-ascending direction. 
The fruit is cylindrical, torulose, six-grooved, apiculated by the 
persistent style. If inch long, 1 inch in diameter; the peri- 
carp is thin and coriaceous, extremely friable and of granular 
texture when dry ; it is unilocular, and filled with a mucilaginous 
pulp, of a pleasant, sweet, and subacid taste, which dries into a 
thin epidermis that invests the seeds, and leaves a vacuity in the 
centre, without the vestige of any division. This is contrary to 
the statement of Ruiz and Pavon and other authors, who de- 
scribe the fruit of L. biternata as being 6- or 8-locular. The 
seeds are very numerous, ovate, somewhat compressed, often 
subangular by mutual pressure, and are attached to the wall of 
the pericarp in a somewhat horizontal position by a small hilum ; 
they are arranged in six very distinct series ; they are about 
5 lines long, 4 lines broad from the hilum to the more convex 
side, and 3 fines broad in the other transverse direction. Their 
structure has been already fully described*. 
I have lately observed, in the herbarium of the Paris Museum, 
another undescribed species of this genus, the description of 
which I here append to the former: — 
3. Lardizabala infuscata, n. sp.; — volubilis, folds biternatis', 
foliolis ellipticis apice vix acutis vel obtusiusculis, puncto cal- 
loso onustis, terminalibus in petiolulum longiusculum cuneatis, 
lateralibus sessilibus basi insequalibus et obtusioribus, glaber- 
rimis, crasso-coriaceis, supra intense fusco-viridibus, nitenti- 
bus, simpliciter nervosis, nervis patentibus immersis, subtus 
pallidioribus brunneis, lucidis, costa nervis venisque promi- 
nentibus, marginibus revolutis integris vel obsolete crenulatis ; 
stipulis orbicularibus majusculis, fuscis ; racemis d axillaribus 
folio sub-brevioribus. — Chile Australis : v. s. in herb. Mus. 
Paris (Hombron, Voyage de PAstrolabe et Zelee). # 
This species is at once recognized from L. biternata by the 
* A drawing of this species, with full details of the structure of its 
flower and seeds, is given in plate 28 .
