Mr. J. Miers on the genus Larnax. 37 
Physalis gracilis (n. sp.) ;—caule gracili, substricto, pubescente ; 
folus ovatis, acutis, petiolatis, seepe inzquilateralibus, crassi- 
usculis, utrinque pallidis et pubescentibus, petiolo sublongo, 
piloso; floribus axillaribus, subsolitariis, pedunculo gracili, 
petiolo zquilongo, 1-floro, flore nutante ; calyce campanulato, 
profunde 5-partito, lobis acutis ; corolla cyathiformi- -campa- 
nulata, lutea, maculis 5 magnis violaceis notata, limbo 5-angu- 
lato, angulis obtusis ; Seine oot corolla brevioribus, filamentis 
brevissimis. —Real del Monte, Mexico, v. s. in heres Hook. 
(Coulter, 1222). 
The specimen is scarcely more than 8 inches long, with a 
single, slim, straight, apparently erect and somewhat branching 
stem ; the internodes are about 1 inch, the leaves 12 to 15 lines 
long, '8 lines broad, upon a slender petiole 4. lines in length, they 
are somewhat obtuse and unequal at base ; the more slender pe- 
duncle is about 6-8 lines ; the calyx, 5 fee long, is half cleft into 
five acute segments, and together with the peduncle i is hairy ; the 
corolla is 8 lines broad and 4 lines deep, the filaments are 3 lines, 
and the anthers nearly 2 lines long*. 
LARNAX. 
There exists a small group of plants in several respects ap- 
proaching Physalis as defined in the preceding page, but which 
differ in having fasciculate flowers, a corolla deeply 5-cleft, 
and in being herbaceous, erect, not prostrate plants. They vary 
from Cacabus and Thinogeton in the structure and colour of their 
corolla. The type is the Physalis subtriflora of the ‘ Flora Pe- 
ruviana,’ tab. 176, and two other plants described by Prof. Kunth 
are evidently congeneric with it. They differ from Saracha in 
their flowers being fasciculate, not decidedly unbellate, and in 
their inflated calyx, which subsequently closes the fruit, as in 
Physalis. They approach Margaranthus very closely, but they 
do not accord with that genus in the form of their corolla. The 
generic name proposed for this group is derived from XNdpva€, 
capsa, because the fruit is encased by the swollen calyx. 
Larwnax (gen. nov.).—Calyzx tubulosus, angulatus, tenuis, 5-den- 
tatus, demum augescens et vesicarius. Corolla tubo brevis- 
simo, campanulato- infundibuliformi, limbo 5-fido, lobis acutis, 
subpatentibus. Stamina5, brevia, tubo inclusa, zequalia, fila 
menta brevissima, anthere 2-loculares, loculis adnatis. Ova- 
rium ovatum, 2-loculare. Stylus brevis, erectus, apice sub- 
incurvus. Stigma sub-2-lobum. Bacca pisiformis, 2-locularis, 
* A figure of this species will be given in plate 39 B. of the ‘ Illust. South 
Amer. Plants.’
