nate, alternate, petioled or sessile. Stipules in pairs at the base of the petioles, some- 
times wanting. Tendrils, when present, axillary, formed out of abortive peduncles. 
The type of this Order is the well-known genus Passiflora or Passion-Flower, no 
African species of which has yet been discovered, though P. caerulea (a native of 
South America) is now almost naturalised and apparently wild in some parts of 
or colony. The few South African species known have small or minute, greenish 
owers. 
TABLE OF THE SOUTH AFRICAN GENERA. 
* Lobes of the perianth in two rows, those of the inner row like petals. No involucel. 
I. Tryphostemma.— Each row of the perianth of 3 segments. Corona-staminea 
annular, double, the outer fringed. 
II. Modecea,-—-Each row of the perianth of § segments. Corona-staminea obsolete 
or wanting. 
** Lobes of the perianth (or calyx) in a single row. Involucral bracts present or 
absent, subtending the perianth. 
III. Ceratiosicyos\—A vine-like climber. Perianth 5- (or 4-) fid. Male flowers 
racemose, involucrate ; females solitary, without involucre. 
IV. Acharia,—A suberect, small herb. Perianth 3- (or 4-) fid. Male and female 
flowers involucrate, neither racemose. 
I. TRYPHOSTEMMA, Harv. 
Flowers hermaphrodite. Tube of the perianth short, conical ; limb 
6-parted, in two rows, the three inner segments unequal, two of them 
larger, herbaceous and albomarginate, the third linear and petaloid. 
Corona-staminea perigynous, annular, double ; the outer fimbriated, 
the inner entire or crenulate, bearing the stamens. Stamens 5, attached 
to the interior corona ; filaments subulate ; anthers erect, suagittate, 
2-celled. Ovary subsessile, unilocular ; ovules few, on three or four 
parietal placenta. Styles 3-4, filiform ; stigmas capitate. Capsule 
shortly stipitate, membranous, 3-4-valved, few-seeded ; seeds pendu- 
lous, enclosed in a membranous arillus, areolate-corrugate; embryo 
not seen. 
But one species known. The name is compounded of rpudos, a delicate fragment, 
and oréuua, acrown; in allusion to the depauperated condition of the crown of rays 
in this miniature Passion-flower. 
T. Sandersoni (Harv. Thes. t. 51). 
Has. Port Natal, J. Sanderson, No. 59 and 440. (Herb. D. Hk. Sd.) 
Root perennial, woody. Stems numerous, 4-12 inches high or more, erect, quite 
simple, angular, ribbed and furrowed. Leaves alternate, quite sessile or shortly 
petiolate, ovate or ovato-lanceolate, acute, 1-25 inches long, 4-1 inch wide, distantly 
ciliate-dentate, glabrous, reticulated with veins. Stipules small, subulate, free. 
Peduncles axillary, as long as the leaves or shorter, 2-3-flowered, with one or more 
bracteoles at the base of each pedicel. Flowers 2-5 lines in diameter, greenish, 
with le dots outside. The outer lobes of the perianth and two of the inner, are 
rout camel or ovate-oblong ; the third inner lobe is much smaller, narrower, and 
more id than the rest. Specimens recently received from Mr. Sanderson 
differ that figured in the Thesaurus in being taller and stouter, with evidently 
petioled, longer, and comparatively narrower leaves, and somewhat larger flowers. 
g Il. MODECCA, Lam. 
Flowers wnisexual. Perianth without involucre, double ; the outer 
(or calyw) tubular-conical, campanulate or subrotate, more or less deeply 
4~—5-cleft ; the inner (or corolla) of 4-5, ovate, oblong, or linear petals,
