1. Ibervillea Lindheimeri (A. Gray) Greene. Stems slender, climbing or trailing, 
2-4 m. long, sparingly branched : leaf-blades thinnish, more or less warty-papillose, 3-5-

3. Ibervillea tenélla (Naud.) Small. Stems slender, climbing or creeping, 1-2 m. 
long, obtusely angled : leaf-blades thickish or fleshy, usually 3-4 cm. in diameter, 3-parted, 
often warty, the terminal lobe coarsely toothed or again lobed, usually acute, more or less 
cuneate, the lateral lobes usually again 2-lobed, the lobes toothed ; petioles about 1 em. 
long: hypanthium glabrous, campanulate, 3-4 mm. long: sepals ovate, 1-1.5 mm. long, 
acute : corolla yellow, broadly ovate, acutish, striped with green without, glandular-pilose 
within : berries globose, 2.5-4 cm. long : seeds oval, 6-8 mm. long, with 2 horns at the base, 
the faces swollen. [Sicydium tenellum Naud.] 
In valleys, Texas. Spring and summer. 
4. Ibervillea tenuisécta (A. Gray) Small. Stems very slender, prostrate or climb- 
ing, several meters long, often diffusely branched : leaf-blades thickish, 1-4 cm. in diame- 
ter, 3-5-parted, the lobes deeply cleft or pinnatifid, the ultimate divisions linear or nearly 
so, acute or rarely obtuse ; petioles 0.5-1 cm. long: hypanthium glabrous, campanulate, 
3-4 mm. long: sepals triangular or ovate-triangular : corolla yellow : berries globose, 1- 
1.5 cm. in diameter, becoming scarlet : seeds obovoid, 5-6 mm. long, thick-margined, with 
two blunt horns at the base, the faces much swollen and transversely wrinkled. [Sicydium 
Lindheimeri var. tenuisectum A. Gray.] 
In valleys, Texas and New Mexico to Mexico. Spring to fall. 
3. MOMORDICA L. 
Annual or perennial herbs, with climbing stems and simple tendrils. Leaf-blades en- 
tire, lobed or pedately compound. Flowers monoecious or dioecious, the staminate soli- 
tary or panicled: hypanthium short-campanulate: sepals 5: corolla rotate, 5-lobed, 
white or yellow: stamens 3, or very rarely 2; filaments short, distinct ; anthers at e 
slightly cohering, finally distinct. Pistillate flowers solitary : calyx and corolla like those 
of the staminate flowers: staminodia wanting or gland-like. Ovary 1-celled, with 3 pla- 
centae: style slender: stigmas 3. Ovules numerous, horizontal. Berry elongated, rarely 
3-valved. Seeds usually numerous, flat or swollen, smooth or sculptured. BArsAM APPLE. 
Leaf-blades with acute or obtuse teeth : scale at the middle or base of the staminate pese n nti. 
Leaf-blades'with acuminate teeth : scale toothed at the apex of the staminate peduncle. 2. M. Balsamina. 
1. Momordica Charántia L. Stems often high-climbing, at least 1-2 m. long, oF 
longer, much branched, angled : leaf-blades thinnish, 4-12 cm. in diameter, ery a 
lobed, the lobes obovate or oblanceolate, coarsely toothed or slightly again lobed, Ph d 
or lobes acute or obtuse, the sinuses usually rounded ; petioles 3-5 cm. long, dl da^ 3 
glabrate, angled: peduncles bearing entire ovate-cordate scales at the base or middle i anh 
panthium usually puberulent, campanulate : sepals oval or oval-ovate, 3-4.5 d dod
