Ipomoea triloba L.
Bejuco herbáceo, voluble o rastrero, de 2-3 m de largo, con poco látex lechoso. Tallos verdes, cilíndricos, lisos, delgados, puberulentos. Hojas alternas; láminas simples, 3-6 (9) × 3-5 (6.5) cm, ovadas a sub-circulares, usualmente 3-5-lobadas, cartáceas, el ápice mucronato, agudo o emarginado, la base cordiforme o sagitada, los márgenes lisos, levemente revolutos; haz con diminutos pelos sobre las venas; envés glabro con la nervación prominente; pecíolos glabros, algo sulcados, 2-4 cm de largo, con dos depresiones glandulosas donde se une a la lámina. Flores en cimas dicasiales simples o compuestas, axilares; pedúnculos más largo que los pecíolos, cuadrangulares, pubescentes, tuberculados. Cáliz verde, no acrescente, los sépalos pelosos, subiguales, ca. 8 mm de largo, ovados a oblanceolados, de ápice acuminado o agudo; corola violeta rosado o lavanda, usualmente rojiza en la base del centro, infundibuliforme o campanulada, 1.4-1.6 cm de largo, el limbo ca. 1 cm de diámetro; estambres sagitados, blancos, dos de ellos más cortos, no exertos; estigmas globosos, blancos, no exertos. Cápsula depreso-globosa, marrón, ca. 8 mm de diámetro, pelosa, con el estilo persistente; semillas 4 por fruto, 3-5 mm de largo, glabras, marrón obscuro a negras.
Fenología: Florece y fructifica todo el año.
Estatus: Nativa, muy común.
Comentario: En ausencia de la corola, esta especie puede confundirse con I. tiliacea en individuos con hojas relativamente grandes y no lobadas. Sin embargo, I. triloba se distingue por tener sépalos pelosos, mientras que los de I. tiliacea son glabros.

Ipomoea krugii Urb. is known only from the type collection made by Leopoldo Krug (no. 776) in Mayagüez between 1868 and 1876. The type collection of this species, like its illustration (Krug, Flora Portoricensis icones, Fig. 128) were deposited in the Botanical Museum of Berlin, but were destroyed during the Second World War. Today, the only surviving material of this species is a photograph of the illustration (distributed by the Field Museum in Chicago). The description of this species agrees in numerous aspects with Ipomoea triloba and, since the presumed species has not been collected for more than a century, it is possible that it represents a teratological collection of I. triloba with white flowers or some other ornamental species that has not become naturalized in Puerto Rico.
Flowering and fruiting: September-March
Ipomoea triloba L., Sp. Pl. 161. 1753.
Herbaceous vine, twining or creeping, 2-3 m in length, with scarce milky latex. Stems green, cylindrical, smooth, slender, puberulous. Leaves alternate; blades simple, 3-6 (9) × 3-5 (6.5) cm, ovate to subcircular, usually 3-5-lobed, chartaceous, the apex mucronate, acute, or emarginate, the base cordiform or sagittate, the margins smooth, slightly revolute; upper surface with minute hairs on the veins; lower surface glabrous, with prominent venation; petioles glabrous, somewhat sulcate, 2-4 cm long, with two glandular depressions where they join the blade. Flowers in simple or compound dichasial cymes, axillary; peduncles longer than the petioles, quadrangular, pubescent, tuberculate. Calyx green, not accrescent, the sepals pilose, subequal, ca. 8 mm long, ovate to oblanceolate, the apex acuminate or acute; corolla violet-pink or lavender, usually reddish at the base in the center, infundibuliform or campanulate, 1.4-1.6 cm long, the limb ca. 1 cm in diameter; stamens sagittate, white, two of them shorter, not exserted; stigmas globose, white, not exserted. Capsule depressed-globose, brown, ca. 8 mm in diameter, pilose, with the style persistent; seeds 4 per fruit, 3-5 mm long, glabrous, dark brown to black.
Phenology: Flowering and fruiting throughout the year.
Status: Native, very common.
Commentary: In the absence of the corolla, this species can be confused with I. tiliacea in individuals with relatively large and unlobed leaves. Nevertheless, I. triloba is distinguished by having pilose sepals, while those of I. tiliacea are glabrous.

Ipomoea triloba is a species of Ipomoea morning glory known by several common names, including littlebell and Aiea morning glory. It is native to the tropical Americas, but it is widespread in warm areas of the world, where it is an introduced species and often a noxious weed. This is a fast-growing, vining, annual herb producing long, thin stems with ivy-like, petioled, heart-shaped leaves 3 to 6 centimeters long. The leaves sometimes, but not always, have three lobes. The vines produce tubular bell-shaped flowers, each about two centimeters long. They are quite variable in color, in shades of pink, red or lavender, with or without white markings.
