A FLORA OF MANILA
2. LAN TAN A Linnaeus
Erect or subscandent aromatic shrubs, usually prickly, pubescent or
scabrous. Leaves simple, crenate. Inflorescence axillary, the flowers in
peduncled, ovoid to oblong, short heads or spike-like heads. Calyx small,
thin, truncate or slightly toothed. Corolla-tube slender, cylindric, the lobes
4 or 5, spreading. Stamens 4, in 2 pairs, included. Ovary 2-celled, 2-
ovuled. Fruit fleshy, containing 2, hard, 1-celled pyrenes. (An ancient
name for one of the viburnums.)
Species about 40, chiefly in tropical America, a single introduced one in
the Philippines.
1. L. CAMARA L.
An erect or subscandent, somewhat hairy, aromatic shrub, when erect
usually 1 to 2 m high, when scandent twice as high. Leaves ovate, acuminate,
toothed, 5 to 9 cm long. Flowers in peduncled many-flowered heads
including the corollas 2 to 3.5 cm in diameter. Corollas pink, red, or
yellow, about 1 cm long, the limb 6 to 7 mm wide. Fruits in an ovoid,
2 cm long head, on a thickened, fleshy receptacle, the individual ones ovoid,
purple or black, fleshy, about 5 mm long. (Fl. Filip. pi. 216.)
In waste places, thickets, etc., abundant, fl. all the year; widely distributed
and thoroughly naturalized in the Philippines. A native of tropical
America, now found in most tropical countries.
3. LIPPIA Linnaeus
Prostrate herbaceous plants (in our species) with opposite toothed leaves.
Flowers small, in peduncled, solitary, axillary, dense, ovoid or cylindric
spikes, each subtended by a broad, ovate or obovate bract. Calyx small,
2-fid. Corolla-tube slender, the limb 2-lipped, spreading. Stamens 4, in 2
pairs, included. Fruit small, dry, separating into two 1-seeded pyrenes.
(in honor of A. Lippi, a French traveler.)
Species about 90, mostly American, single one in the Philippines, cer-
tainly introduced.
1. L. NODIFLORA (L.) Rich.
A creeping, minutely strigose plant, the stems 15 to 90 cm long, branched
and rooting at the nodes. Leaves nearly sessile, obovate, base wedge-shaped,
entire, the margins in the upper one-half sharply toothed, apex obtuse or
rounded, 1 to 2.5 cm long. Peduncles axillary, solitary, erect, 2 to 7 cm
long. Spikes ovoid or cylindric, very dense, 1 to 2.5 cm long, about 6 mm
in diameter. Corolla about 3 mm long, pink, the tube slender, the limb 2.5
mm wide or less, the spike flowering at the apex, as it lengthens.
Common in waste places, lawns, etc., fl. all the year; throughout the
Philippines, certainly introduced. Tropics generally, probably originating
in tropical America.
4. STACHYTARPHETA Vahl
Erect, branched, suffrutescent herbs. Leaves opposite or alternate,
toothed. Spikes terminal, elongated, slender, the bracts long or short,
bracteoles none. Flowers solitary in the axils of the bracts, half-immersed
in the rachis of the spike. Calyx narrowly cylindric, 4- or 5-toothed.
Corolla blue, the tube slender, cylindric, the limb spreading, oblique, 5-lobed.
Stamens 2, included in the tube, 2 staminodes also present. Ovary 2-celled,
