140 A FLORA OF MANILA 
surface glabrous, the lower surface often pilose, the sheaths ciliate with 
long, soft, brownish hairs, the leaves of the lateral branches often smaller 
thah those on the main stem. Flowers blue, terminal, solitary, sessile or 
nearly so. Sepals about 4 mm long. Filaments bearded. 
In damp ravines opposite Fort McKinley, fl. Oct.Nov.; not uncommon 
in the Philippines. Malay Archipelago. 
2. C. cristata (L.) Schultes f. 
A succulent, prostrate, glabrous or somewhat hairy, much branched herb, 
the stems often purplish, rooting at the lower nodes, the branches ascending, 
15 to 40 cm high. Leaves distant, ovate to ovate-oblong, sessile, fleshy, 
acute or obtuse, 3 to 5 em long. Inflorescence enclosed in a series of 
2-seriate, falcate, imbricate bracteoles, about one flower opening at a time, 
the bracteoles crowded, 1 to 1.5 cm long. Sepals lanceolate, green, hairy, 
4to5mm long. Corolla blue, 8 mm long, the filaments prominently bearded 
with blue hairs above. (FI. Filip. pl. 83.) 
In open waste places, occasional, fl. Sept._Feb.; throughout the Philip- 
pines. Tropical Africa, Asia, and Malaya. 
3. C. axillaris (L.) R. & S. 
A succulent, prostrate, somewhat branched, glabrous plant, the stems 
about 5 mm thick, 20 to 40 cm long, rooting at the nodes. Leaves lanceolate, 
4 to 11 cm long, 6 to 12 mm wide. Flowers several in each leaf-axil, only 
one opening at a time, the bracteoles small, not imbricating. Calyx pale- 
greenish. Corolla purplish, the petals long-clawed, limb 5 to 6 mm long. 
In open waste places, cultivated lands, etc., fl. all the year; throughout 
the Philippines. India to China, Malaya, and Australia. 
5. ZEBRINA Schnizlein 
Decumbent, spreading or pendulous, branched herbs, slightly pilose. 
Leaves oblong to ovate, variegated, base sheating. Flowers several to 
many, more or less crowded between the two terminal somewhat bract-like 
leaves. Calyx of 3 sepals connate into a cylindric tube. Petals 3, connate 
into a slender tube longer than the calyx, the limbs spreading, ovate to 
lanceolate. Stamens 6, equal, inserted on the throat of the corolla-tube. 
Capsule 3-celled, on a short recurved peduncle, the seeds 1 or 2 in each 
cell. (From the striped leaves.) 
Species 2 or 3 in Texas and Mexico, 1 widely cultivated, introduced in 
the Philippines. 
1. Z. PENDULA Schnizl. Wandering Jew. 
Stems rather slender, branched, spreading or pendulous, up to 1 m long, 
glabrous or somewhat hairy on one side. Leaves elliptic-ovate to oblong- 
ovate, acute, 3 to 9 cm long, the upper surface with grayish-green and 
purple longitudinal stripes, the lower surface purple, base sheathing, villous. 
Flowers glomerate between the 2 terminal, somewhat bract-like leaves. 
Calyx about 6 mm long. Corolla-tube very slender, nearly 1 cm long, the 
lobes oblong, pink-purple, 6 to 7 mm long. 
Cultivated, fl. at intervals; occasionally escaped from cultivation in Ma- 
nila, and naturalized in some provinces. A native of Mexico, now widely 
cultivated, but apparently of comparatively recent introduction in the 
Philippines.
