with yellow, pink, red, or purple flowers, the tips of the spikes variously 
fasciated. It has not been found as a spontaneous plant here. Tropics

3. GOMPHRENA Linnaeus 
Erect, branched, hirsute or villous herbs, the nodes usually thickened. 
Leaves opposite. Flowers in peduncled heads, white or purple. Sepals 5, 
lanceolate, acuminate. Stamens 5; filaments united into a long tube, 
cleft at the top, usually without staminodes. Ovary 1-celled, 1-ovuled; 
style short or long; stigmas 2. Utricle compressed, indehiscent. (From 
the Greek name of an allied plant.) 
Species about 70 in South America and Australia, the following now 
cosmopolitan in the tropics. 
1. G. GLoBosA L. Botoncillo (Sp.-Fil.). 
An erect, branched, pubescent annual, the branches more or less 
thickened and often purplish at the nodes. Leaves petioled, oblong, acute 
or obtuse, 7 to 11 cm long. Flowers numerous, densely crowded in globose 
heads, the heads white, pink, or purple, solitary, peduncled, 1.5 to 2 cm in 
diameter, subtended by 2 leafy bracts. Bracteoles 8 to 10 mm long, en- 
closing the flowers, lateral, keeled. Sepals pubescent. (FI. Filip. pl. 68.) 
Commonly cultivated for ornamental purposes, occasionally spontaneous, 
fl. all the year. Undoubtedly a native of tropical America, now wild or 
cultivated in most warm and tropical countries. 
4. ALTERNANTHERA Forskal 
Prostrate or spreading branched herbs with opposite leaves. Flowers 
small, white, in axillary, sessile or subsessile, solitary or clustered heads. 
Sepals unequal, three flattened, the inner and lateral two concave. Stamens 
2 to 5, filaments short, connate into a short cup, with or without alter- 
nating staminodes; anthers 1-celled. Ovary 1-celled, 1l-ovuled; stigma 
subsessile. Utricle compressed, ovoid to obcordate, margins often winged 
or thickened. (Latin “alternate” and “anther.”’) 
Species about 16 in most tropical and subtropical countries, 3 or 4 in 
the Philippines. 
1. Glabrous or nearly so. 
2. Spreading; leaves elliptic-lanceolate to linear-lanceolate, green. 
1. A. sessilis 
2. Usually erect; leaves spatulate to oblong-obovate; cultivated plants, 
the leaves variegated with red................c:::c:-s--2000000000 2. A. versicolor

1. A. sesstmnis (L.) R. Br. : 
_A spreading or prostrate much-branched herb, the branches up to 60 
em long, the ultimate ones with 2 lines of hairs on the internodes, the

to linear-lanceolate, acute or obtuse, sessile, obscurely toothed. Heads 
axillary, solitary or clustered, globose to oblong, white, 5 to 7 mm long. 
Sepals lanceolate, acute or acuminate, 2 to 2.6 mm long. Stamens 2 or 3. 
Utricle broadly obcordate. 
In open waste places, common, fl. all the year; throughout the Philippines.
