412 TETRAGONIACEAE 
* 
with a green midnerve and a reticulation of green secondary nerves : capsule subglobose, 
1.5-2 mm. in diameter : seeds finely reticulated. 
On wet or dry plains or prairies, Texas to California and Mexico. Also widely distributed in tem- 
perate and tropical regions. Spring to fall. 
2. Mollugo verticillàta L. Foliage glabrous. Stems branched at the base, the 
branches slender, spreading radially, prostrate, 4-30 cm. long, forking: leaves in apparent 
whorls of 4-8 ; blades unequal, narrowly or broadly spatulate, 1-3 cm. long, rounded or 
acute at the apex, entire, short-petioled : pedicels 3-8 mm. long, reflexed in fruit : sepals 
oblong, 2 mm. long, obtuse, with hyaline margins: stamens 3, shorter than the sepals : 
styles 3, the tips recurved : capsule oblong or oval, 4-5 mm. long, surpassing the sepals : 
seeds red, 0.6 mm. broad, shining. 
In waste places and cultivated grounds, New Brunswick, Ontario and North Dakota to Florida. 
Texas and Mexico. Widely distributed. Spring to fall. CARPET-WEED. 
2. GLINUS L. 
Annual herbs, with forking branches and usually pubescent foliage. Leaves basal and 
cauline, whorled, often fleshy : blades unequal: stipules hyaline. Flowers perfect, sessile, 
clustered. Sepals 5, with hyaline borders, tomentose without. Stamens mostly 5-10: 
filaments filiform: anthers 2-celled. Ovary 3-5-celled, superior: styles very short or 
none: stigmas sometimes sessile. Ovules numerous. Capsule often included in the calyx: 
3-5-valved. Seeds numerous, strophiolate, with elongated coiled funiculi: aril conspicuous. 
1. Glinus lotoides Loefl. Foliage villous-pilose, especially when young. Stems 
stout, more or less diffusely branched at the base, the branches radially spreading, 0.5-3 
dm. long, forking: leaves apparently whorled ; blades very unequal, suborbicular, often 
broader than long, rounded or apiculate ; petioles shorter than the blades: flowers 
sessile or nearly so: sepals linear-lanceolate, 3-4 mm. long, acuminate, pubescent, with 
hyaline margins: stamens 5: stigmas sessile: capsule oblong-ovoid, 3 mm. long, shorter 
than the sepals : seeds dull red, 0.6 mm. broad, granular. 
In waste places and cultivated soil, the Indian Territory and Arkansas. Summer. Naturalized 
from Europe.—A related species G. Cambessidésii Fenzl., with a less robust habit, smaller flowers, 3-5 
stamens and smooth seeds. occurring from Mexico and lower California to South America and in Cuba, 
has apparently been collected in Texas. 
3. CYPSELEA Turp. 
Annual or probably perennial, rather diminutive herbs, with elongated roots. Leaves 
opposite, those of each pair unequal, with laciniate scarious stipules. Flowers axillary. 
Sepals 4-5, erect, green, unequal, unappendaged. Hypanthium campanulate. Stamens 
1-3, alternate with the sepals: filaments shorter than the calyx. Ovary 2-celled, or 
1-celled by suppression, superior: styles usually 2, erect. Ovules numerous. Capsule 
circumscissile. Seeds minute, estrophiolate, becoming detached from the straight funiculi 
which remain attached to the central placenta. 
1. Cypselea humifüsa Turp. Low, glabrous. Stems densely branched at the base, 
the branches prostrate, forming small mats 2-10 cm. broad : leaf-blades oblong to oval, 3-9 
mm. long, obtuse, pellucid-punctate, on short petioles with dilated hyaline bases ; stipules 
becoming lacerate: flowers greenish, axillary, short-pedicelled : sepals 5, ovate: stamens 
3 or sometimes 1 or 2, alternate with the sepals: capsule subglobose, 1.5-2 mm. in diame- 
ter, apiculate. 
In sandy pine lands, peninsular Florida and California. Introduced from the West Indies. 
4. TRIÁNTHEMA L. 
Annual or perennial herbs or shrubby plants, with a spreading habit. Stem com- 
monly branched at the base. Leaves opposite, those of each pair unequal, with stipules 
Flowers axillary. Sepals 5, petal-like, with horn-like appendages on the back below the 
apex. Stamens 5-6, or sometimes 10: filaments alternating with sepals when of the same 
number. Ovary 2-celled, or 1-celled by suppression, superior, truncate : styles usually 2, 
sometimes eccentric. Ovules few. Capsule turbinate to cylindric, tardily circumscissile, 
often leathery or corky above, with usually 2 marginal crests partly or wholly surrounding 
the oblique concave top. 
1. Trianthema Portulacástrum L. Perennial, fleshy, sometimes sparingly pubes- 
cent. Stems diffusely branched at the base, the branches often prostrate, 5-10 dm. long;
