130 — CYRILLACEAE 
Androecium of 5 or 10 stamens, those opposite the petals shorter. Filaments 
flattened, distinct. Anthers 2-celled, opening lengthwise. Disk annular, cup- 
like or cylindric. Gynoecium a single pistil. Ovary 2-5-angled, 2—5-celled. 
Style commonly wanting. Stigma 2—5-lobed. Ovules 1 or 4 in each cavity, an- 
atropous, pendulous. Fruit small, crustaceous or spongy, dehiscent or indehis- 
cent, sometimes winged. Seeds often solitary in each cavity, elongated, with a 
soft or somewhat mucous testa which merges into the fleshy endosperm. Em- 
bryo cylindric, axile. 
Racemes lateral: sepals 5, equal: petals contorted, acute: stamens 5: ovary 2-celled : ovules 2-3: fruit 
dehiscent, not winged. 1. CYRILLA. 
Racemes terminal: sepals 5-8, unequal: petals imbricated, obtuse: stamens 10: ovary 
3-4-celled : ovule 1: fruit indehiscent, winged. 2. CLIFTONIA.

em. long: pedicels 1-2 mm. long, commonly surpassing the subulate bracts : sepals trian- 
gular, 1 mm. long: corolla white, 3-4 mm. broad : petals narrowly elliptic-ovate, 2.5 mm. 
long, obtuse, thickened at the base and above the midrib: stamens included : capsule sub- 
globose, 1.5-2 mm. long, slightly granular. 
In swamps and streams, Florida and Louisiana. Spring. 
2. Cyrilla racemiflóra L. A much branched glabrous shrub or small tree reaching &

2-10 cm. long, obtuse, acute or acuminate, more or less strongly reticulated, lustrous 
above, dull and paler beneath : racemes slender, 8-15 cm. long: pedicels ascending or 
finally spreading, sometimes surpassed by their subulate bracts: sepals ovate or ovate- 
lanceolate, 1 mm. long, acute: corolla white, 4-5 mm. broad : petals lanceolate or oblong- 
lanceolate, 2-2.5 mm. long, acute: capsule ovoid, about 2.5 mm. long, obtuse, minutely 
granular: seeds narrowly ovoid. 
In swamps and along streams, Virginia to Florida and Texas. Spring and early summer. 
2. CLIFTONIA Gaertn. 
Glabrous shrubs or small trees, with a dark bark. Stems often contorted. Leaves 
alternate : blades leathery, mostly broadest above the middle. Flowers in terminal racemes. 
Pedicels drooping. Sepals 5-8, united at the base, unequal. Petals 5-8, narrowed into 
short claws, hooded at the apex, obtuse. Stamens 10, inserted at the base of the petals : 
filaments flattened below. Disk cup-like. Ovary elongated, 3-4-celled : stigma 3-4-lobed. 
Ovules solitary in each cavity. Fruit indehiscent, the angles developing 3-4 wings.

1. Cliftonia monophylla (Lam.) Britton. An evergreen shrub or small tree, reach- 
ing a height of 6 m. with a trunk diameter of 0.5 m., the trunk clothed with a dark, 
slightly scaly bark. Leaf-blades leathery, narrowly-elliptic or elliptic-oblanceolate, 
em. long, lustrous above, paler beneath, obtuse or acutish, entire, sessile: racemes 2-6 cm.
