Water Gum 737 ous for their autumnal coloration. The flowers, appearing with the leaves, are small, greenish, polygamo-dioecious, in small clusters, short racemes or sometimes soUtary on slender axillary peduncles. The staminate flowers are numerous, their calyx cup-shaped, 5-lobed; petals 5, small, fleshy, rarely none; stamens, 5 to many, borne on an entire or lobed disk. The pistillate flowers, 2 to many or solitary, are on axillary peduncles; calyx 5-toothed; petals small or minute; stamens several, usually abortive; ovary sessile, i- to 2-celled, with a solitary ovule; style slender, recurved, its apex stigmatic. The fruits are fleshy drupes, solitary or clustered, ovoid or oval; the stone is large, bony, more or less ridged; seed usually i, com- pletely filling the cavity; embryo in abundant fleshy endosperm. The name apphed to these trees by Linnaeus is that of a water nymph, on ac- count of the aquatic habit of the type species, N. aquatica. One additional species, a shrub, Nyssa acuminata Small, occurs in the southern Atlantic States. Our arborescent species are: Pistillate flowers 2 to several; drupe i to cm. long; stone ridged. Stone much flattened, prominently ridged. i. N. biflora. Stone little flattened, indistinctly ridged. 2. N. sylvatica. Pistillate flower i; drupe 3 to 4 cm. long; stone sharp edged or winged. Leaves acuminate; pedicels longer than the blue or purple drupe. 3. N. aquatica. Leaves blimt, minutely tipped; pedicels shorter than the red drupe. 4. N. Ogeche. I. WATER GUM—Nyssa biflora Walter The Water gum, also called the Black gum, and Water tupelo, inhabits swamps and the margins of ponds from New Jersey to Florida and Louisiana, where it attains a maximum height of 40 meters, with a trunk diameter of 2 m. The trunk gradually tapers from a swollen base; when
