beneath, 3.5 to 12.5 cm. long: flowers in loose, mostly broad, often paniculate cymes: 
calyx-teeth small: fruit white on red stalks: stone globular or nearly so, mostly not 
at all ridged, but little broader than high, about 4 mm. in diameter.—Var. DRUMMON- 
pu Coult. & Evans has harsher and usually more crowded leaves and a smaller 
stone. (C. Drummondii C. A. Meyer.)—An eastern species, extending to central 
Texas, where the variety is the common form. 
4. C. candidissima Marsh. Erect shrub 25 to 45 dm. high, with smooth mostly 
grayish branches: leaves lanceolate to ovate, acuminate, acutish at base, minutely 
appressed pubescent or glabrous on either or both sides, the lower surface from whit- 
ish to scarcely paler than the upper, 3.5 to 10 cm. long: flowers in numerous loose 
paniculate cymes: calyx-teeth from small to prominent: anthers more or less blue 
along the connective: ‘fruit white to pale blue: stone small, nearly globular, not fur- 
rowed or very slightly so, 3t05 mm. in diameter. (C. stricta Lam. C. paniculata 
L’Her.)—An Atlantic species extending into Texas. 
2. NYSSA L. (TUPELO. PEPPERIDGE. SOUR-GUM TREE.) 
Trees with entire or angulate-toothed leaves which are alternate but 
mostly crowded at the ends of the branchlets, greenish diceciously 
polygamous flowers clustered or rarely solitary at the summit of ax- 
illary peduncles and appearing with the leaves, and an ovoid or oblong 
drupe with a bony and grooved or even winged 1-celled 1-seeded stone. 
The staminate flowers are numerous in a simple or compound dense 
cluster of fascicles, with a small 5 parted calyx, petals as in the pistil- 
late flowers or none, 5 to 12 (mostly 10) stamens inserted on the ‘outside 
of a convex disk with slender filaments and short anthers, and no 
pistil. The pistillate flowers are solitary or 2 to 8, sessile in a bracted 
cluster and much larger than the staminate flowers, with a very short 
repand-truneate or minutely 5-toothed limb, very small and fleshy 
deciduous petals (or none), 5 to 10 stamens with perfect or imperfect 
anthers, and an elongated revolute style stigmatic down one side. 
1. N. aquatica L. A tree becoming 15 to 36m. high: leaves from linear-oblong or 
lanceolate to oval or obovate, acute or acuminate, entire, smooth and shining above 
(when old), more or Jess hairy along the veins beneath, or almost woolly when young, 
5 to 17.5 cm. long: Staminate flowers numerous in loose or somewhat dense clus- 
ters; pistillate flowers 2 to 14 at the apex of a more or less elongated peduncle, 
mostly developing 1 to 3 fruits: fruit ovoid, acid, bluish-black, 8 to 13 mm. long: 
stone ovoid, smooth or scarcely ridged. (N. sylvatica Marsh. N. multiflora Wang.)— 
An eastern species extending into Texas to the valley of the Brazos, 
2. N. uniflora Wang. A large tree 15 to 30 nm. high: leaves long-petioled, ovate 
or oblong, mostly obtuse or even cordate at base, acute or acuminate, entire or angu- 
late-toothed, becoming smooth above, pale and downy pubescent beneath (especially 
when young), 7.5 to 25 cm. long: staminate flowers numerous, in rather dense clus- 
ters; pistillate flowers solitary on slender elongated peduncles: fruit olive-shaped, 
becoming dark blue, 16 to30 mm. long: stone narrowly obovate, flattened, and with 
prominent acute almost winged ridges.—Extending from the Gulf States to the valley 
of the Neches, and possibly within our range, 
3. GARRYA Dougl. 
Evergreen shrubs, with 4-angled branchlets, opposite entire coriaceous 
‘leaves with the short petioles connate at base, dicecious flowers in ax- 
illary aments, no petals, and a blue or purple fruit,—The staminate
