Branches erect, amooth ; leaves ovate-lanceolate, acuminate, acute at base, 

 scabrous above, hoary beneath ; ci/mes paniculate; drupes white. A hand- 

 some shrub, 10 feet high, common in low woodlands and thickets. It has 

 numerous and very branching stems, covered with a greyish bark, the shoots 

 chestnut-colored. In June it puts forth its small white flowers in numerous, 

 conical cymes or panicles, succeeded by small drupes. 



Punicled Cornel or Dogicood. 



** Flowers umbellate; involucre 4-leaved, petaloid. 



6. C. flo'rida. 



Aboreous ; leaves opposite, ovate, acuminate, entire ; flowers small, in a 

 close, cymose umbel or head, surrounded by a very large, 4-leaved, obcordate 

 involucre. A tree from 20 to 30 feet in bight, verv ornamental when in flow- 

 er. Found in woods. Fall Mt. Walpole, N. H., and thinly dispersed from 

 thence to Florida. Tiie wood is very hard and compact, covered with a rough 

 bark which is extremely bitter, and used in medicine as a tonic. The leaves, 

 whicli at flowering time are but partially expanded, are acutely ovate, nearly 

 smooth, veiny, pale underneath. The tree flowers are inconspicuous, green- 

 ish-yellow, but the involucre is very large and showy, of veiny, white, obo- 

 vale leaves, ending in a callous point, whicli is turned up or down so abruptly 

 as to give an emarginate appearance to the leaf. Flowers in May, in great 

 profusion. Drupe red. Flowering Dogicood. 



7. C. Canade'nsis. 



Herbaceous, low ; upper leaves whorled, veiny, on short petioles ; stem sim- 

 ple. A small, handsome plant, common in woods, remarkable for its large, 

 white involucre. Subterranean stems creeping, woody, root-like. The flow- 

 ering stems erect, 4 — 8 inches high, bearing 2 small stipules in the middle, 

 and a whorl of (5 leaves at the top. two of which are larger, placed a little 

 lower and opposite. An umbellate cyme of flowers arises from the centre of 

 the whorl, and with its large, siiowy involucre of 4 white leaves, might easily 

 be taken for a single flower. They are succeeded by a bunch of red berries. 

 The barren stems support a whorl of 4 equal leaves. May. Jn. 



Low Cornel or Dogwood.
