280 COENACEAE. 



Family 3. CORNACEAE Link. 

 Dogwood Family, 



Shrubs or trees, with simple opposite, verticillate or alternate, usually 

 entire leaves, and regular flowers in cymes, heads or rarely solitary. Calyx- 

 tube adnate to the ovary, its limb 4-5-dentate, or none. Petals generally 

 4 or 5, sometimes wanting, valvate or imbricate, spreading, inserted at the 

 base of the epigynous disk. Stamens as many as the petals or more 

 numerous, inserted wdth them; filaments subulate or flat. Ovary inferior, 

 1-2-celled in our species; style 1, short or elongated; ovules 1 in each 

 cavity, pendulous, anatropous. Fruit a drupe. Seeds oblong; embryo 

 nearly as long as the endosperm; cotyledons foliaceous. About 16 genera 

 and 85 species, most abundant in the northern hemisphere. 



My only knowledge of the existence of any of this family in Bermuda, is 

 the record by Lefroy of the introduction, prior to 1876, of a species of a 

 North American Cornus at Mount Langton, which appeared to thrive and 

 which was referred to in 1901 by H. B. Small as Cornus stricta Lam., and by 

 the same author, the planting there of Benthamia fragifera Lindley, Hima- 

 layan, which did not appear to flourish. 



Series 2. GAMOPETALAE. 



Petals partly or wholly united, rarely separate or "wanting. 



The coherence of the petals is sometimes slight or they are quite 

 separate, as in some Ericaceae, Primulaceae, Asclepiadaceae, Ole- 

 aceae and Cucurbitaceae. From this condition the coherence varies 

 through all stages to the tubular or funnelform corollas of some 

 Convolvulaceae, Caprifoliaceae and Compositae. 



t Ovary superior. 



Stamens mostly free from the corolla, or adnate merely 

 to its base, as many as the lobes and alternate with 



them, or twice as many. Order 1. Ericales. 



Stamens borne on the corolla, as many as its lobes and 

 opposite them, or twice as many, or more. 

 Herbs, shrubs or trees ; ovary 1-celled. Order 2. Primulales. 



Shrubs or trees : ovary several-celled. Order 3. Ebexales. 



Stamens borne on the corolla, as many as its lobes or 

 fewer, and alternate with, them (in our species of 

 Fraxinus and Forestiera of the Oleaceae there is 

 no corolla). 

 Corolla not scarious. nerved. 



Ovaries 2, distinct (except in some Loganiaceae, 

 and in Gentianaceae in which the ovary is 

 compound with 2 cavities or rarely more, or 

 with 1 cavity and 2 placentae : flowers regular ; 

 stamens mostlv adnate to only the lower part 



of the corolla ; leaves mostly opposite. Order 4. Gextianales, 



Ovary 1, compound (2-divided in Dichondra; in 

 Boraginaceae and Lamiaceae mostly deeply 

 4-lobed around the style) ; flowers regular or 

 irregular ; stamens mostly adnate to the middle 

 of the corolla-tube or beyond ; leaves opposite 



or alternate. Order 5. Polemoniales. 



Corolla scarious, nerveless. Order 6. Plantaginales. 



tt Ovary inferior. 

 Anthers distinct. 



Stamens as many as the cojrol la -lobes and alternate 

 with them or twice as many ; ovary compound, 

 with 1 ovule or more in each cavity ; leaves oppo- 

 site or verticillate. Order 7. Ribiales.
