GARDENER’S AND BOTANIST’S DICTIONARY. 
DICOTYLEDONEZ. 
GRAND DIVISIONS. 
Grand piviston I. VASCULA‘RES, (from vas, a ves- 
sel; plants furnished with spiral vessels) or COTY- 
LEDO'NEA, (korvAndwy, cotyledon, a seed leaf; plants 
furnished with seed leaves.)—Plants with cellular tissue 
(f. 1. 1. b.), woody fibre and spiral vessels (a a), and fur- 
nished with true leaves (f. 1. 3. 8. 7.). The flowers usually 
distinct and symmetrical (f. 2.). Embryo furnished with 
cotyledons (f. 1. 4. 5. 10. a@.), and inclosed within a 
seed-cover. This division contains all the classes of Lin- 
nus, Cryptogamia excepted. 
Grand pivision II. CELLULA‘RES, (cellula, a lit- 
tle cell; plants with cellular tissue only,) on ACOTY- 
LEDO'NEZ, (a. privative, corvAndwyr, cotyledon; plants 
without cotyledons.)—Plants with cellular tissue only 
(f. 1. 11, 12.). Embryo destitute of cotyledons. Parts 
of fructification hidden (f. 1. 14. 13. a.). This grand di- 
vision only contains the class Cryptogamia of Linnzus. 
GRAND DIVISION I. 
VASCULA'RES or COTYLEDO'NEZ. 
CLASSES. 
Crass I. DICOTYLEDONES, (tc, dis, two; KorvAncwr, 
cotyledon ; plants furnished with two cotyledons) or EXO- 
GENE (ew, exo, without; yevvaw, gennao, to bring forth ; 
stem increasing by external layers). D. C. syst. 1. p. 123. 
prod. 1. p. 1. 
Stem increasing by external layers; with an evident distinc- 
tion between bark and wood (f. 1. 2. a, b.). Leaves traversed 
by branch veins (f. 1. 3.). Parts of flower generally disposed 
in a quinary number (f. 2. 2.). Embryo with 2 opposite coty- 
ledons (f. 1. 4. a.), or when more they are disposed in a whorl 
(f. 1. 5. a.). Plumule in the centre of their point of junction 
VOL. 1. 
(f. 1. 4. b. and 5. b.): the inferior end of the embryo itself 
elongated into a radicle, and not containing any secondary ra- 
dicles in its substance (f. 1. 4. c. and 5. c.). 
Crass II. MONOCOTYLEDO'NEA, (povoc, monos, one; 
kotrvAnowy, cotyledon, plants furnished with 1 cotyledon) or 
ENDOGE'NEE (evéoy, endon, within; yevvaw, gennao, to 
bring forth ; stem increasing by internal layers.) 
Stem increasing by internal layers with no evident distinction 
between bark and wood, but are mixed together (f. 1. 6.). 
Leaves traversed by simple veins (f. 1. 7. 8.) usually with no 
articulation between the leaves and the stem, while in Dico- 
tyledonez the leaves are always joined with the stem, from 
which they fall off, leaving a scar behind. Embryo fur- 
nished with 1 cotyledon (f. 1. 10. a.), or if 2, they are alter- 
nate (f. 1. 9. a.); the inferior end elongated into a radicle or 
radicles (f. 1.10. b. & 9. b.). Plumule usually inclosed in 
the body of the embryo. 
CLASS I. 
DICOTYLEDO'NEZ or EXOGENÆ. 
Synopsis of the Subclasses, deduced from the organs of fructi- 
fication. 
1. Perigone double. (f. 2.3. and 4. b.) 
Subclass I. THALAMIFLORÆ. (f. 2. 1.) 
Petals many, distinct ; and are, as well as the stamens, inserted 
in the receptacle (a).
