334 ON SEEDLINGS 



Cotyledons stalked, tripartite ; segments 5-6 cm. long, 1-1-25 cm. 

 broad, the middle one lanceolate, lateral ones oblique-lanceolate, 

 long-acuminate, entire, with slightly undulate margin, distinct mid- 

 rib, and alternate, incurved nerves and veins, quite glabrous, light 

 shining green, somewhat persistent. 



Stem terete, shaUowly ridged and furrowed, covered with a dense 

 patent pubescence, pale green, becoming woody ; 1st internode 

 2 cm. long, T5 mm. thick ; 2nd internode 6 mm. long. 



Leaves cauline, alternate, exstipulate, petiolate ; petiole terete, 

 slightly channelled above, tapering upwards, ascending, densely 

 pubescent, 2*7 cm. long ; lamina ovate, acuminate, or almost oval 

 with an acuminate, subacute point, serrate, penninerved, with 

 alternate ascending nerves ultimately curving forwards, coarsely 

 hairy and pale green on both surfaces, shining above, horizontal.

Fruit and Seed. The carpels vary from three to five, and 

 are united into an ovary of as many cells. The most frequent 

 number of ovules is two, and they are collateral or superposed, 

 pendulous or ascending, with a ventral raphe and a superior 

 micropyle. Exceptions to the above characters occur in 

 Elutheria, which has a one- or imperfectly four-celled ovary ; 

 and in Chisocheton, which has one ovule in each cell ; the 

 same thing sometimes occurs in Aglaia, Milnea, Amoora, and 

 Guarea. The ovary of Turreea varies in different species with 

 from five to twenty loculi. Numerous ovules occur in each 

 cell of the ovaries of the species belonging to the tribes 

 Swieteniese and Cedreleae. The fruit is baccate, capsular, or 

 less often drupaceous. Instances of the latter occur in Melia, 

 Mallea, and Owenia. 



The seeds are albuminous or exalbuminous, varying how- 

 ever in the same genus in some cases ; the endosperm when 

 present is fleshy. The testa is drawn out into a wing in 

 Soymida, Chickrassia, Cedrela, Chloroxylon, and Flindersia. A 

 curious case occurs in Swietenia and Khaya, where the coty- 

 ledons and endosperm are closely adherent. The cotyledons are 

 fleshy and more or less flattened. They are bipartite in Milnea
