882 ILLUSTRATIONS OF POLYCOTYLEDONY. 



Fig. 3. — Seedling of P. lanceolata, with four cotyledons. 

 Fig.5. — Young seedling of P. mollis, with five cotyledons. 

 F;g.6.— Young seedling of P. nutans, with six cotyledons. 

 Fig. 7. — Seedling of P. pinifolia, with seven cotyledons (the third and fourth, 

 counting from the left, appearing foreshortened; a number of the 

 lowest foliage leaves were removed to expose the cotyledons). 

 (These seedlings were selected simply to make up a series illustrating the 

 variation in the number of cotyledons, and not primarily to illustrate the 

 cotyledonary arrangements of any particular species). 



(The figs, are nat. size, or slightly enlarged.) 



Plate xxxv. 

 Top row, Figs. 1-4 (counting from the left). 

 Four seedlings in which the epicotyls have been cut off close to the coty- 

 ledons, and the latter photographed from above. 



Fig.l. — P. linearis with 4 cotyledons, three of which are bifid or bipartite. 

 Fig. 2. — Another P. linearis with 5, one deeply bipartite (one accidentally 



cut off, indicated by the dotted lines). 

 Fig. 3. — P. pinifolia with 6. 

 Fig. 4. — P, lanceolata with 3. 



Nuytsia floribunda. 

 Middle row (counting from the left). 

 Fig.5. — Young seedling, with four cotyledons (the two nearer cotyledons 

 appearing foreshortened). This example shows the inequality of 

 the cotyledons. 

 Fig. 6.— Another young seedling with three cotyledons, showing the remains 

 of the seed carried up and still fixed on the tips of the cotyledons. 



Bottom row (counting from the left). 

 Figs. 7 -8. — Side and front views of another seedling with three cotyledons. 

 In this case the seed was buried too deeply for the cotyledons to 

 carry it up, when straightening. Two of the cotyledons have with- 

 drawn from the buried seed, the third not yet released. 



(About nat. size.) 

 Note. — The nnmbers on the blocks should be disregarded.
