202 ON SEEDLINGS 



Leaves simple, entire, cauline, alternate, exstipulate, shortly 

 petiolate, alternately penninerved, with the nerves uniting at their 

 apex and forming a continuous intramarginal line, glabrous, coria- 

 ceous, deep green above, pale beneath, shining on both surfaces ; 

 petioles short, channelled above, terete on the back. 



No. 1. Lanceolate-oblong, cuspidately acute. 



No. 2. Similar, larger. 



Nos. 3-6. Lanceolate-linear, acute, or acuminate, gradually 

 longer. 



Pittosporum parviflorum, Putterl. 



Hypocotyl glabrous. 



Cotyledonstwo to three, lanceolate, obtuse, glabrous, shortly petio- 

 late, obscurely penninerved, reticulate, foliaceous, rather persistent. 



Stem terete, erect, soon becoming woody. 



First three leaves obovate-lanceolate, entire, small, cuneate at 

 the base. 



Pittosporum crassifolium (?), Banks et Sol. (fig. 193). 



Hypocotyl 3-4 cm. long, a little over 1 mm. thick, woody, covered 

 to the very base with a purplish pubescence (like Gynura auran- 

 tiaca). 



Cotyledons two, three, or four, opposite or whorled, nearly equal, 

 shortly petioled, 1-5-2 cm. long, about 1 cm. broad, nearly flat, oblan- 

 ceolate, produced at the base, with a short blunt mucro at the 

 obtuse, slightly recurved apex, penninerved, with sunk midrib and 

 obscurely reticulate veins, hairy on both sides, ciliated on margin 

 and petiole, light green, rather persistent. 



Stem like the hypocotyl, but darker and tomentose. 



Leaves penninerved with the branches ascending, branching or 

 incurved towards the tip, reticulate, with the principal nerves sunk 

 on the upper surface, glabrous above, pubescent or tomentose on the 

 margin, tomentose beneath with a prominent venation ; petioles 

 short, semiterete. 



Nos. 1 and 2. Eotund-obovate, cuneate at the base. 



Nos. 8 and 4. Obovate, obtuse, gradually becoming larger up- 

 wards. 



NOTE. I was at first disposed to think that the number of coty- 

 ledons in this species might be an accidental variation. There are 

 other cases where occasionally three cotyledons occur instead of two. 

 In Acer Pseudo-Platanus, for instance, this is not infrequently the 

 case, and I have observed that such specimens occur especially often 

 in the produce of particular trees.
