ON SEEDLINGS 



Sapindus insequalis, DC. (fig. 251). 



Hypocotyl undeveloped. 



Cotyledons large and fleshy, filling the seed, which they do not 

 leave in germination; petioles thick, 

 fleshy, colourless, semiterete, pushed 

 out of the seed or elongated to conveni- 

 ence the radicle and plumule. 



Stem erect, terete, green, hairy, soon 

 becoming glabrous, ultimately woody ; 

 1st internode 2-5 cm. ; 2nd -95 cm. ; 

 3rd 2 cm. ; 4th -95 cm. ; 5th 2'1 cm. ; 

 6th '55 cm. ; 7th '75 cm. 



Leaves cauline, alternate, exstipulate, 

 petiolate, irregularly and alternately pen- 

 ninerved with ascending nerves, thinly 

 hairy on both sides, soon becoming gla- 

 brous above, pale green and shining 

 above ; petioles short (in the seedling), 

 semiterete, furrowed above on each side 

 of the midrib, slightly hairy. 



Nos. 1-4. Linear-lanceolate, acute, 

 small and scale -like. 



Nos. 5-7. Lanceolate, broadest above 

 the middle, cuspidately acute or shortly 

 acuminate, tapering into a short pe- 

 tiole. 



Nos. 8-11. Lanceolate, acuminate, 

 petiolate, much larger than any of the 



PIG. 251. Sapindus inaqualis. preceding. 

 Half nat. size. 



Acer Pseudo-Platanus, L. 



Pistil syncarpous, superior ; ovary of two carpels, two-celled, 

 each cell two-ovuled ; ovules collateral or slightly superimposed, 

 ascending, campylotropous ; radicle inferior, close to the hilum. 

 Only one ovule in a cell is habitually fertilised, generally, if not 

 always, the upper one when they are superimposed. 



Seed ovoid, slightly compressed laterally, somewhat narrowed to 

 an obtuse point at the upper end ; testa thin, ultimately membra- 

 nous ; hilum about the middle of the ventral aspect ; micropyle 

 inferior but pointing slightly upwards and contiguous to the hilum ; 

 chalaza very large, superior, covering nearly or quite the whole of 

 the upper part of the seed.
