TREWIA NUDIFLORA. (Linn.) A middling sized tree, young branches angled, young parts pubescent, stipules

 tapering acumen at the ape^ finely venose, 4-7 inches long by 3-5 J broad, petioles l£-3 inches long. Male, racemes pendulous 

 many flowered as long as or exceeding the leaf slightly stellato-puberulous, flowers about 3 lines long generally 3 together with a

Analysis. 



1. Branch of a male tree in flower (life size.) 



2. Portion of a male raceme highly magnified. 



3. A male flower bud just opening, calyx valvate. 



4. A 3-sepaled male flower, no disk, no rudiment of ovary. 



5. A 4-sepaled male flower. 



6. Anthers (front and back view) basifixed. 



7. A branch of female tree in flower (life size.) 



8. Female flower, 3 styles and stigmas, this belongs to a 3-celled ovary ; when the ovary is 4-celled there are 4 styles, (the calyx 



fallen off leaving only an undulated ring ?) 



9. Female flower showing the calyx, 



10. Portions o£ the stigma highly magnified. 



11. Ovary cut vertically, ovules pendulous. 



12. A 3-celled ovary cut transversely. 



13. A 4-celled ovary cut transversely, (the calyx has fallen away from all my specimens of the female flower. No. 9 is copied 



from Wight's drawing, the rest from dried specimens.)
