Tulip-tree. 



Sepals 3, colored (greenish-white or yellowish), imbricate 

 in aestivation, reflexed, early deciduous. Petals 6, imbri- 

 cated in two series in aestivation, very broad, nearly erect, 

 so as to form a somewhat bell-shaped corolla, hypogynous, 

 deciduous. Stamens indefinite, hypogynous in several se- 

 ries, nearly as long as the petals, deciduous : filaments fili- 

 form : anthers elongated-linear, adnate to the outer face of 

 the connective (c.drorse), two-celled ; the cells contiguous, 

 opening longitudinally. Pistils very numerous, closely im- 

 bricated upon the prolonged receptacle (gynophore) into a 

 fusiform column as long as the petals : ovary sessile by a 

 broad insertion, one-celled, two-ovuled : style laterally 

 winged (or flattened anteriorly and posteriorly), entirely ap- 

 pressed : the stigma unilateral at its summit, cristate, recurv- 

 ed. Ovules collateral, pendulous from near the middle of 

 the ventral suture, anatropous, their raphes face to face. 



Fruit a fusiform cone or strobile, composed of the closely 

 imbricated samaraeform carpels, which at maturity fall away 

 from the elongated and bodkin-shaped persistent woody axis :
