MEMOIRS OF THE NEW YORK BOTANICAL GARDEN.

The inflorescence axis emerged from the sheathing leaves at a 

 distance of about 8 or 9 cm. from the bulb and was distinctly apoge- 

 otropic with the peduncles attaining a length of 14 to 18 cm. The 

 flower stalks were extremely sensitive to light, soon showing apoge- 

 otropic curvatures. The etiolated flowers were enclosed by two trans- 

 lucent bracts united except at the tip and projecting beyond the flower 

 5 or 6 mm. These sheathing bracts arose about 5 or 6 mm. from the 

 base of the flower tube. The separate portions of the perianth were 

 about 16 mm. long, ovate and with the adnate stamens apparently 

 perfect. The relative proportions of the stamens and pistils were as 

 in the normal. (Fig. 144.) 



Fig. 143. Normal culture of Milla unijlora. 



The normal leaf of Tritelia = Milla is 12 to 15 cm. long and 8 

 to 10 mm. wide, being perfectly plane in cross section, while the 

 etiolated are crescentic. The flower and its stalk are about 18 

 cm. long and become negatively geotropic after fertilization. The 

 sheathing bract is about 2.5 cm. long, splitting as in etiolated 

 specimens and is dorsiventral. The ovary is about 2 cm. long and 

 the perianth about 3 cm., being variously colored and marked with 

 a purple midrib. The open perianth is wheel-shaped. (See Fig.
