the dehiscence of anthers by apical pores. 199 



with little indication of a special receptacle for nectar. 

 The number of stamens is usually small. The anthers are 

 basifixed and have generally the same elongate, linear or 

 subulate, form as in the preceding type. The pores are 



minute 



pore, and are very rarely continued down the sides. Often 

 the anther has thin, flexible walls which make possible a 

 bellows-like action in the ejection of the pollen.

ily, the floral structure is quite uniform. Flowers usually 



5-merous; petals usually large and highly colored, 



4- or 



sometimes 



into a tubular or campanulate corolla; stamens usually 

 twice as many as petals, rarely as many, or in some cases 

 indefinite, all similar or alternately reduced or imperfect ; 

 filaments long or short, thick or slender, straight or arcu- 

 ate, glabrous or glandular ; anthers basifixed, almost spheri-

 curved, dehiscing by a single terminal pore, rarely by two 

 terminal pores and very rarely by lal ' Mi - -- u - — 

 terminal pores. The connective shows

 usually minute, rarely capitate.

The more essential structural points and the 

 geographical distribution of the forms may be obtained 

 from the work of Bentham and Hooker or " 

 Prantl, the splendid elaboration of the South 

 forms in Flora Brasiliensis or the detailed monograph of 

 the family by Cogniaux. An examination of the indi- 

 vidual genera reveals the fact that there prevails in this 

 family a marked structural uniformity which instead of 

 bein" obscured by numerous minor differences, is only 

 made more conspicuous by them. The family includes 



irenera.
