uniflori bractea vacua sepe cum axi abortivo v. flore tardo potius ei

The occurrence of an apparently abortive axis or flower-bud on the 
single-flowered scapes opposite to the bract is, in this plant, as in 
U. gibba, &c. (North American sp.), especially frequent. It is an in- 
teresting instance of a secondary superseding a primary axis, and of a 
definite inflorescence in a group in which an indefinite raceme prevails.
