Parva. Axis demersus subramosus segmentis foliaceis capillaceis utri- 

 culiferis. Scapus nudus v. squamis (1-2) minutis instructus; scapi 

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

 opposita observatur. Calyx lobis parum inaequalibus capsula matura 

 valde brevioribus. Corolla labio inferiore integro calcaris basin am-

 rioris ad apicem calcaris 2-3 lin. 



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.
