like projection of the lateral sepals, to which it is adnate. 

 From this consolidation o'i the stamen with the pistil the 



former is said to he gynandrous. 

 Lastly, make a clean vertical 

 section through the centre of 

 a flower, cutting as nearly as 

 may be through the median 

 line of the column and upper 

 p:irt of the flower-stalk {pedicd). 

 No trace of the ovary will be 

 found in the substance of the 

 column, but underneath the 

 attachment of the perianth, 

 apparently in the substance ot 

 the upper curved extremity of 

 the pedicel, indications are dis- 

 cernible of numerous rudimen- 

 tary ovules, in three series, in 

 the obscure cavity of the ovary. The observation is difli- 

 cult in this case, because in Dendrobes the ovules are usually 

 not perfectly developed until a considerable period after the 

 time of flowering. We lind, therefore, an ovary sheathed 

 by tlie adherent bases of the perianth-leaves to where they 

 become confluent with the pedicel. 



The flower of Dendrobe may be thus described : — 



Perianth si//>cTi'or, garnophyifous, irregular. 

 Stamen i {monandrous), gynandrous. 

 Pistil syncarpous, ovary infi.rior, 



3. Crinum asiaticum (known as Sukh-dursan, Buro- 

 kanoor, or Tolabo). — Separate a single flower from one of 

 the many-llowered clusters in which they grow. The 

 perianth consists of a long, nearly cylindrical, or obtusely
