culum, roundifh on the outCde of the cafyx, al- 

 moft entire, with a longitudinal ridge efpecially 

 towards the apex, the parciof the petal neareft the 

 bafis almoft femicylindincal, embracing the 

 parts beneath, the difcus of the petalum depreffed 

 on both iides, turning upwards near the mar- 

 gin ; where the divided tube ends, and the 

 limb begins to unfold, are two cavities, which 

 comprefs the ah beneath : Ala, two petala, e- 

 qual, on each fide the flower, under the vexU- 

 lum, their margins incumbent, parallel, fubro- 

 tundo-oblong, broader outwards, the upper- 

 margin frraighter, the lower rounder ; the ba- 

 fts of each bifid, the infei'lor part flretched into 

 an unguis, inferted into the fide of the receptacu- 

 lum, about the length of the calyx, the upper 

 Ihorter, and bent : Carina, the loweft petalum 

 often bipartite, under the Vexillum, and between 

 the ala, boat-fhaped, concave, the fides com- 

 prefTed, fet like a boat in the water, the bafis 

 mutilate, of which the inferior part extends into 

 an unguis the lengtli of the calyx, and inferted 

 into the receptaculum ; but the lateral and fuperi- 

 or fliort laciniazre infolded with the correfpon- 

 dcnt part of the ala ; the fides of the carina 

 are fimilar to the ala both in fhape and fitua- 

 tion, except that they are inferior and interior ; 

 the carinal line runs ftraight as far as the mid- 

 dle, and then rifes in the fegment of a circle,
