its determination must therefore be doubtful ; but No. 743, of which we 

 have in Herb. Mus. Brit, an excellent sketch and a single opening flower, 

 is identical with Xo. 721 {II. WfUoltachil Rchb. f.). Kriinzlin places 

 the two species in different sections (3 and 4 respectively), but there is 

 very little distinction between the sections.
