The central tooth and the processes on the face of the coronal -lobes vary 

 exceedingly in length in different specimens, but I find no other distinction. '1 he 

 shortest measurements given belong to the type (Whyte's specimen), the longest are 

 from Buchauiin's specimen, whilst that collected by Scott- Elliot is interniedi.ite 

 between the two in the length of these organs. The flowers have a pleasant od»)ur» 

 according to Buchanan. 



17. S. aciculare, X. E. Br. Plant probably dwarf, branching. 

 Stems (in the specimens seen) 2-3 in. long, pubescent with minute 

 white curved hairs, as is also all the rest of the plant except the 

 corolla. Leaves J- J in. apart, subsessile or very shortly petiolaU%
