The bloiToms of this fpecies of Trefoil grow in little round balls or clufters from the alas of the leaves, and 

 hence it has received its name of glomeratum. 



It may be diftinguimed from the Jlriatum, to which it bears fome affinity, by being in every part fmooth, in 

 having its balls much rounder, and the teeth of the calyx fpreading backward ; its bloffoms alfo are of a brighter 

 red colour. 



Not being a plant which ftrikes the eye much at a diftance, it is probably often overlooked ; with us, how- 

 ever, it is certainly fcarce. Mr. Ray found it about Saxmundham in Suffolk ; Mr. Doody about Blackheath, and 

 near Greenhithe ; Mr. Hudson in the IJle of Sbepey \ Mr. Rose about Norwich, and Dr. Goodenough on 

 Hanwell Heath. I have found it on Blackheath for feveral years, yet not plentifully ; it is fond of a gravelly 

 fituation, with fome degree of moifture ; hence it muff, be looked for in the depreffed parts of the heath. The 

 plants growing near it were the Trifolium Jiriatum, ornithopodioides, and Sagina procumbens ; and at no great dif- 

 tance Callkriche autumnalis, Montia font ana, and Pep/is Portula. 



It flowers in June,
