by St. Patrick to illustrate familiarly the doctrine of the Trinity, 

 though at the present day Trifoliam repens is generally used for 

 that purpose. Fl. May, June. Perennial. 



2. 0. corniculata (Yellow Wood Sorrel). Stem prostrate ; flowers 

 yellow, smaller than 0. Acetosella, and borne in an umbel of 2-5 

 on a slender axillary peduncle. Perhaps truly wild in some parts of 



the south of England, and not un-

 Fl. all the summer. Annual.

1. /. noli-me-tangere (Yellow Balsam, 

 Touch-me-not). Characters described

A variety with orange-coloured 

 flowers, spotted with red-brown, has 

 been called /. fulva.

 petals and stamens equal in number to the sepals ; stamens alternate 

 with the petals ; ovary sunk in the disk, 2-5-celled ; fruit either a

 wrapped in a covering distinct from the capsule (called an arillns.) 

 A rather large number of plants are included in this Order, but

 of Europe, North America, and Asia, and a great number inhabit
