Primulas. — I was disappointed with these plants, being there at a time 

 when this genus is perhaps at its best. In the gardens I visited no 

 special attempt is made to grow them well, nor do the British kinds 

 flourish so well as in many parts of Britain. 



Japanese Maples. — -These are not as yet grown in many gardens. 

 A. i)almatum\di>T. rubrum andysiv. dissectum rubrum seem the commonest. 

 Even at Trewidden, where there are splendid specimens of these plants, 

 no attempt has been made to mass them for colour effect. Yet the 

 luxuriant health and brilliant colouring of the few plants I saw fore- 

 shadow a great future for these maples in Cornish gardens. 



Tropceolum majus Boule de feu." — At Trewidden a fine form is 

 grown under this name. It is a climbing plant with medium- sized 

 flowers of an intense orange red, freely borne, and standing out well 

 from the small, very dark, villous leaves, which are of a peculiar sage- 

 green and purplish hue. 



Greenhouse Plants. 



Dimorpheca Echlonis. — In flower at Trewidden in April. 

 Decorative pelargonium "Purity." Very beautiful as grown at 

 Carclew. 



Wild Plants. 



Scilla verna (?). — A minute erect scilla, common at Land's End, 

 growing amid the Thrift on the cliffs. Although the bulbs are often 

 buried several inches, the flowers are barely raised above the ground level, 

 and are of a purplish-blue colour, borne on few-flowered scapes towards 

 the latter part of April onwards. 



Armeria vulgaris (Thrift). — Very common. Judging from the leaves, 

 there would seem to be more than one form. 



Arum italicum. — Not uncommon in hedgerows. I found it on 

 St. Michael's Mount, and what was probably a variety of the same species 

 in the woodlands round Carclew. 



Cotyledo?i umbilicus. — Very common on walls by roadsides. The 

 greenish -yellow flowers are regularly disposed on a relatively tall scape, 

 and are open in May onwards. I have flowered it at Isleworth. It bears 

 various local names, such as "Pancakes," "Wall-Pennywort," &c. 



Cochlear ia officinalis. — On the Logan Eock, bearing its dwarf white 

 flowers throughout the early summer. Fairly common in a few localities. 



Cochlearia sp. — On Logan Rock. This is a very dwarf and compact- 

 flowered form, and is of considerable horticultural merit as a rock plant. 

 It is not specifically distinct from C. offi,cinalis. 



Caltha palustris nana ple^ia. — A very good form of this plant, in 

 which the reproductive organs are completely suppressed, and which is 

 very floriferous and only two to three inches in height, I noted in the 

 garden of Mr. Casley at Penzance. He told me that a friend of his had 

 gathered a root of this plant growing wild in a ditch a few miles from 

 the town and brought it to his garden. Still it is probable that this is 

 an instance of escape from cultivation, or of pollen having been carried 

 by insect agency from a garden form to a wild one.
