NOTES ON NEW OR HARE PLANTS. 5 



taking much in the character of growth of F. acuminata. The flowers 

 are of a rich blue-purple colour, more than an inch across, and pro- 

 duced in corymbs said to be even larger than those of F. hijchan,' 

 gcrformis. It is in some of the London nurseries. 



HeLIOPHILA TRIFIDA ^TniFID-LEAVED HeLIOPHILA. 



Brassicacece. Tetrad unamia Siliqxtosa. 

 A native of the Cape of Good Hope, from which it was introduced 

 in 1819, and is known also by the name of H. pinnala. It is a half 

 hardy herbaceous annual, and does well in the greenhouse, or if raised 

 in i)ots, and turned out in the open borders in May. It grows about 

 a foot high, branching, and produces a profusion of spikes of lovely 

 blue flowers, having a white centre. Each blossom is three quarters 

 of an inch across. Figured in Bot. Reg., p. 64. 



H0Y\ IMPERIALIS IMPERIAL HoYA. 



Asdepiadacece. Penlandria Digynia, 

 This, it is said, is the most noble climbing plant ever introduced 

 into this country. It bears large clusters of Howers, of a most beau- 

 tiful white waxy texture, similar to the well-known lovely H. carnosa, 

 except that the tiara-like rays in the centre are more of a bright purple 

 than crimson colour. Each separate flower, we are informed, mea- 

 sures three inches across, and being grouped together in large umbels 

 their appearance must be surpassingly magnificent. It was discovered 

 in Borneo by Mr. Low, jun., who some time ago went out purposely 

 to collect plants for the Clapton Nursery establishment. In remark- 

 ing upon it, in a letter from Sarawak, dated 12th January, 1S46, 

 Mr. Low observes, " On the next day, when in the territory of the 

 Gumbang Dyaks, I found another curious plant, belonging to Ascle- 

 piads; it is an epiphytal climber; there was but one individual, 

 growing from the decayed part of a tree, also overhanging the river. 

 The flowers are large and in umbels ; the leaves are leathery, and the 

 stem abounds in a white, perhaps acrid juice. The contrast between 

 the purple of the petals and the ivory white of the parts of fructifica- 

 tion renders it highly beautiful." The leaves are lanceolate, six inches 

 long, and the stems woolly. It is an invaluable plant, and we hope 

 soon to see every stove ornamented with it. 



Hydrolea spinosa — Spiny Hydrolea. 



HydToleaceee. Pentandria Digynia. 

 A most beautiful and neat growing evergreen greenhouse shrub, 

 introduced many years ago, but from an entirely inexplicable cause, 

 for it is of easy multiplication by cuttings and grows freely, it is still 

 a somewhat rare plant. It forms a compact bush, about a foot high 

 and as much across. The flowers, produced with remarkable free- 

 dom, are of a lovely bright blue colour, rather larger, but of a 

 similar shape to, Anagallis Monelli. It deserves to be grown in 

 every greenhouse, and will also, especially on account of its colour, of 

 which there is a deficiency, be found a valuable acquisition in the
