NOTES AND /ABSTRACTS. 815 



Huckleberries. By F. W. Card (U.S.A. Exp. Stn. Rhode Is., Rep. 

 1903, pp. 216-222 ; 2 plates). — For many years attempts have been made 

 to find some sure and speedy method of propagating the Blueberry 

 (Vaccinium corymbosum). Various methods have been tried with but 

 little success, but a fairly promising one seems to have been hit upon. A 

 moderate bottom-heat, with moss {Sphagnum) in which is mould taken 

 from about the plants, is the best to use. Root grafts are made, and these, 

 with careful handling, root well. Cuttings usually fail. — F. J. C. 



Huernia OCUlata. — By A. Berger (Gard. Chron. No. 921, p. 132, 

 fig. 54, August 20, 1904). — The genus Huernia is very nearly allied to 

 the genus Stapelia, and this species very much resembles plants of that 

 genus. It was first introduced into this country in 1880, but it appears 

 subsequently to have been lost. It was reintroduced into cultivation in 

 1901, and now flowers annually in Sir Thomas Hanbury's garden at La 

 Mortola. It is a pretty little plant, bearing purple blossoms with white 

 centres, which are produced upon very short pedicels ; it is easily propa- 

 gated, and flowers from August to October. — G. S. S. 



Hunnemannia fumariaefolia. By S. Mottet (Rev. Hort. pp. 68-70, 

 Feb. 1, 1904 ; 1 woodcut). — Introduced in 1827. Resembles outwardly 

 Eschscholtzia californica, but differs materially physiologically, being herb- 

 aceous and with longer flowering period, while the flowers last several days, 

 a point which M. Mottet considers entitles it to greater recognition for 

 bouquet purposes. Native of Mexico, and easy of culture from seed in 

 warm positions. — C. T. D. 



Hydrangea hortensis rosea (Gartenflora, Dec. 1, 1904, p. 617 ; 

 coloured plate). — This new variety has recently been imported from Japan. 

 The colour of the flowers is of a much darker pink than that of the 

 varieties hitherto introduced. — R. C. R. N. 



Hypericum, East Asiatic Species. By R. Keller (Encjl. Bot. 

 Jahrb. xxxiii. March 1904, pp. 547-554). — An enumeration, with descrip- 

 tion of several novelties, of the species collected in China mainly by 

 Giraldi, and in Japan by Faurie. — A. B. R. 



Impatiens Holstii. By H. Conrad (Die Gart. No. 44, p. 523, 

 July 30, 1904). — A new introduction from East Africa and somewhat 

 allied to I. Sultani. The plant grows 50 centimetres high, and forms a 

 bush with several deep red- coloured stems ; dark green leaves with a red 

 midrib. In flower it varies more than I. Sultani, and already five different 

 colours are offered for sale by a Continental firm — carmine, orange, rose, 

 scarlet, and dark red. — G. R. 



Impatiens Oliveri. By A. O. (Garden, No. 1717, p. 266 ; 

 15/10/1904). — Impatiens Olivieri, introduced from Uganda last year, 

 is of vigorous habit and flowers freely. Sir John Kirk found it growing 

 in clumps at an elevation of 6,800 feet, about 300 miles up country, on 

 volcanic rocks. It grows about 4 feet high, and branches freely from the
