HAYLOCKIA (named in honour of Haylock, 
Dr. Herbert’s gardener). Orp. Amaryllidee. A mono- 
typic genus. The species is a small, half-hardy, bulbous 
plant, which thrives in a soil consisting of sandy loam 
with a slight intermixture of peat and leaf-mould, and 
is propagated by offsets. 
H. pusilla (small). 7. solitary; perianth erect, regular, the 
tube tinged with green, lin. to 2in. long, very slender, the 
limb whitish, sometimes tinged with red outside, funnel- 
shaped, lin. to 1jin. long. March. J. narrow-linear, spreading, 
developed in winter. ulb lin. in diameter. Buenos Ayres, 
1829 and 1899. (B. RB. 1371.) 
HAYNALDIA THAPSOIDEA. According to the 
‘Index Kewensis,” this is the correct name of Lobelia 
thapsoidea (which see). 
HAZEL-BUD MITE (Phytoptus avellane). Allied 
to the Currant-Bud Mite already described is the pest 
known by the name here adopted. Though its ravages 
are chiefly confined to the Hazel, yet at times it proves 
injurious to the Filbert. The symptoms of attack and life- 
history are identical with those detailed under Currant- 
Bud Mite. Im gardens this pest is not difficult to 
control, as the deformed buds may readily be seen early 
in spring, and as the pruning of Filberts usually takes 
place in March or April all that the gardener has to do 
is to remove the infested buds and burn them. See 
Currant-Bud Mite.

of flowers in Composite and Dipsacee ; and generally to

HEATING. The new horizontal tubular boiler 
(Fig. 440) of the Thames Bank Iron Company is finding 
considerable favour amongst market growers, for its 
economy, reliability, and ease with which any damaged 
or leaking part may be replaced with little loss of time. 
In fact, it has proved so excellent in every case when
