HAEMANTHUS 
Haemanthus (Tourn.) Linn. Amaryllidaceae (i). 60 sp. S. Afr. Firs, 
in cymose heads or umbels. 
Haematoxylon Linn. Leguminosae (n. 7). 1 sp. trop. Am, H. cam - 
pechianum L., the logwood. The young foliage is red (p. 157). In 
the leaf-axils are thorns. The heart-wood contains the dye-stuff 
haematoxylin and is largely used in dyeing ; it is broken into chips 
before use. 
Haemodoraceae. Monocotyledons (Liliiflorae). 9 gen. with 33 sp., 
Austr., S. Afr., trop. Am. Herbs with panicled infl., consisting of 
a number of cymes arranged in a racemose way (cf. Aesculus). Fir. 
regular or transversely zygomorphic (cf. Anigozanthos), $ , 3-merous. 
Sta. 3, inserted on inner perianth-leaves, with introrse anthers. 
G (3), sup. or inf.; ovules few in each loc., semi-anatropous. Stigma 
capitate. Capsule. Chief genera: Haemanthus, Lachnanthes, Wach- 
endorffa. [As defined by Benth.- Hooker, the order includes sub- 
orders VIII, IX of Liliaceae, and part of sub-order ill of Amaryllidaceae 
(Anigozanthos, &c.). It is placed in Epigynae by Benth.- Hooker, 
in Liliiflorae by Warming.] 
Haemodorum Sm. Haemodoraceae. 17 sp. Austr. 
Hakea Schrad. Proteaceae (11). 100 sp. Austr. Xerophytes with 
hard woody fruit. The seedlings show interesting transition stages 
(p. 29, and cf. Acacia) from entire leaves to the much divided leaves 
usually seen in the genus. 
Halenia Borckh. Gentianaceae (1. 3). 25 sp. As., Am.; alpine and 
arctic. 
Halesia Linn. Styracaceae. 7 sp. Japan, China, andS. E. ofN. Am. 
(cf. Epigaea, &c.). The Snowdrop-tree. Fruit winged. 
Halimocnemis C. A. Mey. Chenopodiaceae (10). 10 sp. Cent. 
As. 
Halimodendron Fisch. Leguminosae (ill. 6). 1 sp. N. and W. As. 
on salt-steppes. The outer leaflets are often thorny (p. 167). 
Halleria Linn. Scrophulariaceae (11. 6). 8 sp. Afr., Madag. 
Haloragidaceae. Dicotyledons (Archichl. Myrtiflorae). 8 gen. with 
90 sp., cosmop., but chiefly Austr. Land, marsh, or water plants, 
herbaceous, of very various habit (see gen.), and with inconspicuous 
firs. , solitary or in infl. The anatomy of the water forms is of interest* 
and also that of Gunnera, whose stem is polystelic. Fir. g or uni- 
sexual, usually bracteolate, regular, epigynous, usually 4-merous. 
Perianth in two whorls, or one, or absent. Sta. 8, obdiplostemonous, 
or fewer (down to 1 in Hippuris). Cpls. (1 — 4) ; ovary inf., multi- 
loc., with usually 1 pendulous anatropous ovule in each loc.; styles 
free. Nut or drupe. Embryo straight, in endosperm. Chief genera: 
Haloragis, Myriophyllum, Gunnera, Hippuris. The H. are undoubt- 
edly related to Onagraceae, as reduced forms. A gradual series may 
be traced, from the very complete flr. of Myriophyllum or Haloragis, 
down to that of Hippuris. Eichler and Warming also place the order
