LILIIFLORAE 
Liliiflorae. The 9th cohort (Engler) of Monocotyledons (p. 125). The 
5th cohort (Warming) of Monocotyledons (p. 138). 
Lilium Toum. ex Linn. Liliaceae (v). 45 sp. N. temp. Herbs with 
scaly bulbs (p. 152), leafy stems and firs, in racemes. The honey is 
secreted in long grooves at the bases of the perianth-leaves. The 
firs, of many sp. are adapted to Lepidoptera. Z. Martagon L. gives 
off its scent at night (cf. Oenothera). Z. bulbiferum L. is reproduced 
vegetatively by bulbils in the leaf-axils. In most sp. with hanging 
firs, the capsule when ripe stands vertically upwards, so that the 
seeds can only escape when it is shaken. Many sp. of lily are garden 
favourites. 
Limnanthaceae. Dicotyledons (Archichl. Sapindales). A very small 
order (2 gen. with 5 sp. N. Am.) sometimes united to Geraniaceae, 
but with the ovules as in coh. Sapindales. Herbs with exstip. alt. 
leaves and regular $ firs., 3 — 5-merous, with two whorls of sta. 
Ovary 3 — 5-loc., ovules 1 in each loc., ascending, the micropyle facing 
outwards and downwards. Fruit a schizocarp. Seeds exalbuminous. 
Genera: Llmnanthes, Floerkea. Placed in Geraniaceae by Benth.- 
Hooker, in Gruinales by Warming. 
Limnanthemum S. P. Gmel. Gentianaceae (11). 20 sp. trop, and 
temp. Z. ( Villarsia ) nymphaeoides Hoffmgg. et Link, S. England, 
is a water-plant with habit of Nymphaea, and so are several others. 
The infl. appears to spring from the top of the leaf-stalk, but really 
the floating leaf springs from the infl. axis. As Goebel points out, 
this is an advance upon the Nymphaea construction, as the materials 
going from leaf to seeds have not to travel to the bottom of the pond 
and up again. 
Limnanthes R. Br. Limnanthaceae. 4 sp. Pacific N. Am. 
Limnobium Rich. (Hydro my stria G. F. W. Mey., Trianea Karst.). 
Hydrocharitaceae. 3 sp. Am. Z. (H) sto loniferum Griseb. (T. bogo - 
tensis Karst.) is a small floating plant often cultivated. It reproduces 
vegetatively by ‘runners’ (cf. Hydrocharis). Its root-hairs are used 
to show circulation of protoplasm. Only the $ plant is known 
in Eur. 
Limnocharis Humb. et Bonpl. Butomaceae. 1 sp. trop. Am. [Z. 
Humboldtii Rich. = Hydroc leys Commersonii Rich.] 
Limodorum (Tourn.) Linn. Orchidaceae (4). 1 sp. S. Eur. A leaf- 
less saprophyte with no chlorophyll (cf. Epipogum). The 4 lateral 
sta. are sometimes fertile. 
Limonia Linn. Rutaceae (x). 6 sp. trop. Afr. and As. Some sp. 
in the leaf-axils have thorns (leaves of branch, as in Cactaceae). 
The fruit of Z. acidissima L. is used in Japan as a substitute for soap. 
Limoniastrum Moench. Plumbaginaceae. 3 sp. Medit. 
Limosella Linn. Scrophulariaceae (11. 8). 7 sp. cosmop. Z. aquatica 
L., mud -wort, in Brit, (rare), a small plant growing on the banks of 
ponds. It multiplies by runners.
