usually netted-veined. Principal genera :—Acorus, Orontsum, Anthu- 
rium, Pothos, Calla, Richardia, Colocasia, Caladium, Arum. 
To this cohort belong also Pandanacee, and several other less im- 
portant orders. 
Cohort IX. LILIALES. Ovary syncarpous; flowers hermaphrodite, 
very rarely unisexual, solitary or in spikes, racemes, or panicles, 
rarely capitate ; perianth of six (very rarely four) nearly similar pieces, 
or gamopetalous and six-lobed, regular (rarely irregular), usually all 
coloured and petaloid (sometimes coriaceous or subglumaceous); embrye 
immersed in a copious endosperm (not external to nor in a lateral cavity). 
Order 1. LILIACEZ. Stamens six, hypogynous or perigynous 4 
anthers usually introrse ; ovary tri-locular, ovules usually many in 
each loculus ; style entire ; fruit a capsule ; seed glabrous, with a 
membranous or crustaceous testa ; endosperm fleshy. Stemless herbs 
or shrubs with a simple or branched trunk; root fascicled or.stem 
bulbous. Principal genera:— Zulita, Vucca, Fritillaria, Lilium, Gagea, 
Agapanthus, Phormium, Llemerocallas, Aloe, Scilla, Allium, Hyacinthus, 
Orinthogalum, funkia, Asphodelus.| Among useful and medicinal — 
species are the Aloe socotrina, the Scilla or squill, the vanious species of 
Allium which yield the onion, leek, garlick, &c., the Asparagus offict- 
nalis, and Phormium tenax or New Zealand flax. 
[Mr. Bentham, in a paper read before the Linnean Society, but not 
yet published, arranges the monocotyledonous orders in four series, 
viz.:—1I. EPIGYN%. Flowers witha double, usually petaloid, perianth ; 
ovary usually inferior, syncarpous. 2. CORONARIE&. Flowers with 
a double, usually petaloid, perianth; ovary superior, almost always 
syncarpous. 3. NUDIFLOR#. Flowers usually achlamydeous, or with 
a dry scarious perianth ; ovary mostly apocarpous. 4. GLUMALES. 
Perianth replaced by membranous scales (pales or lodicules); ovary 
always uniovular. ‘The orders are arranged thus in the four series :—
