420 ENDLICHER’S NATURAL SYSTEM. 
Section 2. Hysterophyta. Plants formed on languid or decay- 
ing organisms ; nourished from a matrix ; all the 
organs developing at once, and perishing in a 
definite manner ; as in Fungi. 
Region 2. Cormopuyta. Plants with stem and root in opposite 
directions ; spiral vessels and sexual organs distinct 
in the more perfect. 
Section 3. Acrobrya. Stem growing at the point only, the 
lower part being unchanged, and only used for 
conveying fluids. 
Cohort 1. Anophyta. Having no spiral vessels ; both sexes 
perfect ; spores free in spore-cases. Examples, 
Hepaticze and Musci. 
Cohort 2. Protophyta. Having vascular bundles more or 
less perfect ; male sex absent. Spores free 
in one- or many-celled spore-cases. Examples, 
Filices and Equisetacez. 
Cohort 3. Hysterophyta. Having perfect sexual organs ; 
seeds without an embryo, polysporous ; para- 
sitic. Example, Rhizanthez. 
Section 4. Amphibrya. Stem growing at the circumference. 
Examples, Graminez, Liliacez, [ridacez, Orchi- 
dacez, and Palmacez. 
Section 5. Acramphibrya. Stem growing at both the apex 
and circumference. 
Cohort 1. Gymnosperme. Ovutes naked, receiving impreg- 
nation immediately by the micropyle ; as in 
Conifere. 
Cohort 2. Apetale. Calyx absent, rudimentary, or simple, 
calycine or coloured, free or united to the 
ovary. Examples, Cupuliferze, Urticacez, 
and Polygonez. 
Cohort 3. Gamopetale. Both floral envelopes present, the 
outer calycine, the inner corolline, the latter 
being monopetalous ; rarely abortive. Exam- 
ples, Compositz, Labiatz, Scrophularinez, 
and Ericacez. 
Cohort 4. Dialypetale. Both floral envelopes present, the 
outer being monosepalous or polysepalous, 
free or united to the ovary, calycine or some- 
times corolline ; the inner being corolline with 
distinct petals, or rarely cohering by means of 
the base of the stamens, and with an epigy- 
nous, perigynous, or hypogynous insertion ;., 
rarely abortive. Examples, Umbelliferze, Ra- 
nunculaceze, Cruciferee, Caryophyllee, Rosa- 
cere, and Legumincse.
