! Properties. The inner bark of the Elm is slightly bitter and astringent, 
i but it does not appear to possess any important quality. The substance which 
I exudes spontaneously from it is called Ulmin ; it is also found in the Oak, 
ji Chestnut, and other trees, and, according to Berzelius, is a constituent of most 
! kinds of bark. Turner, 700.

Order CXXVII. STILAGINACE.E. 
i StilaginEjE, Agardh’s Classes, 199. (1824) ; Von Martins Hort. Reg. Monac. (1829). 
I Essential Character. — Flowers unisexual. Calyx 3- or 5-parted. Corolla 0. Sta- 
I mens 2, or more, arising from a tumid receptacle ; filaments capillary ; anthers innate, 
I! 2-lobed, with a fleshy connective and vertical cells opening transversely. Ovary superior ; 
I stigma sessile, 3 -4-toothed. Fruit drupaceous, with 1 seed and the remains of another, 
j Seed suspended ; embryo green, with foliaceous cotyledons, lying in the midst of copious 
fleshy albumen. — Trees or shrubs. Leaves alternate, simple, with deciduous stipules. 
, Affinities. An obscure order, of the limits of which nothing has been 
j well made out. Judging from the genera Stilago and Antidesma, it is very 
I near Urticacese, from which it is chiefly distinguished by the great cushion- 
i shaped disk, remarkable anthers, and unelastic filaments ; in all which charac- 
ters it resembles Hensloviacese, which are dicarpellary and polyspermous. 
! The male specimens have sometimes a striking resemblance in inflorescence to 
i East Indian Cupuliferse.

: . Essential Character. — Flowers unisexual, amentaceous, achlamydeous. Males: 
I Stamens 6, rarely 8, somewhat monadelphous ; anthers 2- or 4-celled, opening lengthwise. 
Females: Ovary 1 -celled, surrounded by several hypogynous scales; OfwZe solitary, erect, 
•. vnth a foramen in its apex ; stigmas 2, subulate, or dilated, and petaloid. Fruit drupa- 
I ceous, often covered with waxy secretions, and with the hypogynous scales of the ovary, 
' become fleshy and adherent ; or dry and dehiscent, with the scales distinct. Seed solitary, 
I erect ; embryo without albumen ; cotyledons 2, plano-convex ; radicle short, superior. — 
■ Leafy shrubs, with resinous glands and dots, the leaves alternate, simple, with or without 
stipules. 
Affinities. One of the approaches made by these plants is to Ulmaceae 
' and Betulacese, from the former of which they are readily known by their 
amentaceous flowers and want of a perianth ; from the latter by their’ erect 
ovules, aromatic leaves, and 1 -celled ovary. In the latter respect they resem-
