 very short; the 4 alternate with the petals anther-bearing, the others imperfect 

 and scale-like. Styles 2, short. Capsule opening loculicidally from the top ; 

 the outer coat separating from the inner, which incloses the shigle large and 

 bony seed in each cell, but soon bursts elastically into two pieces. — Tall shrubs 

 or small trees, with straight- veined leaves, and yellow perfect or polygamous 

 flowers. (Ancient Greek name applied to the Medlar, or some similar tree.) 



1. H. virginiana L. Leaves obovate or oval, wavy-toothed, somewhat

3. LIQUIDAmBAR L. Sweet Gum Tree 



Flowers nsually monoecious, in globular heads or catkins ; the sterile arranged

 scales ; filaments short. Fertile flowers consisting of many 2-celled 2-beaked 

 ovaries, subtended by minute scales in place of a calyx, all more or less cohering 

 together and hardening in fruit, forming a spherical catkin or head ; the cap- 

 sules opening between the 2 awl-shaped beaks. Styles 2, stigmatic down the 

 inner side. Ovules many, but only one or two perfecting. Seeds with a wing- 

 angled seed-coat. — Catkins raceraed, nodding, in the bud inclosed by a 4-leaved 

 deciduous involucre. (A mongrel name, from liquidus, fluid, and the Arabic
