1. CALYCANTHUS, Linn. Sweet-sckntkd SirntrB. 

 Sepals numerous, imbricated ; tlieir bases united in many ranks into a i)ersistent 

 obconical cupsliajied tube; the outermost smaller and bract-like, the rest linear-oblong 

 and colored like the petals, deciduous. Petals in several rows on the mouth of the 

 tube, the inner ones shorter. Stamens numerous, inserted at and toward the top of 

 the tube, with very short persistent filaments, the outer (about 12) perfect, the inner 

 ones without antiiera ; anthers apicnlato, oxtrorso. Carpels usually numerous, distinct, 

 inserted upon the base and sides of the calyx-tube : styles terminal : ovules 1 or 2, 

 ascending. Akeues enclosed in the enlarged and at length dry ovoid or oblong 

 calyx-tube. Seed erect, without albumen : cotyledons foliaceous, convolute : radicle 

 inferior. — Shrubs ; leaves opposite, entire, without stipules ; flowers terminal, soli- 

 tary, purple or livid, more or less fragrant.

Order MYRTACE-aj, the Myrtle Family, a largo order of trees and shrubs, 

 chieny tropical and subtropical, with (uitire and pinuitate aromatic leaves, calyx- 

 tube adnato to the ovary, numerous stamens, and undivided style, has no American 

 representatives except near and below the tropic. ]?ut Eucalyptus, L'ller., a vast 

 genus of trees in Australia, forming there a large part of the forest growth, furnishes 

 several species which are advantageously planted on the Californian coast, from San 

 Francisco Bay southward. They make perhaps the most rapid growth of all shade 

 trees, and yet furnish excellent timber. In Australia some trees rival our Redwoods 

 in altitude and girth. The foliage of seedling trees consists of opposite leaves of the 

 ordinary kind, generally broad ; but when older they pro.luce alternate leaver of 

 another shape, usually narrower, longer, falcate, and hanging in a vertical position, 

 which is assumed through a twist of the petiole. The calyx never opens ; but the 

 upper part, shaped like a candle-extinguisher or an inverted cup, separates trans- 

 versely and falls away as a lid, under this is commonly another lid, thin and decid- 

 uous, whi(;h answers to tho concreted petals, and then the very numerous indexed 

 stamens rise up and expand, producing a ta,>?sel-like blossom, 'i'he fruit is a 3-5- 

 colled capsule imbedded in tho indurated calyx-tube, and t^|)ening at tho top : the 

 seeds numerous and small.
