Piadrlfolia (four-leaved).* ft. white, small, sweet-scented, 

 red nectaries ; umbels twin, terminal, loose-flowered ; 

 pedicels filiform. July. I. ovate, acuminated, petiolate ; those 

 in the middle of the stem larger, and four in a whorl ; the rest

A. Sullivanti (Sullivant's). Similar to A. syriaea, but having 

 larger and deeper coloured flowers. 



A. syriaea (Syrian).* ft. pale purple, sweet scented, in large, 

 loose, drooping umbels. July. I. opposite, lanceolate-oblong, or 

 oval, gradually acute, tomentose beneath. Stems simple. /*. 3ft. 

 to 5ft North America, 1629. SYN. 4. Cornuti. 



Ascyrum continued. 



Hypericum. They require to be protected during winter 

 by a frame ; for this purpose they should be grown in pots, 

 as they never exist long in the open border. A compost of 

 peat, pure leaf soil, and sand, in equal portions, suits them 

 well; young cuttings of the shrubby kinds will root in 

 sand under a hand bell glass. Propagated by careful 

 divisions of the roots in spring. All may be raised from 

 seeds. 



A. amplexicaule (stem-clasping), ft. yellow, few, axillary, and 

 terminal; corymbs naked. July. I. stem-clasping, ovate, cordate, 

 sinuately-curled. Stem dichotomously panicled. h. 2ft. North 

 America, 1823. The flowers and leaves are longer in this than 

 in any other of the species. 



A. Crux Andrew.* St. Andrew's Cross, ft., petals narrow- 

 pale yellow, nearly sessile, in terminal corymbs. July. I. ovate- 

 linear, obtuse, usually in bundles in the axils. Stem shrubby, 

 round, h. lit. North America (in sandy fields), 1759. This proves 

 to be quite hardy in many situations. 



A. hypericoid.es (Hypericuui-like). /. yellow. August. I. linear- 

 oblong, obtuse, h. 2ft. North America, 1759. 

 A. Stans (standing). St. Peter's Wort. ft. yellow. August. I. 

 oval or oblong, somewhat clasping, h. 2ft. North America, 1816. 

 ASHES. The earthy or mineral particles of com- 

 bustible substances, remaining after combustion. Ashes 

 are amongst the most economical manures. 



Vegetable Ashes are generally the best application for

A. tnberosa (tuberous).* 

 disposed in a terminal si 



tered, oblong-lanceolate, hairy. Stems erectish, divaricately 

 branched at top, very hairy, h. 1ft. to 2ft. North America (in 

 stony, sandy fields and woods), 16SO. A desirable hardy herba- 

 ceous border plant. See Fig. 158.

 olate, hairy. Stems erectish, divaricately 



, (variegated). /., petals and foliola of corona white, 



fructification red, in dense umbels, very handsome- umbels 

 almost sessile ; pedicels hairy. July. I. opposite, ovate, petiolate, 

 Crinkled naked. Stems simple, erect, variegated with purple! 

 h. 3ft. to 4ft. New York to Carolina (on dry, sandy hills), 1597; 

 A. verticillata (whorled). ft., corolla with yellowish green petals 

 and white nectaries ; umbels many-flowered. July and August. 

 1. very narrow, linear, thick, quite glabrous, usually verticillate 

 but sometimes scattered. Stems erect, often branched having 

 a downy line on one side. h. 1ft. to 2ft. New Jersey, 1759. 



ASCYRON. See Hypericum Ascyron. 



ASCYRUM (from a, without, and skyros, hard ; that is 

 to say, a plant which is soft to the touch). OBD. Hyperi- 

 cina. A genus of elegant little herbs and sub-shrubs, with 

 sessile, entire leaves, destitute of pellucid dots, but usually 

 furnished with black dots beneath. Flowers resembling 



manuring boggy, cold, and, consequently, sour and unprofit- 

 able land, in quantities of about forty bushels per acre, 

 thinly and evenly distributed. The annual exhaustion of 

 salts from large crops of grain, roots, and grass, is from 

 1801b. to more than 2501b. per acre ; and the aggregate of 

 a few years will so far impoverish the soil in one or more 

 of the principles necessary to sustain a luxuriant vegetation, 

 that it will cease to yield remunerating returns. The ashea 

 of vegetables consist of such elements as are always re- 

 quired for their perfect maturity, and it is evident they 

 must furnish one of the best saline manures which can be 

 supplied for their growth ; they contain, in fact, every 

 element, and generally in the right proportions, for insuring 

 a full and rapid growth. Both gardener and farmer will 

 therefore perceive the great value of Ashes to their crops. 



Coal Ashes. The bituminous and anthracite coals afford 

 Ashes, and, although inferior in quality to those made from 

 wood and vegetables, are, like them, a valuable manure, and 

 they should be applied to the land in a similar manner. If 

 they contain many cinders, from not having been thoroughly
