 in catalogues, t^ee Cassandra, Cassiope, Leucotlioe, 

 Iiyonia, Oxydendrunx, Pieris, and Zenobia. 

 A. polifolia ((Niliuin-loiivftl). Wild lloseniary. Ji. pinky white, 

 drooping, soiiR'tiuiey tipped witli red ; corolla ovate, fiu-nislied 

 with ovate, rutlu-r leafy iinbricatt'd liracttMs. terminal, uniliellate. 

 June. I. linear lanceolate, mucrunnlate, with the niaii;ins more 

 or less revi.hite, qnite entire, jiliuieous heiieatli, with an elevated 

 rib, and reticadated veins, h. 1ft. 'i'hu numcruus varieties of this 

 very heautiful native shrub principally differ in the colouring of 

 the flowers. 



ANDROFOGON (from rt?ier, a man, and pogon, a 

 beard ; tufts of hair on flowers). Ord. Graminew. A 

 large genus of grasses with jjolyganious flowers. The 

 majority of species are of no horticultural value ; several, 

 however, are very ornamental sulijects, and thrive well in a 

 rich, deep soil. Easily propagated by seeds or by division 

 of the roots. The South European kinds succeed in the 

 open air if planted in a warm dry border. 

 A. citratum (C"itrus-leave<l). Synonymous with ^. SckoenantJnts. 

 A> SchcenanthUS. Lemon Grass. Jl. in threes ; spikes imbricate, 



conjugate, panicled. A handsome species, the leaves of winch 



emit a very fraj;rant odour when bruised, h. 2ft. India, 1786. 



Stove species. Syn. A. citratum. 



Other species worth growing are furcatus, halepensis, murlcatus, 

 piibescens, scoparius, sqtiarrosus, and xtrictus. 



Alf DROSACX! (from aner, a man, and salcos, buckler ; 

 in reference to the resemblance of the anther to an ancient 

 buckler). Including Aretia. Ord. Pritnulace(r. Dwarf 

 annuals or perennials, entirely alpine, agreeing in most 

 characters with Primula, but having the tube of tho corolla 

 narrowed at the mouth. An airy, well-drained, and par- 

 tially sunny position is essential in their culture. They 

 thrive well between fissures of rocks or stones with a ricli 

 sandy peat soil. Drought and a soiir soil are alike fatal, 

 and both will be greatly obviated if small pieces of sand- 

 stone are mixed with the soil. The woolly species are best 

 arranged beneath a jutting ledge of the rockery, which 

 will afford them protection from the hottest sunshine, and 

 from excessive wet in winter ; additional comfort will be 

 provided from tne latter ill if a piece of glass is placed 

 over them during the autumn and winter months. They 

 can also lie well grown, and make charming little s])eci- 

 mens, in pots, with rich sandy soil and thorough drainage. 

 Sprinkle sand among the small rosettes of leaves. They 

 are increased by divisions, cuttings, or seed; tue latter 

 should be sown as early as possible, and raised in a frame.

 Russia, 1755. This is a charming little biennial, well worthy of a

 freely, and a batch of young jdants almost invariably takes the 

 place of tlie old om^s. Syn. A. scpteutrionalis.

 (piires a iKutially shady position. Should be propagated from 

 seeds or cuttings, which latter strike freely. See Kig. 90.

 Robinson, "to great pertertiMU in tissnres between large rocks,

 will also grow on a level exposed spot, but in such a position 

 should be suivoiinded by half-buried stones."
