to 4 ft. in height, radical leaves cordate, stem leaves ovate ampjexicaul, 

 with large drooping yellow flowers. Propagated by seeds and division. 



£'rigeron (L.) ? maxinuim Link et OUo. Stem 5 to 6 ft. high, much 

 branched, with large oblong semi-amplexicaul deeply-toothed leaves, and 

 showy white flowers. Frame ; seeds and division. 



^'ster (i.) acuminatus Mich. 



Podolepis {Lab.) gracilis Graham. Sweet's B. F. G. t. 285. 



Galardia (Lam.) aristata Pursh. 



Jsclepia* (i.) Gveeaidna Nutt. 



Houstonia (L.) purpurea L. Stem erect bi'anched, 5 to 4 in. in height ; 

 leaves linear lanceolate, with terminal corymbs of pale purple flowers. — 

 H. ^erpyllifolia Mich. Bot. Mag. 2823. Caespitose, Branches numerous, 

 rooting ; leaves spatulate, somewhat hairy ; peduncles elongated termi- 

 nated by a solitary white flower. This species and the preceding are 

 excellent furniture for rockwork i they also thrive well in small pots, well 

 drained, composed of tui'fy loam and peat. 



Phlox (Z>.) cordata Ell. Sweet B. F. G. n. s. t. 13. This is really a 

 handsome and very distinct species with smooth stems, 4 to 5 ft. high, 

 cordate oblong leaves, and corymbed panicles of purplish lilac flowers, 

 delicately fragrant. ■ — P. disticha Sabine. Stem erect, smooth, purplish, 

 3 to 4 ft. high ; leaves undulate, oblong, acuminate, smooth, margin rough, 

 panicles distichous, petals lanceolate distinct, flowers of a beautiful lilac, 

 fragrant. The distichous mode of flowering at once distinguishes this 

 species from its coordinates, it has perhaps the nearest affinity to P. undu- 

 lata Ait. 



Digitalis [L.) micrantha Roth. 



(Salvia (i.) johlomoides Ass. 



Phryma (L.) leptostachya h. 



Scutellaria (i.) serrata Andr. Rep. 494. Stem 18 in. to 2 ft. in height, 

 with ovate acuminate serrate leaves and terminal racemes of elegant purple 

 and white flowers. It succeeds best in peat soil. Division. 



Leonurus {L.) lanatus Pers. Introduced in 1752, but now become rare. 

 It is a curious and pretty species, of low growth, with densely woolly stems, 

 palmated woolly leaves, and verticillated villose sulphur-coloured flowers. 

 Hardy. Propagated by seeds and division. 



Phlomis {L.) pungens Willd. Sweet's B. F. G. t. 53. 



Chasmonia {Presl) incisa Presl. Bot. Reg. t. 1244. This genus has 

 emanated from the Linnean Moluccella, of the propi'iety of which there can 

 be no question : it attains the height of 6 or 7 ft. with numerous erect 

 branches from the bottom. Leaves cut-palmate; flowers in whorls of twelve 

 or fourteen, yellowish and lilac, calyx armed with strong spines. It is a 

 biennial, flowering from May until October. Cuttings and seeds. 



iysimaehia (i.) diibia Ait. 



Taxknthemdi {Neck, et R.Br.) mckna. Sweet. B. F. G. t. 272. This is 

 perhaps the most elegant of the red-flowered kinds ; the dark red flowers 

 exhibiting a peculiar contrast with the persistent scariose calyx. Flowers 

 from July to September. It may be occasionally increased by splitting the 

 crown ; but unless this operation is effected with due care, it is certain to 

 prove fatal to the plant. It has not produced seeds, consequently it is 

 very rare. 



Begonia (L.) semperflorens Link et Otto, not Bot. Mag. 



Habranthus {Herb.) robustus Herb. Sweet's B. F. G. new s. 1. 14. A bulb- 

 ous plant with a solitary rose-coloured flower, appearing throughout the 

 summer. Perfectly hardy. Propagated abundantly by seeds. 



Alstrcemerk (L.) psittacina Lehm. Sweet's B. F. G. t. 15. Stems several 

 from the same root, 18 in. to 2 ft. high, erect, maculate. Leaves oblong 

 lanceolate, twisted at the base, with many-flowered umbels of splendid 

 crimson, purple, and green flowers. Frame or mulch in winter ; propagated 

 by division and seeds. — Alpha. Sepf.9.\829.
