i66 Notes and Gleanings. 



Chimese Primroses after Flowering. — They should be placed in a cold 

 frame, and have air plentifully. Towards the end of June, they should be repot- 

 ted in the same sized pots as before, most of the old soil being shaken from 

 them. The lights should be drawn on closely, and a very light sprinkling of 

 water given every evening, with shade from bright sun. When the plants 

 recover from the potting, admit air freely, and keep them well supplied with 

 water. At night, the lights may be drawn off, and replaced in the morning, tilt- 

 ing them high at back during dry, hot weather, and when heavy rains occur. In 

 August, shift the plants into six-inch pots, pursuing the same treatment as be- 

 fore. The plants will bloom finely in autumn, all bloom-stems showing before 

 September being pinched off closely. It is only the best that are worth keep- 

 ing ; for seedlings are better for a late autumn and spring bloom. 



There is no better plant for the parlor than this. 



Aloysia citriodora {Lemon Verbma) Propagation. — Cuttings may be 

 taken from the shoots of the current year ; and such are best when from three to 

 six inches in length, and when the wood is about half ripe, or a little hardened, 

 but not woody. They should have three joints, and not exceeding four if short- 

 jointed. The leaves should be removed from the lowest two joints, and the cut- 

 ting be cut through with a sharp knife immediately below the lowest joint. A 

 six-inch pot is large enough for a dozen cuttings. The pots should be drained to 

 one-third their depth, and then be filled up with a compost of sandy loam, fibrous 

 peat, and silver sand, in equal parts, surfaced with silver sand. The cuttings are 

 to be inserted in the sand up to the leaves, or nearly so, and placed round the 

 sides of the pot, at about an inch apart. A gentle watering being given, the pot 

 should be plunged in a mild hot-bed of from 70° to 75°, and slightly shaded from 

 bright sun. The atmosphere should be moist, and the sand also, but not exces- 

 sively so, otherwise the cuttings will damp off. If the atmosphere is close, they 

 will soon root, and be fit for potting off singly in six weeks. Harden them off 

 when well established. 



The modern name of this plant is Lippia citriodora. Plants may also be 

 raised from seeds ; but they seldom ripen in our climate. 



" The Botanical Magazine " for April figures the following new plants : — 



Saccolabium giganteum. — A rare and very beautiful orchid, introduced a 

 few vears ago from Rangoon, E.I. The species is nearly related to 6". violacea, 

 but differs in the shape and nervation of the lip. 



The flowers are whitish, with lilac and white lip. agreeably fragrant, and last 

 i.i full beauty about three months. 



CoRDYLiNE AusTRALis. —A handsome small tree from New Zealand, almC'St 

 hardy in the west of England, and wholly so in the Scilly Islands, where it has 

 flowered in the open air. It is often seen in greenhouses under the name of 

 Cordyline indivisa, which is a totally different plant, with broader yellow-green, 

 strongly-veined leaves, and a drooping panicle of larger flowers. The trunk of 

 this species is from twelve to twenty feet high, producing at the top a crowded 

 erect panicle of white flowers. It would probably prove hardy in our Southern, 

 and perhaps in the Middle States.
