Cochliostemas are handsome stove-flowering perennial 

 plants, closely related to the Commelinas, and are of 

 comparatively easy culture, thriving well in ordinary

 early spring, or by seeds, to ulitain which the flowers 

 must be artificially fertilized. The seeds should be sown 

 as soon as ripe in shallow pans of light, peaty soil, and 

 placed in a warm, close atmosphere until germinated. 

 As soon as the seedlings are large enough, they should 

 be potted singly into thumb-pots, and shifted on as 

 often as they require it, when they will flower in about 12 

 months. The chief reason why Cochliostemas are grown 

 in America so little is, probably, that we have to keep a 

 much more humid atmosphere in stove-houses here than 

 in England, and that is very much against all stove- 

 flowering plants, causing the season of blossoming to be 

 very short.

 Cochliostema odoratissimum is much like C. Jacoii- 

 nniim. Is a very interesting plant of rapid growth and 

 easy culture. It is raised from seed. It seeds freely 

 when fertilized at the proper time. Only a few of the 

 stronger or larger flowers should be allowed to bear seed. 

 Sometimes a simple shaking of the flower stalk will ac- 

 complish the necessary work of fertilizing, but it is 

 safer to employ the regular method to insure thorough 

 impregnation. The seeds ripen within 6 weeks' time, and 

 they can be sown soon thereafter. In 5 or 6 months from 

 seed the plants will bloom. The flowers, while not very 

 showy, are fragrant and interesting. The plant itself is 

 ornamental by reason of its curiously marked, striped 

 and veined leaves. The plant thrives best in rich, light, 

 loamy soil. First sow in boxes or seed pans in light, 

 sandy soil ; then traiis|ilant ini" ^in.ill pots; keep the 

 voung plants in a warm, iimi^t |.lai a- and repot before 

 the pot is filled with n.uts. i„ vi i- alli.wing the plant to 

 get "hard," as it is called, but ke<-|) it growing continu- 

 ously, and when in 6- or 7-inch pots, allow the plant to 

 get somewhat pot-bound and give more air, and it will 

 soon set flower buds. Then place a mulch of old cow- or 

 sheep-manure on the top of the pot, or use liquid manure 

 once or twice a week, keeping the plant in a cool posi- 

 tion. The above treatment will secure numerous flowers 

 over a long period. Fall and winter, h. A. Siebrecht.

COCOS (Portuguese, monkey, from the nut, which sug- 

 gests a monkey's face). PalmAcece, tribe Cocolnece. 

 This genus includes the Cocoanut tree, C. nucifera, and 

 a few palms that are cultivated for ornament in the 

 north under glass, and in S. Fla. and S. Calif, as ave- 

 nue and ornamental trees. Of the species cult, for or- 

 nament, C. Weddelliana is by far the most important. 

 It is sold in great quantities from 3- and 4-inch pots 

 when the plants are 12-15 in. high. They are favorite 

 house-plants, as their culture is easy, and they grow 

 slowly and retain their beauty a long while. They are 

 much used in fern dishes. As a house-plant, C. Wed- 

 delliana is probably the most popular species of all the 

 smaller palms. It is especially snitalile for table deco- 

 ration. The geiui^ i^ alhiil tn 'M axiniiliana and Attalea,

The Cocoanut Palm naturally grows on the seashore, 

 or in its inmiediate vicinity, and does not bear well 

 when at a great distance from salt water, although its 

 growth may be strong. In cultivation, this fact is kept
