On destroying the Mealy Bug and Wfiite Scale. 57 



The clusters are pendulous. One of 

 these weighed 35 lbs., and contained 

 5640 berries. The seeds (a) are he- 

 mispherical, and by dissection show 

 the lateral embryo (6). 



As the flowers are sessile {Jig. 12.y"), 

 so are the germs {e) ; and were each 

 of the divisions to increase, it does 

 not appear probable that there would 

 be sufficient space left on the stalk for 

 them to attain perfection. 



Mr. Nickson, the intelligent gar- 

 dener at Hale, has been so good as 

 to furnish me with the following de- 

 tails respecting its culture: — 

 < It is planted in light sandy soil, in a sort of well, 6 ft. 

 square, and 3 ft. 6 in. deep. During summer it requires 100 

 gallons of water once a week ; in autumn much less ; and, in 

 winter, fifty gallons only onCe a month. As spring advances, 

 a regular increase takes place, till the heat of the weather 

 renders its largest supply necessary. In fine weather, also, 

 at this period, it is sprinkled with the engine every afternoon, 

 and closed up with a strong heat. To produce a constant ex- 

 halation of warm moisture, the paths of the house are copiously 

 watered. The palm grows too luxuriantly, and Mr. Nickson 

 is of opinion, that less heat would not be injurious ; but as 

 there are much tenderer plants iii the same house, it is essen- 

 tia,! to keep the heat regularly up. 



The house is 44 ft. long, 24 ft. broad, and 21 ft. 8 in. in the 

 centre, and the general temperature ranges from 70° to 75^ in 

 summer, and to about 60° in winter. 



This palm has been successively named, by those who have 

 seen it, '^ Corypha umbraculifera, Corypha umbraculifera 

 minor, Corypha minor, and Sdbal Blackhurmdna." The 

 latter, I am led to understand, is its present appellation, as 

 well as being considered the most correct. Of this I will not 

 presume to decide. T. K. Glazebrook.
