ZAMIA INTEGBIFOLIA. 



The Jamaica sago tree, as the subject 

 of this note is commonly known, is the 

 only North American representative of 

 a genus that includes some thirty spe- 

 cies, the other members of this group 

 being found in the West Indies, Central 

 and South America, and portions of 

 Africa. 



Zamia integrifolia is quite common 

 in parts of Florida, where it is locally 

 known as "Comptie," and plants of 

 it are frequently found in northern 

 greenhouses, and also used for outdoor 

 decoration during the summer. 



As will be seen from the plant pic- 

 tured, it bears some resemblance to a 

 cycas, to which the zamias are closely 

 related, and has the same stout and 



The stems of the zamias contain much 

 starchy matter, and on this account 

 they are ground up in some parts of 

 the world and the resulting flour made 

 into a kind of sago, from which practice 

 we have the common name, already 

 quoted, of Jamaica sago tree. 



This genus also possesses interest in 

 the fact that it is an ancient one, there 

 having been no less than fifteen species 

 of zamia discovered among the fossil 

 plants that have been unearthed in vari- 

 ous countries. W. H. T. 



THSIPS ON SNAPDBAOONS. 



I am sending you some leaves from 

 my snapdragons and also from-stevia, 

 which are afflicted with a small black 

 bug which has the tendency, when dis-

woody stem, to which are attached a 

 number of rather stiff, pinnate leaves, 

 with narrow leaflets of leathery texture. 

 The manner of growth of the zamias 

 differs from that of the cycas in the 

 fact that the former plants produce 

 their leaves in succession, while the 

 cycas throws up a number of leaves in 

 one growth, thus forming a complete 

 crown of foliage in one operation. 



The stems of the zamias are not in- 

 frequently sent home by collectors in a 

 similar condition to that in which the 

 imported trunks of cycas are received 

 in this country, namely, minus both 

 foliage and roots, and when arriving in 

 this condition should be treated in the* 

 same way as the cycas, being potted 

 into as small pots as may be conve- 

 nient and placed in a warm and slightly 

 shaded greenhouse, syringed regularly 

 and watered enough to keep the soiJ 

 moist without getting it sodden before 

 the plants begin to root. 



Like tlie cycas, these plants do not 

 need frequent repottings, but well es- 

 tablished specimens will be benefited 

 by an occasional watering with liquid 

 manure during the "growing season. 



From the fact that the inflorescence 

 of the zamias is in the form of a cone 

 like that of a pine tree, and that the 

 seeds are found between the scales of 

 the cone, usually in pairs, some botan- 

 ists have concluded that these plants 

 are a sort of connecting link between 

 the palms and the pines, for they com- 

 bine some features' of each. 



turbed, to hop on the leaf. I would like 

 to have you let me know what it is and, 

 also, if there is anything that will de- 

 stroy it. I suppose it can be killed by 

 hydrocyanic acid gas and would like, if 

 possible, to have you give me the for- 

 mula for this and state how much it 

 takes to a cubic foot of space.

The leaves forwarded showed plainly 

 the work of thrips, or hoppers, as they 



are sometimes called, some dead speci- 

 mens of these insects also being en- 

 closed. While you could, no doubt, kill 

 these by using hydrocyanic acid gas, 

 there would be great danger of your 

 seriously damaging the plants at this 

 warm season of the year. Snapdragons 

 in particular ate susceptible to injury 

 from this gas, even a light dose in win- 

 ter, with a short exposure, being suffi- 

 cient to make the tops wilt down even 

 though the leaves themselves may not 

 be scorched. 



iou have kept your plants in too hot 

 and dry an atmosphere. Had the proper 

 amount of moisture been kept and the 

 foliage well syringed, there would have 

 been little chance for thrips to get a 

 foothold. Syringe your plants freely. 

 Use a nicotine solution at first; then 

 use cold water freely. Formulas for the 

 use of hydrocyanic acid gas can be 

 found in manykyback numbers of The 

 Eeview, and this is a good remedy to 

 apply when the weather is cooler.

Vinton, Va. — O. E. Hedges, the lessee 

 of the greenhouses of C. A. Shaffer & 

 Co., at Alexandria, has moved here 

 from that city. 



Houston, Tex. — In order to enlarge 

 the scope of its business, the Henk Dir- 

 ken Floral & Nursery Co. has incorpo- 

 rated and will establish nurseries and 

 greenhouses to carry on a producing 

 as well as a distributing trade. 



Cumberland, Md. — G. Frank Lippold 

 has sold his florists' plant and retired 

 from business. He disposed of his 

 stock of bedding plants at retail. The 

 greenhouses, containing 10,000 feet of 

 glass, are being torn down and the land 

 will be sold for building lots.
