Il modo di crescita del zamias differisce da quella della cycas nel fatto che l'ex piante producono le loro foglie in successione, mentre la cycas genera un certo numero di foglie in una crescita, formando così una completa corona di fogliame in una sola operazione. Gli steli del zamias non sono spesso inviati a casa da collezionisti in una condizione analoga a quella in cui il trunk importati di cicadee sono ricevuti in questo

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. J. L. M. 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
