Gold and Silver Perns are amongst the choicest and 

 most distinct of all ferns in cultivation, by reason of the 

 beautiful golden or silvery powder that covers the backs 

 of the fronds. The best Gold Pern is G. chrysophijlla; 

 the best Silver Fern is G. calomelanos. Unfortunately, 

 however, these fine subjects scarcely thrive anywhere 

 but in a warm conservatory. The finest Gold or Silver 

 Fern will present an unsightly appearance if syringed 

 or watered overhead, as the water carries off the farina. 

 Moreover, many a fine specimen is spoiled by overwatcr- 

 ing at the roots in winter time or directly after repot- 

 ting. The Gold Fern shown on Plate XI, which was 

 considered one of the finest specimens of Gymnogramma 

 ever raised in America, a plant that had been carefully 

 kept for many years, was destroyed one winter by over- 

 watering. In the summer time, when these ferns are 

 growing freely, there is little danger of over-watering, 

 always provided the drainage be thorough. In the winter 

 Gold and Silver Ferns should have a drier atmos- 

 phere, and less water will suffice. Plants in small pots 

 should be lowered into a pail of water. Do not soak 

 them again until they show indications of dryness. 

 Large specimens should never be watered with the'hose ; 

 always use the watering can. A critical time with Gold 

 and Silver Perns is after repotting, and many promis- 

 ing specimens are ruined as a result of premature 

 watering at this time. When the plants are well estab- 

 lished and the roots have taken fresh hold in the new 

 soil they will need more water. 



Gold and Silver Ferns like a drier atmosphere than 

 the majority of ferns, particularly in winter. Hence 

 they should not be placed on low benches. Elevate them 

 in some way so that they can get the warmer and drier 

 air of the conservatory. Young specimens should be 

 placed on shelves oi- brackets near the light. Older 

 plants may be set upon a large inverted pot or fern pan. 

 A plant grown from spores shows its true character 

 early. A year's growth produces fine little ferns, in 2 

 or 3-in. pots, with fronds 4 or 5 in. long, the young ferns 

 being 2 or 3 in. high. Another year's care will give 

 handsome specimens a foot or more high. 



The first thing to do with Gold and Silver Ferns is to 

 give them a special place wliorf tlicv can recrivp special 

 care. For p^.tm,- .■, Ii,l,i hmm ,,,.., ^ ,|,.~ir:,M... In the

 soil for young plants consists of 2 parts peat and

 growth has started. If repotting is delayed too long 

 the young fronds will be injured. Robert Shore.

GYNANDROPSIS (Greek words : the stamens look 

 as if they were borne on the ovary). Cappariddcew. 

 This genus includes a tender annual plant with 5-7 leaf- 

 lets, and flowers resembling the spider flower, or Cleome. 

 It is known to the trade at present as a Cleome, but 

 Gynandropsis is distinguished by having a long torus 

 (or receptacle), which is produced into a slender body 

 (or gynophore) which is elongated at the middle, and 

 bears the pistil to which the filaments are united. 

 Cleome has a short torus, which often has an appendix 

 on the back, .stamens about 6 in Gynandropsis: in
