Gardening. PROTEA PROTOPLASM 1439 shows for many successive seasons, is as certain as that they were once the glories of the old flue-heated houses that our forefathers called stoves, in which orchids quickly perished, and Banksias and Proteas throve ; Over 40 colored plates of Proteas have been publiyhed, of which 23 appeared in Andrews' Bot. Rep. between 1797 and 1811. The interest in proteaceous plants is growing in southern California. Proteads have a reputation for being difficult to cultivate away from the Cape, but Hooker's statement seems to indicate that their culture is not so miich difficult as special. Under glass they are said to require a coolhouse which is airy and sunny "The one great danger to cultivated Proteads," Watson, "is excessive watering, and to guard against this it is found to be a good plan, in the case of delicate species, to place the pot in which the plant is grow- ing inside a larger one, filling up the space between with silver sand. The lat- ter is always kept ; Many of the species need staking, as the shoots are quick to break off at the base if unsup- ported. The family Proteacese contains 14 gen- era, of which 10 are typical of southern Africa and 4 of Australia. According to Benthara and Hooker, the family is as dis- tinct as possible and has never been con- fused by any one with anything else. The most popular member of the family for greenhouse culture in America at present is the Silk Oak, or Grevillea. In southern California the interest in the family is now centered on the Silver Tree, Leucaden- dron, which is the characteristic tree about Cape Town and practically the only native tree of any kind growing th
