Dr. Treub on Javan Vegetation.

Dr. M. Treub, Director of the Royal Botanic Gardens at Buitenzorg, Java, delivered a lecture on "The Vegetation of Java" before the Botanic Club, in the University Museum yesterday afternoon.

The natural vegetation in the forests of Java is wonderful. Palms and ferns grow to enormous sizes, and trees 90 feet high are common occurrences. They grow with great rapidity and by actual measurement bamboo sprouts have been known to grow to 3 feet in 24 hours. The Botanic Gardens, which are under the control of the Dutch government and occupy an area of nearly 1000 acres, have proved very useful because they allow plants to grow in their natural way where they can be studied during the whole year. The observation of hibernating plants is in this way greatly facilitated.
