EXPLANATION OF PLATE XII 



Fig. 1. The avenue of talipot palms, Corypha umbraculifera, in the Peradeniya 

 Gardens, Ceylon, in December, 1920. Seven of the sixteen palms forming the avenue 

 flowered in June, 1918. One of the palms which had flowered stands in the front on the right 

 side of the picture. The fruit has fallen, leaving only the bare stalks of the inflorescence. 



Fig. 2. Another Corypha in the Peradeniya Gardens which flowered some years be- 

 fore those shown in figure 1, and which, unlike those palms, received for at least four years 

 previous to the time of flowering an annual rainfall above the average normal. This 

 picture gives some idea of the luxuriance of the inflorescence. (The photograph is published 

 through the courtesy of Plate, Ltd., Ceylon.) 



Fig. 3. A telephotograph of the crown of a Corypha umbraculifera, after fruiting, in 

 the Buitenzorg Gardens. This talipot palm had never experienced a drought; indeed, it 

 was drenched in rain nearly every afternoon of its life, while those palms shown in figures 

 1 and 2 were annually subjected to a dry season which frequently assumed the proportions 

 of a drought. Some few of the leaves of the former crown of foliage are still to be seen 

 clinging to the trunk. The palm is dead, or nearly so. 



Fig. 4. A small clump of Dendrocalamus giganteus in full flower in the Buitenzorg 

 Gardens. Long pendent inflorescences are abundant, while but few leaves remain on the now 

 nearly dead culms. These bamboo shoots were taken from an old clump of D. giganteus 

 which was beginning to flower. The "young" transplanted culms flowered soon after the 

 parent plant.
