22 GUAM AGRICULTURAL EXPERIMENT STATION. 



cxtcjisive to render it of any great importance to the beekeeper. Corn 

 is sometimes visited by bees in large numbers, but it is probable that 

 they are attracted largely for the pollen which this plant provides. 

 The Ceara rubber tree (Manihot glaziovii) would seem to be a heavy 

 yiclder of honey from observations taken on a single specimen tree at 

 this station. The tree flowers for a period covering several months 

 in the year and during clear weather while the flowers are open great 

 numbers of bees swarm about the tree collecting honey. This tree has 

 flowered at the station in 15 months from the time the seeds were 

 planted. The "camachili " {PitJiecolohium dulce) is also visited by bees 

 under certain conditions. This tree is common on the island and 

 jflowers during the dry season when the honey flow is light. During the 

 past year trees at the station have borne a mass of flowers throughout 

 a long season. These trees have been constantly under observation 

 Ax-ith relation to their attraction for the honeybee, and the latter has 

 been found working on them only a few times during the entire season 

 and only in the early morning hours. The kapok tree {Ceiba pentandra) 

 is also a good honey-yielding plant. It flowers during the early part 

 of the dry season. This tree does not bear a profusion of bloom. 

 "Siempre viva" is the native name for a small decumbent plant 

 (CommeliTia nudijlora) bearing a light-blue flower wliich is visited by 

 bees in large numbei-s dm-ing the early morjiing hours. In Guam this 

 plant springs up during the wet season and blooms during the months 

 of September, October, and November.
