According to my observations the following trees form a large part 

 of the vegetation of one of the sinks: Celtis mississippiensis. Citrus 

 limonium, Ficus carica, Musa Cavendishii (planted), Mclia azederach, 

 Laniana camara, L.involucrata, while Stenotaphrum americanum abounds 

 and Asplenium trichomanes together with Rhus toxicodendron are found 

 on the sloping sides of such depressions. Two vines are abundant and 

 loop themselves across the trees, viz., Cardiospermum halicacabum and 

 Jasminum gracile. Commelina agraria { = nudiflora) also occurs in such 

 sinks. 



At Walsingham, Juniperus hermudiana prevails mixed with 8abal 

 Blackburniana, Celtis mississippiensis, Citharexylum quadrangidare, 

 Calophyllum calaha, etc., while the trees are festooned with Jasminum 

 gracile, Rhus toxicodendron and Ipomoza purpurea. Peperomia oh- 

 tusifolia and several ferns are found on the rough rocks in the bottom 

 of the sinks, together with Bryophyllum calycinum and one or two spe- 

 cies of Lantana. Citrus limonium and Musa Cavendishii are also 

 present in this jungle of plants. 



Scrub Formation. 

 This formation is due to the hand of man. After the cedars are cut 

 down, if the land is neglected and allowed to stand without cultiva- 

 tion it is covered by a growth of several species of Lantana, L. camara 

 and L. involucrata. Bryophyllum calycinum also abounds together 

 with many introduced weeds and thickets of Nerium oleander. Many 

 of the hillsides in Bermuda are covered with this worthless scrub. 

 Later perhaps under favorable conditions Juniperus hermudiana appears, 

 but the flora is never restored to its original condition because the sage 

 bush plants always form an important constituent of the undergrowth.
