NOTES ON THE FLORA OF THE BERMUDAS. 



BY STEWARDSON BROWN. 



The present flora of the Bermudas, aside from the plants known 

 to have been introduced through the agency of man, probably num- 

 bers about two hundred species, of which thirteen vascular forms are 

 endemic, and has undoubtedly been derived through the usual agencies 

 producing insular floras. On the stretches of sandy beach the same 

 species are met with as characterize similar locations in the West 

 Indies or Florida: Ipomcca pes-capro3 (L.) Sweet, Canavalia obtusifolia 

 (L.) D. C, Sesuvium portulacastrumL., Croton punctatus Jacq., Scccvola 

 Plumieri (L.) Vahl. and Cakile lanceolata (Willd.) 0. E. Schultz, while 

 on the rocky shores are Borrichia arborescens (L.) DC, B. frutescens 

 (L.) DC, Chamcesyce buxifolia (Lam.) Small, and the two characteristic 

 shrubs Suriana maritima L. and Tournefortia gnaphalodes (L.) R. Br. 

 On the shores of the quiet bays and lagoons the mangrove Rhizo- 

 phora mangle L. and Avicennia nitida Jacq. are the dominant species, 

 while in the marshes Osmunda spectabilis Willd., 0. cinnamomea L., 

 Pteridium caudatum (L.) Maxon, Cladium jamaicense Crantz, Eleo- 

 charis interstincta (Vahl.) R. and S., Kyllinga brevifolia Rottb., Typha 

 angustifolia L., Myrica cerifera L. and B acchar is glomeruli} olia Pers. 

 are more or less generally distributed. The plants of the higher 

 ground seem more restricted in their distribution for the most part. 

 Dodonosa angustifolia Sw. is generally distributed through the hills, 

 Randia aculeata L. is known only on the Paget Sand Hills, while the 

 following are found almost exclusively in the Walsingham Tract: 

 Adelia segregata (Jacq.) Kuntze. Psychotria undata Jacq., Trema 

 Lamarkiana (R. and S.) Blume, Eugenia monticola D. C and Zanthoxy- 

 lum flavum Vahl., the last known only from two trees, one on a hill 

 east of Paynter's Vale (B. and B., No. 357, 1905), with several young 

 ones surrounding it, and the other discovered by the writer in one of 

 the sinkholes near the caves at Walsingham. These, so far as known, 

 are all that survive of the "yellow-wood" of the islands, referred to 

 by early writers as growing in such abundance. 



With the exception of the cedar (Juniperus bermudiana L.), which 

 is very abundant in the islands, by far the commonest plants to-day 

 are those introduced by man. A number of weeds on the roadsides
