Until recently Middle Florida in my mind was either that portion of the peninsula included between lines projected westward to the Gulf coast from Saint Augustine and Cape Canaverel, or the somewhat larger territory that the 27th and 30th degrees of North latitude would confine. This belief was held without investigation and I now find it to have been quite an incorrect one. Middle Florida, the M. F. of Chapman's Flora of the Southern States, has the Suwanee and Appalachi-cola rivers as its east and west boundary lines. These rivers flow southwardly from Georgia to the Gulf, enclosing nine entire counties and the capital of the State. The section of the State west of the Appalachicola is West Florida, and that eastward of the Suwanee, and continuing to the Atlantic coast, East Florida. These three divisions together would form North Florida, a term that is not, however, to be found in the work noticed above.

There is also a South Florida, the most frequently mentioned of the four sections, but where it touches upon the division north of it, I cannot from Chapman determine with certainty.

Upon the island of Santa Anastasia, the seaward wall of the harbor of Saint Augustine, there are two shrubs of the order Rhamnaceae to be found growing, called botanically, Colubrina Americana and Rhamnidium revolutum, and which are said by Chapman to belong to South Florida. For the benefit of those hereafter to use the Chapman volume it would be well to discover whether these buck-thornish shrubs, and perhaps others, are within or without their proper district. If within it they must be at its extreme Northeast corner and might be looked for, and possibly found, still further up the coast.

A third member of the Buckthorn family on the island is the rigid branched Sageretia Michauxii. This shrub has equally rigid spine-like branch-lets which grow at right angles to their supports. Such of these branchlets as bear flower spikes are from three to four inches in length, whilst the leaf-bearers are from one to two inches and beneath or below the others.

The nearly ovate, small, shining, acute, finely serrate and persistent leaves of the principal stem or stems, are oppositely set, whilst the leaf and spike covered branchlets occur alternately. The plant is a sand and coast lover and grows as far northward as North Carolina. It would make an aggravating little hedge, spreading low and broadly as it does, or a first-rate dog, cat and chicken proof section to a fence of barbed wire which would be impassable by man and cattle above. Florida nurserymen should look it up. The Rhamnidium has stiff gray branches and branchlets with small oval-oblong leaves that have distinctly revolute edges. The leaves of Colubrina Americana are thick, longish, dark green and shining above with a white woolly or rust colored surface below. At base these leaves are wedge-shaped and at apex obtuse and mucronate. The shrub is grayish throughout - has that general look - and would with No. 2 appear well and do serviceable work as a protec ting and ornamental wall to a Florida garden.
