under three aspects as follows: (a) brachycladon, Doell. Ver- 

 ticils few, usually of few short erect branches in the upper part 

 of the 8-1 1 angled stem. Open pools and bogs, in rather firm 

 soil, (b) Icptocladon, Doell. The largest form of the species, 

 usually growing in deep swamps in a few inches of water, btems 

 3-5 feet high, naked for 1 or 2 feet, the lower internodes without 

 stomata, yellowish or flesh-pink, bearing 12-15 regular verticils 

 of branches 3-8 inches long, those of the middle verticil longest, 

 the sterile stem with a long naked tip, the fertile bearing a sessile 

 spike that matures after the branches have developed, (c) At- 

 tentat urn, Milde. Like sterile of a and b, but bearing a small 

 spike at the tip of the long naked portion. A partial transition of 

 the sterile stem. 



5. P olystachyum, Bruck. Like No. 4, but upper branches 

 ending in small spikelets. A late form that is apparently quite 

 rare. I have seen but one specimen, collected by Flett at Ta- 

 coma, Wash. 



MONSTROSITIES. 



Of these I have seen three ; two of the fertile and one of the 

 sterile stem. (1) ProMferum, Milde. Spike bearing a few 

 naked internodes at top. The sterile tip is at times 2-3 inches 

 long. Quite uncommon, an acre rarely yielding more than a 

 dozen. (2) Distachyum Milde. Bearing two spikes in series, 

 with a short internode between. Rare. (3) Monstro-spiralis, 

 This is a form that has been found in several of our native 

 Equiseta and in some Hippochaetae I have seen it in ar- 

 vense, Utorale paiustre, and hiemale. Sheaths continuous for 

 some distance, encircling the stem in a spiral.

GEORGIA FERNS. 



By B. D. Gilbert. 



The past winter and spring were unusually cold in the South 

 as well as the North, and vegetation was delayed a week or ten 

 days longer than common. Consequently when I went out into 

 the country around Savannah, Oa., on April 4, the ferns were 

 only just beginning to be distinguishable. The woods about 

 there are chiefly composed of water oaks and short-leaved pines.
