third, there are several forms growing in that region that without 

 accurate comparison would be referred to this species. 



The only specimen I have seen from the United States was 

 collected near Los Angeles, Cal., by Dr. A. Davidson (U. S. Nat. 

 Herb Sheet, 25096). The plant, which is sterile, apparently be- 

 longs to var. annuliferum Milde and may be characterized as fol- 

 lows : Cespitose, 4-10 inches high; 8-10 angled; ridges very 

 rough, with cross-bands of silex, the grooves with 1-2 lines of 

 stomata in a series, and with rosulae in bands or scattered ; 

 branches near base, few and short; sheaths green, long, ampli- 

 ated, keeled below ; grooved in center near tip. Teeth brown 

 centrally, the persistent bases fading and becoming papery. 



E. Funstoni, Sp. Nov. 



For several years there has been collected and distributed 

 from Southern California a peculiar Equisetum, under the name 

 of B. Mexicanum Milde. This name was given by Milde to a 

 fragment 15 inches long in Herb. Monacense, collected in Mexico 

 by Karwinski. Later he reduced this to a form of ramosissimum 

 and (Mon. 504) transferred the name to an entirely different 

 thing related to giganteum if not identical as Baker holds. As the 

 plant in hand does not agree with either description I have pro- 

 posed to name it Funstoni as commemorative of the time when the 

 distinguished General was as active in botanical as he now is in 

 military affairs. 



Plant of various aspect ; a few inches to two and one-half feet 

 high, prostrate or erect, 1 to 5 lines in diameter, naked or 

 branched, mostly very rough, especially the smaller stems, 10-30 

 ribbed. Ridges with many transverse thin, usually much elevated 

 bands of silex, the grooves with short bands and points. Stomata 

 single or double rowed. Sheaths elongated, moderately ampliated, 

 usually incurved at limb, ridged in the center through nearly the 

 entire length, becoming flat above, the edges rising into ridges or 

 in smaller stems rounded, concolorous with the stem black or 

 brown in various degrees, often fading to white, rarely with a 

 basal black ring. Teeth membranous, often cohering and pushed 

 off by the growth of the stem, like a candle-extinguisher as in 

 most hiemale varieties, leaving a long or small persistent, black,
