March, 1900. Plantve Utowan^e Millspaugh. 23 



Anemia Wrightii Baker Syn. Fil. 435. 



On limestone boulders (coraline) in open woods, center of the 

 island, Cozumel (1564). 



The specimens are excellent examples of this very slender fertile- 

 fronded dimorphous Anemia, the sterile fronds of which might be 

 mistaken for a delicate form of A. adiantifolia. 



CYCADACE.E. 



Zamia Allison-Armourii sp. nov. 



Rootstalk semifusiform, amylacious, 20 cm. long, 3-5 cm. in 

 diameter; leaves, 5, palmose, 75 cm. long; petioles glabrous through- 

 out, trisulcate from the base; leaflets all alternate, 16 jugal, broadly 

 linear-lanceolate, narrowed at the base, round-pointed and slightly 

 sharp-serrate at the apex, not falcate, prominently and distinctly 26- 

 veined, the median 18-20 cm. long, i. 3-1.5 cm. broad, the basal and 

 apical leaflets 16 cm. long, 1.3 cm. broad, somewhat more promi- 

 nently serrate, the margins not revolute. Male strobiles in anthesis 9 

 cm. long, 1.5 cm. diameter, cylindrical acute at the base and apex; 

 peduncle 5 cm. densely rusty tomentose; peltae transversely ovate, 

 rusty tomentose, 5x4 mm. arranged in 9 longitudinal rows. Type 

 in Field Col. Mus. Herb. No. 60817. 



Near Z. augustifolia and Z. Portoricensis Urb. Syll. Antill. 291, 

 but differing entirely in general and special habit. The nearest speci- 

 men of Z. augustifolia is Wright's Cuban 1463, the leaflets of which 

 are sub-falcate 13 x 1.8 cm., more or less 30-veined, the veins indis- 

 tinct, leaf sharply serrate from near the middle. 



Shady, moist banks of streams inland from San Domingo City 

 (817). The rootstocks are gathered, boiled and eaten by the natives, 

 who, however, have as yet made no attempt to cultivate the species. 



PINACE.E. 



Juniperus Bermudiana Linn. Sp. PI. 1039. 



Throughout the Bermuda Islands. Hamilton, Paget's (4) and 

 the bay islets (13) in full fruit. Notwithstanding the excellently dif- 

 ferentiative treatment of this species by Dr. Maxwell T. Masters in 

 Jour. Bot. 1899:1, I cannot specifically separate it from J. Virginiana 

 Linn., though, in the absence of fuller specimens, I deem it best to 

 retain the more local name. The differences shown by my fruiting 

 specimens from many American coast specimens of Virginiana might 

 well be due to environmental causes. 



TYPHACE.E. 



Tvpha Domingensis (Pers.) Kunth, Enum. 3. 



T. angustifolia Domingensis Pers. Margin of lagoon south of 

 Progreso, Yucatan (1676), female spadix 14.5 x 1 cm., interspace 5.3 

 cm.; male spadix 24.5 cm., leaves 1 m. x .6 cm. 



ALISMACEiE. 



Sagittaria lancifolia Linn. Syst. ed x: 1270.
