 toothed at the obtuse apex, the pairs separated 0.5-2 cm.; peduncles stout, 

 villous-pubeseent, 5-10 cm. long; male cone oblong, 5-8 cm. long, 2-2.5 cm. 

 thick, its scales tomentose, broader than high or the lower nearly equally broad 

 and long; ripe female cone ellipsoid, 7-11 cm. long, 5-8 cmi. thick, short-tipped,

2. Zamia angustlfblla Jacq. Coll. 3: 263. 1789. 



Caudex slender, 2 dm. long or longer, completely buried in sand. Basal 

 scales broadly ovate to ovate-lanceolate, acuminate, densely villous 3-5 cm. 

 long; leaves 2-10 dm. long; leaflets 5-20 pairs, narrowly linear, entire or with 

 a few callous teeth at the obtuse apex, 5-20 em. long, 3-6 mm. wide, nearly par- 

 allel-margined or slightly tapering to both ends, shining, the pairs distant, 

 those of larger leaves about 2 cm. apart; peduncles villous, those of male cones 

 5-8 cm. long, those of female cones stouter; male cone oblong-eylindric, 5-7 

 cm. long, about 2 em', thick, pointed, its scales oblong, or rotund, hexagonal, 

 tomentose, 6-7 mm. wide, 3-5 mm. high; ripe pistillate cone 8^9 cm. long, 

 about 5 cm. thick, stout-tipped, its scales 2-2.5 cm. wide, about 1.5 cm. high; 

 seeds 2 cmi. long, red. 



In white calcareous sand, E'lenthera : — Cuba. Naebow-lbaved Bay-eush. 



3. Zamia tenuis Willd. Sp. PI. 4: 846. 1806. 



Caudex unknown definitely. Leaves 6 dm. long or longer; leaflets 40 or 

 fewer, narrowly linear, 7-17 em. long, 6-7 mm. wide at or below the middle, 

 tapering to the obtuse, callously 1-several-toothed apex, the pairs separated by 

 1.5 cm. or less; peduncles pubescent; male cone cyliudric, its scales described 

 as subquadrate-hexagonal, tomentose, little broader than high. 



Bahamas, according to Willdenow and subsequent authors. A leaf from a New 

 Providence plant, communicated by Hon. H. A. Brook, is tentatively referred to this 

 species. A specimen from near Ntievltas, Cuba (Shafer 793), is also referred to it 

 with hesitation. A leaf of the type specimen is figured by Miguel (Linneae 19 : pi. 6) . 

 The species may not be distinct from Z. migusUfoUa. 



4. Zamia lucay§,na Brittou, Bull. N. Y. Bot. Gard. 5: 311. 1907. 



Caudex stout, subfusiform, about 3 dm. long, 1 dm. thick, two thirds buried 

 in the ground. Leaves glabrous, about 1 m. long; petiole obtusely angled, 3-4 

 dm. long ; rachis somewhat angled ; leaflets about 14 on each side of the rachis, 

 spreading nearly at right angles, 17-21 cm. long, 2-2.7 cm. wide, 4^5 cm. apart, 

 linear-oblong, obtuse, or irregularly rounded or subtruncate, and finely sparingly
