534 Cook : A Synopsis of the 



scribed as closely similar to those of Sabal Adansoni. Sargent's 

 5. Mexicana from southern Texas, in addition to the seven times 

 greater thickness of the trunk, has a seed nearly 1.25 cm. broad 

 with a strongly prominent micropyle. There can be little doubt 

 that it is another new species, quite distinct from that of Puerto 

 Rico, similar only in the unusual diameter of the trunk, which is 

 furthermore described as bright reddish brown instead of white or 

 very light grayish as Inodes causiarum. In the view of the ap- 

 parently localized distribution of the species of this genus the 

 name Inodes Texana would be appropriate for that described and 

 figured by Sargent as noted above. 



In addition to the recently described Inodes Uresana [Sabal 

 Uresana Trelease, Rep. Mo. Bot. Gard. 12 : 79), there is another 

 large-seeded Inodes on the western slope of Mexico, a specimen of 

 which was collected at Acaponeta, State of Tepic (no. 1528) 

 by Dr. J. N. Rose,* for whom this species may be named Inodes 

 Rosei. The seeds are of the same size and shape as those of /. 

 Uresana, but have the surface much more finely rugose, or nearly 

 smooth, with the embryo directly lateral, not subdorsal. The 

 branches of the inflorescence are slender and but little over 1 mm. 

 in diameter instead of fusiform and thickened in the middle to 

 nearly 3 mm. as shown in Professor Trelease's photographic illus- 

 tration. 



THRINAX Linn. f. ; Swartz, Prod. Veg. Ind. Occ. 51. 1788 



In the genus Tkrinax were formerly placed all the West Indian 

 fan-palms with smooth stems and no midribs, but the gradual dis- 



* Dr. Rose also kindly permits the use of the following field notes and measurements 

 showing that Inodes Rosei is also a taller and more slender tree than /. Uresana. 



" Trees 6-12 or sometimes even 18 meters high, the long slender naked trunk 15-20 

 cm. in diameter, crowned with a large cluster of leaves ; petioles 60 cm. or more long, 

 flat on the face, pubescent, but becoming glabrate ; blade pale green, 8 cm. or more in 

 width, strongly keeled, more or less clothed beneath with brown scales on the large 

 veins ; segments cleft to below the middle, 25 mm. or less wide ; inflorescence in large 

 branching panicles 60 cm. or more long; fruit spherical, 18 mm. in diameter, blackish 

 or dark blue when mature." 



" A very common tree east of Rosario towards Mazatlan, also extending all the way 

 from Rosario to Acaponeta ; especially common on the low hills, and east of Rosario 

 toward the mountains. This species is of considerable economic importance, the trunks 

 being used in building fences, corrals and huts, while the leaves appear as thatch on a 

 majority of the houses of this region."
