FURTHER STUDIES OF BADIERA DC. 

 Since the publication of my former paper on this genus (Bull. 

 Torrey Club 37: 360-363. 1910), additional specimens which 

 have come to hand afford the following notes and descriptions. 



I. Badiera Penaea (L.) DC. 

 Professor Urban has informed me that my opinion that this 

 is identical with Badiera domingensis (Jacq.) DC. is correct, 

 although he has distributed Santo Domingo specimens under the 

 name B. domingensis. 



la. Badiera portoricensis sp. nov. 



A tree up to 6 m. high, the trunk sometimes 1.5 m. in diameter, 

 the slender branches ascending, the young twigs appressed- 

 pubescent. Leaves subcoriaceous, obovate, 3 cm. long or less, 

 7-15 mm. wide, bright green and shining above, paler and rather 

 dull green beneath, both surfaces with short, scattered hairs when 

 young, becoming glabrate above, the midvein slightly impressed 

 above, rather prominent beneath, the lateral veins few, distant, 

 obscure, the apex rounded or obtuse, the base narrowed or cuneate, 

 the pubescent petioles 1-2.5 mm. long; inflorescence few-several- 

 flowered, 4-6 mm. long; bracts ovate or ovate-lanceolate, acute, 

 pubescent, 0.5 mm. long; pedicels appressed-pubescent, 1.5-2.5 

 mm. long; sepals broadly ovate, obtuse, ciliolate, the larger about 

 I mm. long; petals white; keel appressed-pubescent, 2 mm. long, 

 narrowed below; fruit about 6 mm. wide, about 5 mm. high, 

 finely pubescent, narrowly margined, notched at the apex, sub- 

 truncate at the base, its stipe about 0.6 mm. long. 



Rocky slopes and hillsides, western Porto Rico, especially 

 on serpentine, from sea-level to 700 m. altitude. Type collected 

 at Guanajibo, near Mayaguez {Britton, Cowell & Brown 4349)- 

 Recorded by Bello from my type locality as B. domingensis DC. 

 [Polygala domingensis Jacq.; B. Penaea (L.) DC] of Hispaniola, 

 to which species it is nearest related, but which differs in pilose- 

 pubescent twigs, rather densely pubescent leaves, and much more 

 pubescent, shorter-pedicelled flowers.
