agrees* well with the original description. It therefore seems best to 

 regard B. Pringlei^ Wats., as synonymous with B. comosa, Nees. 



To this species also may be referred Dr. Coulter's no. 1193; and 

 Priiigle's plant, collected in Tamasopa Canon, State of Sun Luis Potosi, 

 10 June, 1890, no. 3074, distributed as B. Pringlei, Wats. 



Beloperoiie Nelsonii. Erect: stems branching, subterete, covered 

 with a spi'eading or slightly reflexed grayish pubescence : leaves ovate- 

 lanceolate or oblong-lanceolate, 5 to 10 cm. long, 2 to 4 cm. broad, 

 obtuse at the apex, entire, narrowed below into a slender petiole, densely 

 lineolate above, pubescent on either surface, especially on the veins, 

 later becoming glabrous; petioles about 2 cm. in length: inflorescence 

 terminating the stem and branches in rather close bracteate spikes : 

 bracts oblong or obovate : bracteoles linear, nearly 1 cm. long, exceeding 

 the calyx : calyx about § mm. long, deeply 5-parted ; divisions nearly 

 equal, lanceolate, acute, ciliate : corolla 2 to 2.5 cm. long; tube exceed- 

 ing the limb ; upper lip shortly 24obed, the lower more deeply 3-lobed, 

 rather broad, somewhat plaited in the throat: capsule 10 to 12 mm. 

 long, pubescent. — Collected by E. W. Nelson on Maria Madre Island 

 of the Tres Marias group of islands, 3-25 May, 1897, no. 4246. 



A species closely resembling B. comosa, Nees, but with a much 

 shorter corolla, and broader lower lip. The leaves are also somewhat 

 larger, longer petioled and much less pubescent. It may be that further 

 material will prove this to be a variety of B. comosa^ Nees, but, as the 

 material at hand shows no sign of intergradation. it seems best for the 

 present at least to regard Mr. Nelson's plant as a distinct species. 



PORTLANDiA PTEROSPERMA, Wats. Proc. Am. Acad. xxiv. 52. Ex- 

 cellent fruiting speciwiens were collected by Mr. E. W. Nelson on 

 Maria Madre Island, 3-25 May, 1897, no. 4211, but for the slightly 

 thicker leaves, correspond accurately with the type of the above sj^ecies, 

 Mr. Nelson's specimens show well the oblong-obovoid longitudinally 

 ribbed and conspicuously lenticulated septicidally dehiscent (2.5 cm. long) 

 capsule. 



Machaonia floribunda. Shrub or small tree, 3 to 5 m. high : 

 branches covered with a reddish brown bark, and dotted with numerous 

 small lenticels : the ultimate branches finely pubescent : leaves petiolate, 

 ovate to ovate-lanceolate, 2 to 5 cm. long, 1 to 2 cm. broad, acuminate, 

 acute, entire, ciliate-scabrous, narrowed below into a pubescent petiole 

 (2 to 5 mm. long), glabrous or jiuberulent on the upper surface, below 

 glabrous except on the midrib toward the base: stipules (1 or 2) linear- 

 subulate, 2 to 3 mm. long : inflorescence of compound many flowered
