7, dehiscing by terminal pores, glabrous; ovary pubescent; legume (immature) becom- 

 ing glabrate, 12.5 to 15 cm. long, 6 to 8 mm. wide, strongly flattened, articulated; 

 stipe 10 mm. long. 



Collected by E. W. Nelson between San Geronimo and La Venta, State of Oaxaca, 

 July 13, 1895 (No. 2783), and also along road from Ocuilapa to Tuxtla, State of Chia- 

 pas, altitude 2,100 to 3,000 feet, August 29, 1895 (No. 3069) ; also by Mr. C. G. Pringle 

 on lava beds near Cuernavaca, June 23, 1896 (No. 6340). 



This species must be near the Brazilian C. hypoleuca Mart. 

 Cologania procumbens Kunth, Mimoses, 205, t. 57. 1819. 



Collected by Mr. E. W.Nelson between Gnichocovi and Lagnnas, State of Oaxaca, 

 altitude 187 to 289 meters, June 27, 1896 (No. 2750). 



We have the following other specimens in the National Herbarium from Guate- 

 mala : Enrique Th. Heyde's Nos. 131 and 582. 1892 ; 1 1. von Tiirckheim's No. 11 19 ( 1888), 

 from Santa Rosa, and W. C. Shannon's No. 4705 from. Department of Guatemala, all 

 in John Donnell Smith's distributions, in which the last two were sent out as CaUc- 

 Ua marginalia, detenu. Micheli. 



Pringle's No. 4401 (1893) from Jalisco, also referred to the above, seems to belong to 

 another species, differing from C. procumlens in that the pubescence of stem and 

 petiole is erect instead of retlexed, the leaves much more elongated, and the flowers 

 smaller. The species appears to be new and I would name and characterize it as 

 below. 

 Cologania erecta Rose, sp. nov. 



Stems from a woody base, erect, 7.5 to 15 cm. high, with rather close, erect pubes- 

 cence; leaflets elongated, 10 to 15 cm. long, 4 to 8 mm. wide, rounded at base, some- 

 what tapering toward apex, but with obtuse apiculate tip; calyx 4 mm. long; pod 

 2.5 to 3.7 cm. long, 3 mm. wide, pubescent. 



Collected by Mr. C. G. l'ringle on rocky hills near Guadalajara, June 21, 1893 

 (No. 4401). 

 Combretum palmeri Rose, sp. nov. 



A high-climbing woody vine; branchlets opposite or alternate, clothed with a 

 short velvety pubescence, subtended by short straight spines; leaves opposite, 

 oblong, obtuse, truncate or rounded at base, 5 to 6.2 cm. long, glabrous above, paler 

 and pubescent beneath, especially along the veins, becoming glabrate ; petioles short 

 but distinct; inflorescence paniculate, more or less pubescent; spikes slender, 

 loosely flowered; brads setaceous shorter than the glabrous ovary ; calyx turbinate, 

 glabrous without, 5-toothod, thin; teeth shorter than the tube; petals "white" or 

 yellow, short, oblong, 2 mm. long, obtuse, inserted at the top of calyx tube, alter- 

 nate with the lobes; Btamens 10, long-exserted, glabrous; 5 inserted with the petals, 

 5 near the middle of the calyx tube; ovary 1-celled, 5 to 8-ovuled; fruit 1-seeded, 

 12 mm. long, with 5 thin equal wings. 



Very common in bottom lands; collected by Dr. Edward Palmer near Acapulco. 

 February, 1895 (No. 396). 



This species differs from all our American species in being thorny. Dr. Calmer 

 states that it grows over the tallest trees about Acapulco, and that the flowers are 

 white and as sweet-scented as apple blossoms. 



Crotalaria filifolia Rose, sp. nov. Plate XIV. 



Perhaps annual, 6 to 12 dm. high, usually several steins in a clump, somewhat 

 branching above, green and nearly glabrous; leaves on petioles 12 to 18 mm. long; 

 stipules small; leaflets 3, linear, elongated, 2.5 to 5 cm. long, acute, slightly pubes- 

 cent; racemes slender, few-flowered (6 to 15), opposite the leaves and much longer 

 (10 to 20 cm. long); bracts small, linear; pedicels slender, 6 to 8 mm. long, at first 

 erect, but reflexed in fruit; sepals narrow, acute, 4 mm. long; corolla small, yellow 

 often tinged with purple ; banner orbicular ; keel strongly curved, acuminate, margins 

 . shghtiy ciliate ; wings much shorter than the keel, obtuse, ciliate on margins; imma-
