Neonelsonia ovata Coult. & Rose, sp. nov. PLATE IX. 
Stems 3 to 9 dm. high, glabrous throughout; root leaves large, 3 dm. or more long, 
3-ternate; leaflets often 3-lobed, ovate, acute or acuminate, rounded at base or the 
terminal one with cuneate base, crenate with apiculate teeth, 3.5 to 7.5 cm. long; 
stem leaves more simple; umbels long-peduncled or sessile; rays 3.5 to 10 em. long; 
pedicels 12 to18 mm. long; bractlets of the involucels 18 to 50 mm. long; fruit 4mm. 
high, 7 mm. brozd. 
Collected by Mr. E. W. Nelson 18 miles southwest of the city of Oaxaca, altitude 
7,500 to 9,500 feet, September 10 to 20, 1894 (No. 1585); also by Mr. C. G. Pringle in 
deep moist woods of the Sierra de Clavellinas, 9,000 feet altitude, October 18, 1894 
(No. 6007). 
EXPLANATION OF PLATE.—Fig. a, side view of the fruit, enlarged 4 diameters; b, cross section of 
carpel, enlarged 6 diameters. 
GSnanthe pringlei Coult. & Rose, sp. nov. 
Stems often creeping and rooting at the joints, glabrous, with upright stems 6 to9 
dm. high; leaves twice pinnate, somewhat triangular in outline; leaflets ovate, 
acute, sharply serrate with cuspidate teeth, often with 1 or 2 lateral lobes, 12 to 25 
min. long; peduncles lateral and terminal, 5 to 7.5 em. long; rays of umbel 15 to 20, 
nearly equal, 2.5 em. long or less; pedicels 3mm, long; involucre wanting; involucels 
of several linear bracts oblong, 41mm, long, with thick corky ribs. 
Collected by Mr. C. G. Pringle in cold bogs of the Sierra de Clavellinas, altitude 
9,000 feet, October 25, 1894 (No, 6009). Most resembling our United States species, 
but the leaves have a more dissected appearance, the leatlets are more numerous, 
acute, and sharply cuspidate-serrate, the rays shorter, the fruit not in such dense 
umbels, more corky, making it much larger in cross section. 
This is the first species of (Enanthe described from Mexico, although Mr, Hemsley 
reports (in the Biologia Centrali-Americana) an unnamed species! from near 
Zacoalco. 
Osmorrhiza mexicana Grisebach, Goett. Abh, xxiv, 147 (1879). PLATE X. 
Stems rather slender, 6 to 9dm. high, somewhat hairy; leaves more finely dissected 
than in O. nuda; umbels with few spreading rays; involucre and involucels of linear 
bracts; style and stylopodinm minute, very unlike those of O. brevistylis. Rather 
common in the mountains of Mexico. Generally referred to O. brevistylis by writers 
on Mexican plants, but more resembling O. nuda. 
Collected by Mr. C. G. Pringle on the Sierra de San Felipe, altitude 10,000 feet, 
September 19 and in November, 1894 (No, 5547); also by Mr. E,W. Nelson in the 
Sierra de Clavellinas, September 10 to 20, 1894 (No, 1383), The following specimens 
are also in the National Herbarium: Mr. Henry E. Seaton’s, from Mount Orizaba, 
August 6, 1891 (No. 195); Mr. C. G, Pringle’s, from the State of Mexico, Septem- 
ber 11, 1892 (No. 5208); and M. Bourgeau’s, from the forest of the Desierto Viejo, 
1865-66 (No. 781). , 
A western Cordilleran type seems to extend through North and South America, 
which is O. nuda in the United States, O. mecicana in Mexico, and O. berterii in South 
America. 
We had described and figured this species as new, under the above name, but 
learned before publishing that Grisebach had anticipated us in both description and 
name, and had published the species in his flora of the Argentine tepublic, as cited 
above. He includes in it the already described species from South America, which, 
however, seems to be distinet; but as he evidently takes Schafiner’s Mexican plant 
as his type, his name should be retained as applying to the Mexican species. 
EXPLANATION OF PLATE.—Fig. a, fruit, enlarged 3 diameters; b, cross section of carpel, enlarged 9 
diameters. 
1Mr, Hemsley now considers his plant to be Arracacia multijida Watson.
