Collected by Mr. C. G. Pringle on the mountain sides of Santa Inez del Monte, 
8,500 feet altitude, October 5, 1894 (No. 4997); also by Mr. E. W. Nelson from the 
foothills on the west side of the Valley of Oaxaca, at between 5,500 and 7,500 feet 
altitude, in the lower Sonoran zone, September 20, 1894 (No. 1418), and on mountain 
sides near Tlapancingo, 6,000 to 8,000 feet altitude, in upper Sonoran zone, Decem- 
ber 7, 1894 (No. 2083). , 
This species was first collected by Galeotti some fifty years ago on the Cordillera 
of Oaxaca, and has not been collected sinee until obtained by Messrs. Pringle and 
Nelson. Mr. Pringle, in a letter of March 19, 1895, to Mr. J.N. Rose, writes as fol- 
lows: “As respects Neogoezia, No. 4997, it was found first by Mr. Nelson, then by 
myself more widely scattered, on a range of mountains 25 miles west of Oaxaca, 
which range has an altitude of 9,000 feet and may be regarded as the margin of the 
mountainous tract called the Mixteca Alta, over which runs in « zigzag course the 
continental divide. The plant is abundant on somewhat dry ridges and slopes of 
these mountains, at an elevation of about 8,000 feet, among a sparse growth of oaks 
and pines. Frankly it is my opinion that there is but one species there, though a 
variable one, as the conditions, fertility and humidity of soil and exposure to open 
sunlight, vary. The specimens were all gathered on a tract 2 or 3 miles in extent; 
the fruits which lie in the sheets with flowers (they are scarcely mature enough) 
were gathered at the same time with the tlowers.”

Collected by Mr. C. G. Pringle on mountain sides about Oaxaca, Sierra de San 
Felipe, at an altitude of 9,000 to 10,000 feet, in flower June 29, and at an altitude of 
10,500 feet, in fruit August 25, 1894 (No. 4725); also by Mr. E. W. Nelson on Sierra 
de San Felipe, August 20 to 30, 1894 (No. 1418a). 
Mr. C. G. Pringle sends this interesting note regarding the species: ‘‘It presents 
a rosette of leaves which he close upon the surface of the soil (black humus) in 
little meadows and flats along the creeks of the Sierra de San Felipe, 10,000 feet ele- 
vation. This mountain chain is the continental divide, at whose base on the Pacific 
side, some 10 miles distant from and 5,000 feet below its summit, is located the city 
of Oaxaca. The flowering peduncles of this plant at anthesis rise 1 to 4 or 5 inches 
above the leaves, but in fruit some of them recline on the ground, while others rise 
quite erect.”

Neonelsonia Coult. & Rose, gen.nov. (Smyrniem.) 
Calyx teeth minute. Petals broader than long, with short inflexed tip. Fruit 
broadly ovate-cordate, didymous and beaked, glabrous, with 2-parted carpophore 
and low conical stylopodia bearing short recurved styles. Carpel globose-ovate, 
beaked and incurved, the entire surface divided among five more or less wrinkled 
ridges which bear filiform ribs on the back. Oil-tubes large and solitary in the 
intervals of the ridges, with a small accessory one on each side on the slope of the 
adjoining ridge, 2 to 4 on the very narrow commissural side. Seed section nearly 
circular in outline, strongly indented beneath the large oil-tubes, with a deep and 
narrow sulcus which enlarges more or less into a central cavity.—Low caulescent 
perennials, with ternately compound leaves, no involucre, involucels of elongated 
filiform bractlets, and greenish-yellow flowers. 
This is nearest Smyrnium and Arracacia, but its peculiarities are so marked that it 
does not seem to be closely allied to any genus. 
Named for Mr, E. W. Nelson, the ornithologist, who has also been an indefatigable 
collector of Mexican plants.
