Chamaesaracha physaloides. — Annual (?), glabrous, stem! ap- 

 parently a foot or two high, with spreading, slightly wing-angled 

 branches; leaves ovate, an inch or more long, the^ lower nearly 

 entire, the upper with coarsely sinuate-toothed margins; flowers on 

 slender pedicels nearly two inches long; calyx small, and, with the 

 upper portion of the pedicel, puberulent with minute, flat, scale-like 

 hairs ; corolla cream-colored, f inch broad ; fruit unknown. 



Collected in the Patagonia Mountains of the southern part of 

 Arizona in the month of August, 1881, by Mr. S. P. Buckminster, 

 in a single branch only, which shows a true Chamaesaracha^ as to 

 calyx and corolla, .with the general aspect of an annual Physalis, 



HOLOZONIA, Gen. nov. 



Head heterogamous, with 6-8 pistillate, fertile rays, and about 

 16-20 hermaphrodite but sterile disk-flowers. Involucre of as 

 many herbaceous scales as there are ray flowers, each scale com- 

 pletely and closely enfolding its obovate-oblong, obcompressed, 

 smooth akene. Receptacle small, flat, its chaff united into a 

 tubular, io-12-toothed cup enclosing the disk-flowers. Corollas 

 white ; those of the ray purple-tinted, deeply cleft into 3 linear 

 divisions, open during the whole day; those of the disk 5-lobed, 

 Pappus of the ray a hyaline, saucer-shaped, entire crown ; of 

 the disk, a pair of extremely slender, deciduous scales, which equal 

 the corollas. 



A Californian herb, between Hcmizotiia and Lagophylla^ but 

 of very distinct generic type, with the aspect of the former, and 

 the obcompressed, completely enfolded ray-akenes of the latter, but 

 differing from it by its perennial root, its united chaff, and especially 

 by the remarkable pappus of both ray- and disk-akenes.

Bound. loi. Bot. Cal. i, 367.) — The plant has been long known in 

 a very imperfect way. It is not in the least strange that the author 

 of the Botany of Capt. Beechey's Voyage should have placed it in 

 Hemizonia^ for its whole aspect is so extremely like Hemizonia 

 luzulaefoliay with which it grows, that the present writer, at first 

 sight, passed it by for a mere slender form of that species. Dr. 

 Gray, before the fruit was known, transferred it to Lagophylla 

 on the strength of the complete enclosure of the ray-akenes by the 

 involucral scales ; but that is its only point of contact with that 

 genus. It has still the chaffy cup of Euhemizonia, as also its nu- 

 merous white flowers. 



But, while the character of its akenes forbids its admission to 

 He^nizonia^ its perennial, rhizomatous root, and very singular pappus 

 as certainly exclude it from Lagophylla. The first specimens of this 

 rare plant, showing mature akenes, and exhibiting the unexpected 

 character of the root, were collected by the writer, in October, 1881, 

 almost within the limits of the village of Napa. The above generic 

 character is drawn from these specimens, supplemented by others 

 which came, this year, from the vicinity, of the Napa Soda Springs. 



The character of Lagophylla is strengthened by this plant's re-
