i 



long as the lobes ; corolla broadly campanulato, slightly exceeding the calyx ov some- 

 times shorter; internal scales none; filaments about as long as the corolla tubes; 

 anthers ovate; ovary globular-ovate, hispid; stigmas sessile; capsule depressed, and 

 just before dehiscence slightly compressed; seeds 4, globular, 1.5 to 2 mm. in diame- 

 ter, pale brown, with few or no pits, sparingly scaly and with a conspicuous but 

 deciduous caruncie. 



Type specimen in the United States National Herbarium, No. 1671, Death Valley 

 Expedition; collected August 21, 1891, in Whitney Meadows, Sierra Nevada, Tulare 

 County, California, by Frederick V. Coville. 



The plant most nearly resembles N. parviftora, but it is readily distinguished from 

 that species by the shapo of the leaves. The form of V. menzienii with very small 

 corollas somewhat resembles our plant in general appearance, but its lower leaves, 

 at least, are clearly pinnatifid, its peduncles exceed the leaves, and in the specimens 

 that 1 have seen the styles are well defined and the scales of the corolla present. The 

 type of leaf in N. spiclulata is the same as that of N. maculala. Our plant was found 

 high up in the Sierra Nevada, while N. parviflora is known only from much lower 

 altitudes. In addition to the type number some depauperate specimens, only 1 or 2 

 cm. high, were collected near the White Chief Mine, above Mineral King (No. 1522). 



Macrocalyx bipinnatifidus (Torr.) Bot. Ives Exped. 21 (I860), as Fhacelia micran- 

 tlta bipitinatifida. Type locality, "Yauipai Valley." 

 Johnson Canon, Panamint Mountains (No. 521). This is the Ellisia torrvyi of Gray. 



Macrocalyx membranaceus (Benth.) Trans. Linn. Soc. xvii. 274 (1837), under 

 Ellisia; Knntze, Rev. Gen. IT. ii. 434 (1891). Type locality Califoruiau, but not 



specifically given. 

 Near Mesquite Spring, Funeral Mountains (No. 332). 



Macrocalyx micrauthus (Torr.) Bot. Mex. Bound. 144 (1859), under Fhacelia. Type 

 localities, "stony hills near El Paso," Texas, and" Santa Cruz, near Tubac, Sonora." 



It appears to have escaped the notice of critical botanical students that Torrey's 

 Fhacelia micrantha has the broad, transversely lamellar placenta; of Macrocalyx(Ellisid). 

 The characters of the corolla, placenta?, and seeds, together with the general appear- 

 ance of the plant, show that it is closely related to M. ckrySanihemif 'alius. In the genus 

 Fhacelia the placenta) are of the ordinary type, and either parietal or sufficiently in- 

 truded to divide the ovary iuto two cells. In Macrocalyx the placenta) are parietal, 

 but not of the ordinary type. From near the line of insertion they expand abruptly, 

 into broad, transverse plates which lie against the walls of the ovary and form au. 

 interior lining to it. Most of the ovules are inserted on the inner faces of the pla- 

 centae, but one is sometimes found on the back. This latter phenomenon occurs nor- 

 mally in M. chrysanf hemij 'alius and frequently in M. micrauthus. The seeds of the latter, 

 on whichever side of the placenta, they are found, are transversely corrugated like 

 those on the inner face of the placenta in M. chrysanthemifolins. The very broadly 

 V-shaped rudimentary fold opposite each lobe in the corolla-throat of M. micrauthus 

 (a character quite anomalous in Fhacelia) is wanting also in the other species of 

 Macrocalyx, while the latter do have two scales inserted at a similar angle, opposite 

 each corolla lobe and near the base of the tube. 



Specimens were collected in the Vegas Wash (No. 418), in Furnace Creek Canon 

 (No. 448), in Jciinsoi) Canon (Nos. 560, 622), and in Surprise Canon (Nos. 657,712). 

 'I lie plant is a delicate annual and appears to be a common inhabitant of tem- 

 porarily moist and shaded spots in the canons of the desert mountains.
