142 UNITED STATES AND MEXICAN BOUNDARY. 
KRYNITZKIA LEIOCARPA, Fisch. & Mey. Ind. T, Sem. H. Petrop. 1841, p. 52. Grassy hills near 
San Luis Rey, February ; Parry. Also found in California by the Rev. A. Fitch. 
EcurosPERMUM DEFLEXUM, Lehm. Asp. No 93: Var. lobis calycinis oblongo-linearibus. Hills 
near the Copper Mines, New Mexico, August, fl. &fr.; Bigelow. This differs from my Euro- 
pean specimens of this species in the narrower lobes of the calyx; but they are nearly as broad 
as those of E. seeundum, Kar. & Kir., which Alph. DC. refers to E. deflexum. In specimens 
of the latter from Altai, (collected as I think by Bunge,) the nutlets are somewhat heteromor- 
phous, two opposite ones having rather a broad margin, which is pectinate with flat glochidiate 
prickles ; the other two are smaller, with a much narrower margin and shorter prickles. Our 
plant has a biennial root. The stem more than 2 feet high. Lower leaves 2 inches long and 
5-7 lines wide, villous with spreading hairs. Racemes numerous, forming a loose terminal 
panicle, bracteate to the summit. Pedicels closely deflexed. Corolla salver-form, 2 lines long, 
with a short tube and obtusely 5-lobed border ; the throat furnished with 5 very prominent tuber- 
cles, Nutlets homomorphous ; the aculei marginal only, in a single series, confluent at the base. 
ECHINOSPERMUM PATULUM, Lehm. Asp. No. 95. Gravelly and sandy soils. Valley of the Rio 
Grande, from El Paso to Eagle Pass, and west to а бїз. E about г a 3o high, and 
much resembling E. Lappula. 0% жә 
EcHINOSPERMUM STRICTUM, Nees. in Маадай. Trav. унэ A Torr. ф Gray in Bot. Pope Rep. p. 
15. E. Texanum, Scheele in Linnæa 25, p. 260. Cynoglossum pilosum, Nutt. Gen. 1, p. 114? 
Near San Antonio, Texas; Thurber. Western Texas; Wright, Хо. 1513. Nutlets with an 
inflexed border and a deeply depressed disk ; almost as in Omphalodes. Fiowers pale blue. 
ERITRICHIUM PTEROCARYUM, (n. sp.,) Torr. in Bot. U. S. Expl. Exped. t. 13, ined. Hills and 
rocky places near El Paso, ete.; Bigelow. (Wright, No, 1570.) This species was first detected in 
Oregon by Dr. Pickering while connected with the United Statès Exploring Expedition. It is 
about a foot high and remarkable for its conspicuously winged fruit, the wings being as broad 
as the body and more or less toothed above the middle. In the Oregon specimens, and in some 
of those from New Mexico, one of the nutlets is apterous. 
CYNoGLossuM GRANDE, Dougl.; Hook. Fi. Bor.-Amer. 2, p. 85. Napa valley, California, 
March ; Thurber. Also found by Mr. Fitch in the same State. 
HYDROPHYLLACE. 
NEMOPHILA PEDUNCULATA, Benth. in Linn. Trans. 17, p. 275? Napa valley, California; Thur- 
ber. This is the same as No. 480 of Coulter's Californian Collection. It is named N. parviflora 
by Dr. Harvey, (MSS.,) but differs from that species in the seeds being more numerous (10-13) 
and tuberculate, not 4, and impressed-punctate. The arillus is calyptriform in both species. 
The leaves, too, are usually 7-9-lobed in N. pedunculata, and only 5-lobed in N. parviflora. 
Alph. De Candolle (in Prodr.,) remarks that he found the placente 2-ovulate in both species, 
and Fischer & Meyer (1. c.) think they are not distinct. They may have examined a different 
plant from the one here noticed, probably a mere variety of N. parviflora. 
NxMoPHILA AURITA, Lindl, Bot. Reg. t. 1601, Alph. DC. Prodr. 9, p. 290. San Diego, Cali- 
fornia; Parry. San Pasqual, in the same State, Мау; Thurber. 
NEMOPHILA LINIFLORA, Fisch. & Mey. Sert. Petrop. t. 5. Dana’s Ranch, and grassy plains 
below Los Angelos, March; Parry. Napa Valley, May; Thurber.
