EcniNOSPERMUM DEFLEXUMj Lelim . A-^p . No "d^ : Var. lohis calycinis oblongo-linearibus. Hills 

 near the Copper Mines, New Mexico, August, fl. & Cr.; Bigdoio. This differs from ray Euro- 

 pean specimens of this species in the narrower lobes of the calyx; but they are nearly as broad 

 as those of E. secundum, Kar, d Kir.^ which Alpli. DO. refers to E, deflexum. In specimens 

 of the latter from Altai^ (collected as I think by BungC;) the nutlets are somewhat heteronior- 

 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. Low^er 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.

 Grande, from El Paso to Eagle Pass, and west to the Gila. Usually about a foot high, and 

 much resembling E. Lappula.

TJ. S, Exph Exped. t. 13, ined. Hills and 

 ^o. 1570.) This species was first detected in 



Oregon by Dr. Pickering while connected with the United States 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.

HYDROPHYLLACEiE. 



Nemophila pedunculata, Benth, in Linn, Trans. 17, 2?. 275? Napa valley, California ; Thiir- 

 her. 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 5dobed in N. parviflora. 

 Alph. De Candolle (in Prodr.,) remarks that he found the placenttB 2-ovulate in both species, 

 and Fischer &: Meyer (1. c.) think they are not distinct. They may have examined a difierent 

 plant from the one here noticed, probably a mere variety of N. parviflora.
