VI. PLANTJE WRIGHTIAN^. 17 



hypericacej:. 



Hypericum formosum, H. B. K. Nov. Gen. %■ Spec. 5. p. 196. t. 160; DC. 

 Prodr. I. p. 547. Valleys near Santa Cruz, Sonora, in springy places ; Sept. (860.) 

 — This accords very closely with the description and figure of Kunth's species. It 

 is the same as the H. Scouleri, Grai/, PL Fendl. p. 11, £rom New Mexico. The 

 Oregon plant has blunter sepals with scarcely any glands along their margins ; but 

 I suspect it is not specifically distinct. 



ELATINACE^. 



Elatine Americana, Am. ; Gray, Gen. lU. 1. p. 220. t. 95. Margin of moun- 

 tain streams near the copper mines, New Mexico ; Oct. 



CARYOPHYLLACE^. 



Silene Greggii (sp. nov. Siphonomori^ha) : viscoso-pubescens ; caulibus e radice 

 perenni assurgentibus ramosis foliosis ; foliis basi angusta sessilibus obovatis sub- 

 acutis ; pedunculis semper erectis calyce longe tubuloso clavato longioribus ; petalis 

 puniceis, lamina i-fida, lobis lineari-lanceolatis, coronae bipartitse segmentis truncatis 

 apice 3 - -t-dentatis ; capsula cylindracea breviter stipitata, — Stony hills at the 

 copper mines, New Mexico ; Aug. (861.) (Mountains near Saltillo, Gregg, No. 

 223.) — Stems 1 to 2 feet long, usually glandular and viscid. Leaves 1 to 2 inches 

 long, broadly obovate ; the bracts oblong-lanceolate. Panicle several-flowered. 

 Peduncles about an inch and a half, the calyx nearly an inch, in length. Lamina 

 of the petals 8 lines long ; the lobes entire, the middle ones somewhat larger than 

 the lateral, but the sinuses of equal depth. Capsule an inch long, nearly included 

 in the calyx. — Except in the form of the leaves, this plant differs little from what 



1 take for Silene laciniata, Cav. (No. 723 of Coulter's Mexican collection ; also 

 gathered by Wislizenus, at Cosiquiriachi), to which Lychnis pulchra, Cham. 8f 

 Schlecht. Linncea, 5. p. 234, may apparently be referred. 



S. Wrightii (sp. nov. Siphonomorpha) : undique viscoso-pubescens, multiceps e 

 caudice lignescente crasso ; caulibus adscendentibus spithama^is foliosis ; foliis ob- 

 longo-lanceolatis acuminatis sessilibus, inferioribus basi attenuatis ; pedunculis sub- 

 solitariis erectis foliis brevioribus calyce fructifero clavato ssepius longioribus ; den- 

 tibus calycis subulatis tubo vix dimidio brevioribus ; petalis albis, lamina 4-fida, 

 lobis lateralibus minoribus, centralibus 2 - 3-lobatis incisisve seu integris ; coronae 

 segmentis ovatis integerrimis ; capsula oblonga stipite paullo longiore. — In crevices 

 of rocks, mountain-sides near the copper mines, New Mexico ; Aug. to Oct. (862.) — 

 This is a low, very glutinous-pubescent species, forming tufts from a thickened root; 

 the weak and at length diff"use crowded stems from a span to a foot long. Leaves 



2 inches long, thin ; the lowest tapering into a margined petiole. Calyx 7 to 9 

 lines long. Lamina of the petals 3 lines long, sometimes nearly 4-cleft, often with 

 the middle lobes incised. 



Stellaria prostrata, Baldw. in Ell. Sk. 1. ^. 518. Along the Limpio, near its 

 head; June. (863.)
