332 SELAGINACE^. Gymnandra. 



Order CII. SELAGINACE^. 



Shrubs or herbs, of various habit, confined to the southern hemisphere, except 

 two anomalous northern genera of dubious association, in character most like 

 Verbenacece, but the solitary ovules anatropous and suspended, and the radicle 

 of the terete straight embryo superior. 



1 . G-YMN ANDRA, Pall, (rvfxrog, naked, driiQ, man ; stamens somewhat 

 protruding.) — Calyx spathaceous, cleft anteriorly, entire or 2-3-toothed pos- 

 teriorly. Corolla tubular, ampliate at the throat; limb 2-labiate ; upper lip 

 entire, erose- 2-3-crenulate, or 2-cleft ; lower usually longer, 2-3-cleft. Stamens 2, 

 inserted in the throat of the corolla, not surpassing its lobes : anthers versatile, 

 confluently 1-celled. Ovary 2-celled, 2-ovulate: style filiform and elongated: 

 stigma subcapitate or 2-lobed. Fruit dry or slightly drupaceous, small, included 

 in the calyx and marcescent corolla, separating into two akene-like nutlets, or one 

 of them often abortive. Seed suspended : embryo a little shorter than the fleshy 

 albumen. — Perennial and subcaulesceut glabrous herbs ; with the aspect of Syn- 

 thjris in Scrophulariacece (p. 285) ; rootstock^ somewhat creeping: leaves alter- 

 nate ; the radical obovate or oblong and petioled ; those of the scapiform and 

 simple flowering stem sessile: flowers in a. dense terminal spike, each solitary 

 and sessile in the axil of a bract : corolla bluish. A few montane and arctic 

 Asiatic species, two of them reachhig N. America. — Pall. It. iii. 710 ; Choisy in 

 DC. Prodr. xii. 24; Benth. & Hook. Gen. ii. 1130. 



G. Gmelini, Cham. & Schl. Somewliat robust, a span to a foot high : radical leaves 

 ovate or oblong, mostly obtuse at both ends, rcpand-crenate (2 to' 4 inches long) : cauline 

 smaller, passing into bracts of the dense and thick oblong spike : stamens much shorter 

 than the upper lip of the corolla, exceeding the style. — Linn. ii. 561; Hook. Fl. ii. 102. 

 6'. lioreulis, var., Pall. 1. c. G. ovata & reniformis, Willd. Lagotts ylauca, Gaertn. in Nov. Conun. 

 Tetrop. xiv. 533, t. 18, fig. 2. (Bartsia gijimandm, Pursh, Fl. ii. 4-30, referred here as to 

 plant of Columbia River, is probably Sijnthyris ?•«;»•«. ) —Unalaska, PopofE Islands, &c., 

 recently coll. by Harringlon and EllioU. (Kamts., &c.) 



G. Stelleri, Cham. & Schl. 1- c. Slender and smaller : radical leaves oblong, acute, 

 more attenuate at base, unequally and obtusely serrate: stamens about equalling the 

 upper lip of the corolla, shorter than the style. — Hook. 1. c. G. minor, dentala, & (jraahs, 

 Willd. — Kotzebue Sound, Lnij & Collie. Arctic coast, Richardson. Perhaps Island of St. 

 Lawrence, Chamisso. St. Paul's Island, EllioU. (Arctic Asia.) 



Order CIII. VERBENACE.E. 



Herbs or shrubs (in tropical regions some are trees), with chiefly opposite or 

 verticillate leaves, no stipules, bilabiate or almost regular corolla, with lobes 

 imbricated in the bud, mostly didynamous stamens, single style with one or two 

 stio-mas, an undivided mostly 2-carpellary but more or less completely 2-4-celled 

 (rarely 8-locellate) ovary, a pair of ovules to each carpel (one to each locellus or 

 half-carpel) ; the fruit either drnpaceo>us and 2-4-pyranous, or dry and separating 

 at maturity into as many nutlets ; embryo straight, and in true Verbenacea with 

 the radicle inferior. P/iryma, appended to this order for lack of other afifinity, 

 is a notable exception. Albumen in our genera scanty or none. Inflorescence 

 various. Foliage sometimes aromatic.
