CLXXIV. GLOBULAEIE^. 619 



Corolla monopetalous, hypogynous, 2-labiate, anisostemonous, cestivation imbricate. 

 Stamens 4, didynamous, inserted on the corolla. Ovakt l-celled; ovule solitary, 

 pendulous, anatropous. Fetjit a caryopsis. Embeto albuminous; eadiole superior. 

 — Flowees capitate. 



Sheubs or UNDEESHEUBS, or evergreen heebs. Leaves alternate, simple, entire, 

 aggregated at tlie base of tlie branches, tbe upper smallest, scattered, spathulate, 

 contracted into a petiole, exstipulate, marceseent. Flowbes S , irregular, capitate 

 on a convex paleaceous receptacle, surrounded by an involucre of many series 

 of bracts. Caltx herbaceous, monosepalous ; t^^be tetra.gonal after flowering ; 

 throat usually closed by hairs ; limb 6-fid, regular or rarely 2-lipped, the upper lip 

 3-fid, the lower 2-fid. Coeolla monopetalous, hypogynous ; tube cylindric ; Umb 

 1-2-labiate, upper lip entire or 2-lobed, or very short or obsolete, lower longer, 

 3-partite or -fid or -toothed, aestivation imbricate. Stamens 4, inserted at the top 

 of the corolla-tube, alternate with its lobes, the fifth wanting between the lobes of 

 the upper lip ; filaments filiform, exserted, the upper a little the shortest ; anthers 

 reniform, 2-celled in bud, cells then confluent, opening at the top by a single slit. 

 OvAET free, l-celled, seated on a hypogynous minute disk, which is rarely reduced to 

 an anterior gland, or absent ; style terminal, simple ; stigma undivided or shortly 

 2-lobed ; ovule solitary, pendulous, anatropous. Caetopsis enveloped by the calyx, 

 mucronate by the persistent style-base. Seed inverted. Embeto straight, in the 

 axis of a fleshy albumen ; cotyledons ovoid, obtuse ; radicle next the hilum, superior. 



GENUS. 

 GloTjuIaria. 



We have indicated tlie affinities between Glohulariea and Verbetiacets, Stilbinece, Myoporinea, and 

 Selaginem, affinities whicli are not disturbed by the l-celled and 1-ovuled ovary of Glohidariecs, since the 

 base of the style is geniculate and a little furrowed on the back, which has led A. de CandoUe to 

 suspect that the pistil is 2-carpellary, and that the posterior carpel is arrested. Some botanists have 

 noticed a close connection between Olohulariece and Dipsacem, the latter only diifering in the epigynous 

 corolla, and the opposite or whorled leaves, Glohdariece also present some analogy with JBninoniacets, 

 founded on the capitate inflorescence, hypogynous corolla, l-celled 1-ovuled ovary, and anatropous ovule ; 

 but in Brunoniaceis the corolla is regular and isostemonous, and the ssstivation is valvate, the stamens are 

 hypogynous, the anthers 2-celled, the ovule is erect, and the embryo exalbuminous. There are also 

 some points of resemblance between Glohularieee and CalycerecB ; the inflorescence is the same, the ovary 

 is l-celled and 1-ovuled in both, the ovule is pendulous and anatropous, and the embryo albuminous ; but 

 CalyeerecB dififer in their epigyny, the regularity, isostemony and valvate aestivation of the corolla, and 

 in the syngenesious stamens. GlohvlarieeB principally inhabit the south-west countries of Europe, and are 

 not met with farther north than 64°. 



Some species were formerly used medicinally; the leaves of Gldbidaria communis are reckoned 

 among detergent and vulnerary medicines. The G. Alypum replaces Senna in the south of Europe, and is 

 a very decided purge.
