787 



ovate, on long peduncles ; bracteas and calyxes spinose ; leaves 

 fascicled, linear-oblong, with revolute, quite entire margins, his- 

 pid, as well as the stem, which is branched. Ij . ? G. Native 

 of Rio Grande. 



Capitate-fiovcercd Gardoquia. Shrub. ? 



24 G. SPICA'TA (Spreng. 1. c.) spikes terminal, villous ; leaves 

 subfascicled, spatulate, almost quite entire, rough, Tj G. Na- 

 tive of Rio Grande. 



Spiked-flowered Gardoquia. Shrub. ? 



Cult. Most of the species of Gardoquia bear large scarlet 

 blossoms, and are, therefore, showy, and worth cultivating. A 

 light rich soil, or one composed of equal parts of sand, loam, 

 and peat, will suit the species well. Cuttings strike root rea- 

 dily in the same kind of soil, with a hand-glass placed over 

 them. 



LI. GLE'CHON (from -yXrixwv, glechon, the Greek name 

 for Pennyroyal ; this genus has been so called from its similarity 

 to Pennyroyal.) Spreng. syst. cur. post. p. 227. Benth. lab. 

 p. 405. 



LIN. SYST. Diandria, Monogynia. Calyx ovate or tubu- 

 lar, 13-nerved, equal or sub-bilabiate, 5-toothed, the 2 lower 

 teeth usually the longest. Tube of corolla equalling the calyx, 

 naked inside ; limb bilabiate; upper lip emarginate or semi-bifid, 

 falcate, arched or galeate, erect, or lying on the lower lip ; 

 lower lip spreading, with flat entire lobes : lateral lobes the 

 broadest, often adhering to the upper lip at the base. Two 

 lower stamens fertile, ascending under the upper lip, or exserted 

 a little from the notch ; filaments glabrous ; anthers 2-celled : 

 cells linear, parallel, diverging, or at length divaricate. Style 

 glabrous, having the upper lobe very short, and the lower one 

 elongated and flattened. Achenia oblong, smooth, dry. Usu- 

 ally canescent, suffruticose plants. Leaves for the most part 

 small ; floral leaves similar to the others, rarely smaller, and 

 bractea-formed. Whorls axillary, 2-6-flowered, rarely disposed 

 in short racemes towards the tops of the branches. Corollas 

 yellowish, flesh-coloured, or blue. The galeate upper lip of the 

 corolla in this genus separates it from all other genera of tribe 

 Melissinece.

 Native of Brazil, near Anjo, in the Missions of the Uruguay ; 

 and near Santa Maria, in the province of Rio Grande do Sul, 

 very plentiful. Shrub procumbent at the base ; branches 

 ascending, clothed with tomentose pubescence. Floral leaves 

 conforming to the rest, shorter than the flowers. Corolla

 nearly glabrous ; calycine teeth very short, nearly equal ; upper 

 lip of corolla large, galeate. ^ . F. Native of the South of 

 Brazil, Sello. Branches clothed with hoary pubescence. Leaves

3 G. SERPYLLIFOLIA (St. Hil. mss. ex Benth. lab. p. 407.) 

 leaves small, petiolate, ovate, obtuse, quite entire, greenish on 

 both surfaces, glabrous ; calycine teeth subulate, rather un- 

 equal : longer ones equalling the tube ; upper lip of corolla 

 large, falcate. I? . F. Native of Brazil, in the province of 

 Cisplatin, among stones from Santa Theresa to Rocha. Branches 



prostrate, glabrous, or finely tomentose. Leaves 2-3 lines long, 

 form of those of Thymus Serpyllum, glandularly dotted ; floral 

 leaves conforming to the others, but usually a little larger, ex- 

 ceeding the calyxes. Whorls 2-flowered. Corollas flesh- 

 coloured, size of those of G. thymoldes, but the upper lip is less 

 incumbent. Perhaps a variety of G. marifblla.
