280 labiat.k. [Teue/ium. 



not so coarse and less wrinkled than in T. quadr if avium, deeply crenate, 1 to 

 2 in. long*. Flowers (pale yellow ?) pedicellate, in pairs, in loose branching 

 terminal one-sided racemes. Bract-like floral leaves shorter than the calyx. 

 Calyx more or less inflated after flowering ; the npper tooth much broader 

 than the others. 



In waste places, Hance. Also on the adjacent continent and eastern India, from Sikkim 

 and Khasia to the Archipelago. 



3. T. quadrifarium, Ham.; Benth. in DC. Prod. xii. 583. Rhizome 

 creeping, but perhaps less so than in the last species. Stems erect, 1 to 1£ ft. 

 high in the Chinese specimens, often double that in India, densely hirsute 

 with spreading hairs, often assuming a golden hue. Leaves on short stalks 

 or nearly sessile, ovate or oblong, 1 to 2 in. long, serrulate, wrinkled and vil- 

 lous. Flowers (purple or whitish ?) pedicellate, in pairs, in loose branching 

 terminal one-sided racemes. Bract-like floral leaves ovate, often longer than 

 the calyx, but sometimes much smaller. Upper tooth of the calyx much 

 broader than the others ; the tube scarcely inflated after flowering. — T. For- 

 tunei, Benth. in DC. Prod. xii. 583. T.fulvum, Hance in Walp. Ann. iii. 270. 



Common in ravines, Champion and others. Frequent in the mountains of northern India. 



Order LXXXIV. PLANTAGINE^. 



Flowers regular. Sepals 4. Corolla small, scarious, with an ovate or cy- 

 lindrical tube and 4 spreading lobes. Stamens 4, inserted in the tube and 

 alternating with the lobes of the corolla, usually very long. Ovary 1-, 2-, or 

 4-celled, with 1 or more ovules in each cell. Style terminal, simple. Cap- 

 sule opening transversely or indehiscent. Seeds peltate, albuminous. Em- 

 bryo parallel to the hilum. — Herbs, with radical, tufted, or spreading leaves, 

 rarely branched and leafy. Flower-stalks leafless, bearing a simple spike or a 

 single terminal flower. 



A small Order, widely spead over the globe, but most abundant in the temperate regions 

 of the Old World. 4 



1. PLANT AGO, Linn. 



Flowers hermaphrodite, in heads or spikes on a leafless peduncle. Capsule 

 2- or 4-celled, with 2 or more seeds ; the other characters and geographical 

 range those of the Order, of which this genus contains all the species but two. 



1. P. major, Linn.; Dene, in DC. Prod, yjii.part i. 694. A perennial, 

 with a short thick root-stock. Leaves all radical, erect or spreading, broadly 

 ovate, often 4 or 5 in. long, entire or toothed, glabrous or pubescent, marked 

 with 7 (rarely 9 or 5) prominent ribs converging into a rather long petiole. 

 Peduncles usually longer than the leaves, bearing a long slender spike of small 

 sessile flowers. Sepals about 1 line long, green, with a scarious edge. Cap- 

 sule 2-celled, with 4 to 8 seeds in each cell. 



In waste places, Champion and others. A common weed in Europe and temperate Asia, 

 and spread with cultivation over almost every part of the globe.
