1. P. arguta, Benth. in DG. Prod. xii. 164. An erect, more or less 

 hairy, rather coarse branching annual, 1 to \\ ft. high. Leaves on rather long 

 petioles, broadly ovate, deeply toothed, usually about 2 in. long, stained with 

 purple underneath, or sometimes on both sides. Racemes 1 -sided, 3 to 5 

 in. long. Mowers small. Calyx-tube hispid. — Mentha reticulosa, Hance in 

 Walp. Ann. iii. 247. 



Cultivated for its seed, but also found wild in the island, Hance. Also on the Chinese 

 continent and in Japan. The leaves are nearly those of P. odmcddes, var. crispa, or Denti- 

 dia nmildnensis. Lour. ; but the spikes are more slender, the calyx less hairy, and longer 

 when in fruit. We are not however sufficiently acquainted with the native form of the plant 

 to judge how far it may he really specifically distinct from the common Indian P. ocimoides. 



2. P. lanceolata, Bentk. in DC. Prod. xii. 164. An erect much- 

 branched annual, seldom 1 ft. high, glabrous or more or less hoary with a' 

 minute pubescence, but without stiif hairs. Leaves ovate or the upper ones 

 lanceolate, | to f or rarely 1 in. long, slightly toothed, on petioles of 3 or 4 

 Hues. Racemes slender, 1-sided. Flowers smaller than in P. arguta. Calyx 

 sKghtly hoary but not hairy. Anthers of the upper stamens smaller than the 

 lower ones, but with 3 perfect cells. — Hedeoma nepalends, Seem. Bot. Her. 

 404 ; not Benth. 



In waste places, Hance ; also Wright, On the adjoining continent to Amoy. The trae 

 Hedeoma nepalensis is very like this plant, but is more or less hispid, and has Slways the 2 

 upper stamens rudimentary or sterile, a distinction which in this family has always been regarded 

 as generic, although in this instance the H. nepalensis might be more naturally removed to 

 Ferilla. 



5. MENTHA, Linn. 



Calyx nearly regular, B -toothed. Corolla with a short tube and a campa- 

 ntdate 4-lobed limb, nearly regular, or the upper lobe rather broader, and 

 sometimes slightly notched. Stamens 4, equal and erect ; the anthers 2-celled. 

 Nuts smooth. — Perennial herbs. Flowers rather small, in dense false-whorls, 

 which are either collected in terminal heads or spikes, or axillary and distant. 



A genus not numerous in species, widely diffused over the greater part of the globe, with- 

 out the tropics, one speciesi extending also into the tropical regions of the Old World. 



1. M. arvensis, Linn.; Benth. in DC. Prod. xii. 171, var. javanica. 

 Stem decumbent or ascending, more or less hoary with closely reflexed hairs. 

 Leaves lanceolate or ovate-lanceolate, 1 to 1^ in. long, narrowed into a short 

 petiole, the upper ones smaller; false-whorls globular, many-flowered, all 

 axillary and distant; the uppermost pair of leaves often without flowers. 

 Calyx usually about 1 line long. — M. javanica, Blume ; Benth. in DC. Prod, 

 xii. 173. 



In ditches, Saywan, Hance. Very strongly aromatic. The same variety occurs in Ceylon, 

 the Indian Archipelago, the Philippines, and northward to Chuaan. The species itself ranges 

 all over Europe and temperate Asia, where the leaves are generally (but not always) broader 

 and not narrowed at the base, but the North American forms (M. canadensis, Linn.,) connect 

 the Javanese with the European too closely to be any longer regarded as specifically distinct. 



6. SALVIA, Linn. 

 Calyx 2-lipped, the upper lip entii-e or with 3 minute teeth, the lower one 

 2-oleft. Corolla with the upper lip erect, concave or ai-clied ; the lower spreadr 

 ing, 3-lobed, the middl lobe often notched or divided. Stamens 2, buteasilv
