LABIALS. 17 



the stem and veins of the leaves are generally tinged with purple ; the 

 whole plant is more glabrous; the pedicels, base of the calyx, and 

 corolla usually perfectly so, though there are sometimes a few hairs 

 about the top of the pedicel, and occasionally a few on the expandm<T 

 corolla. 



Mr. Baker states that Mr. T. B. Flower has sent from Gloucester- 

 shire a plant bearing the same relation to the ordinai-y form that the 

 var. paludosa does to the normal M. sativa. 



Mr. Baker refers to M. rubra, a plant collected by Dr. Windsor, at 

 Partington, Cheshire. This has the veins of the leaves, bracteoles, 

 and calyx teeth densely clothed with white woolly hairs. I have not 

 seen the corolla of this plant, so I do not kno\v if it does not also 

 partake of the increased hairiness. It appears to me to be M. gentilis, 

 var y.

Leaves spreading, subsessile or the lower ones shortly stalked, ellip- 

 tical or lanceolate-elliptical, attenuated at each end, acute, remotely 

 serrate, with few and distant lateral veins, subglabrous or tliinly hairy 

 above, glabrous beneath, except on the veins. Flowers in whorls 

 which are all separate, beginning above the middle of the stem. Bracts 

 similar to the leaves, but smaller and more lanceolate, the uppermost 

 ones sometimes without flowers; bracteoles strapshaped, acuminate, 

 ciliated, as long as or longer than the flowers. Pedicels glabrous. 

 Calyx glabrous at the base, cylindrical-campanulate ; teeth triangular, 

 scarcely half as long as the tube, sparingly hairy and ciliated. Corolla 

 half as long agam as the calyx, glabrous without and within.
