much less deeply crenate than usual ; with narrower petals and a more lunate tu- 
bercle on the filaments. The two forms seem to run into one another. as 
19, M. nana (E. & Z.! No. 395) ; minute, suffruticose, thinly covered 
with very short, white, stellate hairs ; leaves on long petioles, elliptical 
or sub-rotund, inciso-crenate ; stipules ovate, amplexicaul ; peduncles 
much longer than the leaves, the bracts oblong-acute; calyx campanu-

Root woody. Stems slender, 2-4 inches long, slightly branched. Leaves scarcely 
inch long ; petioles nearly as long. Allied to M. erodioides, but with shorter, 
roader, rounder, less cut leaves, and different pubescence. 
Group 4, DEenTat#, (Sp. 20-28). 
20. M. gracilis (Harv.); stems trailing, very slender, sub-sim- 
ple, nearly glabrous ; leaves remote, sub-rotund, 5—7-crenato-lobulate, 
sparsely stellate on both sides ; stipules amplexicaul, ovate-acuminate, 
shorter than the petioles ; peduncles much longer than the leaves ; 
bracts connate at base, subulate ; calyx glabrous, deeply 5-fid, the lobes 
broadly subulate, acute, 2 as long as petals ; anthers taper-pointed, 
much longer than the filaments ; ovary pubescent.

Of this well-marked and pretty little plant I have as yet only seen a single speci- 
men, which I should probably have referred to M. Linneoides, Burch. had not a 
very different plant, equally answering to De Candolle’s diagnosis, been so named 
by Eck. & Zey. The present is one of the slenderest of the genus, with leaves like 
those of Veronica hederefolia, but smaller, } inch in diameter. Peduncles more 
than an inch long, flowers 2 lines long. 
21. M. Linneoides (Burch. Cat. No. 1878 ; fide E. & Z.) ; shrubby, 
procumbent, glabrescent or stellato-pubescent; leaves on short pe- 
tioles, stellato-pubescent on one or both sides, broadly elliptical or 
roundish, very obtuse, crenato-dentate stipules ; ovate-acwminate, equal- 
ling the petioles ; peduncles glandularly pubescent and viscid, much 
longer than the leaves ; bracts ovate-acuminate, connate beyond the 
middle ; calyx campanulate, semi-5-fid, densely glandular, with deltoid, 
acute segments more than half as long as the petals ; ovary turbinate, 
densely pubescent. DC. Prod. 1. p. 497. —
