'■'"hen I described H. thecatum I considered it to be distinct 

 from 1'. minutum, because the tube of the corolla v;as not exserted 

 from the calyx, in the manner represented in the figure of I^^. 

 minutum, and in the case of the latter, the formation of sheath- 

 clad stems is neither represented nor described; but my plants of 

 I-. thecatum have nov^ produced flwrers with a corolla-tube nearly 

 or ruite as long and as much exserted from the calyx as is repre- 

 sented in the Botanical tfegazine, and when the plant is more deep- 

 ly set in the soil the stem-formation is not evident. Other 

 chfracters being arT>8rently the same, I have now no doubt that 

 li. thecatum is identical .with M. minutum. The extent of the ex- 

 sertion of the corolla -tube rrobpbly derends upon the temnerature 

 and amount of moisture received during the formation of the 

 flo"^er, as I have found a variation of these conditions to pro- 

 duce similar results in other species. 



13. G. oviforme, N.E.Bp. (Fig. 123). Grov/ths^ subcylind- 

 ric-ovoid or nerrovrly obovoid, 4-6 lines long and 2-S-| lines 

 thick, very .convex at the top (tyne ■^. ) , grass-green, minutely 

 tuberculpte or papillate all over, soft and pulpy, often enclosed 

 in their old r-hitish or prle brownish skins. Calyx &-7-lobed, 

 included, or only the tips of the lobes exserted from the old 

 skin. Corolla about 7 lines in diameter; petals about 30, stated 

 to be DP'le mas'enta, but not seen in a fresh strte. -^tyle none; 

 stiffraas 6, about l|r line long, filiform. Capsule 2-3 lines in 

 'diameter, 6-V8lved, 6-celled, with small cell-wings, and broad ' 

 marginal valve-wings. — -•'. ov'forrae, N,S, Bp. in Journ. Linn. 3oc.

I think it quite probable that the floxvers of this species 

 are sometimes white. The minute papilla-like tubercles on this 

 plant readily distinguish it from all other species.
