AIZOACEAE. 



MOLLUGO, L. 



M. flavescens, Anderss. (1), 226, & (2), 96, t. 15, f. 2; Rob. & 

 Greeum. (1), 146 as to pi. Chatham and pi. Albemarle. ? M. verticillata, 

 Hook. f. (3), 232; Anderss. (1), 225, & (2), 96; not L. — Albe- 

 marle Isl. : Darwin, identity doubtful ; Macrae, identity doubtful ; 

 Baur, identity doubtful. Charles Isl. : Snodgrass & Heller, no. 441 

 (lib. Gr.). Chatham Isl.: Darwin, identity doubtful ; Andersson (hb. 

 Gr.) ; northern part, Baur, no. 155 (hb. Gr.) ; southwestern part, lower 

 region, Baur, no. 154 (hb. Gr.). Indefatigable Isl. : northern part, 

 Snodgrass & Heller, no. 667 (hb. Gr.). Endemic. 



In all these specimens so far as seen the pedicels are rather short, 

 some ascending, others deflexed. Distinguishable is 



Var. floriana. M. Jlavescens, Rob. & Greenm. 1. c. as to pi. Charles 

 Isl. Pedicellis 4-9 mm. longis, omnibus erectis vel adscendentibus ; 

 floribus paulo quam illi formoe typicoe majoribus. — Charles Isl. : 

 Cormorant Bay, Baur, no. 137. Endemic. In this variety as in the 

 typical form the seeds are black, dull, and minutely tessellated. 



M. gracillima, Anderss. (1), 226, & (2), 96; Rob. & Greenm. (1), 

 146. M. gracilis, Anderss. (2), t. 15, f. 3. — Galapagos Ids. : 

 Habel. Albemarle Isl. : Iguana Cove, S?wdgrass & Heller, uos. 79 

 (hb. Gr.), 122 (hb. Gr.) ; Tagus Cove, abundant everywhere up 

 to 300 m. alt., Snodgrass & Heller, no. 192 (hb. Gr.). Charles Isl. : 

 in the driest parts of the lower region, Andersson (hb. Gr.). James Isl. : 

 Orchilla Bay, Baur, no. 153 (hb. Gr.). Endemic. By Hook. f. & 

 Jacks. Ind. Kew. ii. 253, this species is reduced to M. verticillata, L. It 

 differs, however, in several ways, namely by having smaller flowers, a 

 shorter capsule relatively to the blunter sepals and in its minute black 

 tessellated, not ribbed seeds.
