j8. hjssopifoliicm. L. 3-nerved ouly at base. 

 lY quite smooth. G. Als. 



ii, L. more ilmn 4 in a set on the main stem, 

 1-nerved {ift G. palustre i/te stem is some- 

 times smooth) . 



a. Fncit not granular {sometimes lacunoso- 

 rugose) . Stem firm at the hose, ^-edged 

 or with 4 prominent ribs. 



4. msTubricuHa. L. ol)ovate, dull, in sixes 

 on stem, in fours on brandies. Stems hairless, 

 decumbent. Branches few-flowered, CDding in 

 a simply trifid umbel. (Divisions of Cor. with 

 a filiform cusp, Gaud.) Pedicels of Fr. spread- 

 ing. Stems slender. L. very thin. Bracts 

 mostly solitarg. Fl. not more than half as 

 large as those of G. Mollugo. p. Stony. 

 Canton of Tessin, Koch. Bert, joins this to 

 G. Mollugo. 



5. mediterraneum. " Stem ascending, 

 smooth. Lower L. in fours, obovate, mucronu- 

 late ; others in sixes, lineari-lanceolate, some- 

 what rough on margin. Stalks 2-3-cleft. Di- 

 visions of Cor. awned. p.? Restonica in Cors. 



and in Lig."— DC. 



Not in Bert. 



6. Soleirollii. " Softly pubescent. Hau's 

 spreading. Lower L. in fours ; upper in fives, 

 ovato-oblong, acute. Cor. hairless : divisions 

 wdth a short awn. Seeds somewhat ovate, p. 



6. Cape Revelata in Cors. Tioo or three 

 inches long" — Bert. 



7. aristatmn. " Stem-L. in eights, lan- 

 ceolate, mucronate. Stem erect. Pan. large. 

 Pedicels always nearly erect. (Divisions of 

 Cor. with a short setaceous mucro, Gaud.) p. 



7, 8. Rough hills, s. G. Tyrol."— Koch. 

 Does not appear to he the plant of Linn. 



In this and the five foUowdng species the 

 characters are far from satisfactory. I am 

 fully persuaded that they do not aU form a 

 single species, but am not equally confident 

 that I have divided them rightly. In all which 

 I have had the opportunity of examining, the 

 cusps of the corolla in their perfect state are 

 slender and setaceous. 



8. erectum. Stem weak, smooth. L. in 

 sixes or eights, lineari-lanceolate (lanceolate, 

 Sm.). Midrib slender, often inflated at base. 

 (Pricldes of the margin hooked, Sm.) Cor. 

 hairless. Pr. smooth, p. 6, 7. Dry hills. 



Under the name of G. erectmn or G. luci- 

 dum this is said to be known throughout Eu- 

 rope ; but no one except Sir J. E. Smith men- 

 tions any hooks to the marginal prickles, and 

 these I never could find. Koch says that 

 the fruit is wTinkled ; Smith, that it is smooth 



and even. It is known from Mollugo by its 

 more upright stem, more slender habit, smaller 

 and less diffuse panicle, and somewhat glossy 

 and narrower lower L. ; but in all these parti- 

 culars there are intermediate states. Smith 

 assigns to this an acuminate cusp, while he 

 gives to G. Molhigo " a tumid point, not a 

 bristle." 



9. Mollugo. Young stems downy. L. 

 about 8 in a whorl, obovato-oblong, dull. Mid- 

 rib slender. Branches of Pan. spreading, many- 

 flowered. Pr.-stallis divaricate. Pr. wrinkled. 

 p. 7, 8. Hedges, thickets, and dry banks. 



10. lucidum. "L. about 8, linear, mu- 

 cronate, rigid, shining, with a strong midrib. 

 Lower branches of Pan. spreading horizontally. 

 Pruit-stallcs divaricate. Pr. somewhat rugose. 

 p. 5-7. Barren stony, s. Alps."- — KocH. 



Both DC. and Bert, refer the G. lucidum of 

 AUioni (also quoted by Koch) to a variety of 

 G. erectum. As I do not feel confident that 

 the foreign G. lucidum is the same as our G. 

 erectum, I have insei'ted both. G. lucidum 

 should have a strong midrib, which G. erectum, 

 1 believe, never has. 



11. cinereum. " Stem woody at base, 

 much branched, smooth. L. 6-8, eUiptico- 

 linear, glaucous beneath, rigid, mucronate, often 

 reflexed, hardly rough on the margin. Divi- 

 sions of Cor. with a setaceous mucro. Pi', quite 

 smooth, p. Open. s. Pr. It. VaU."— DC. 

 Referred by Koch to G. lucidum ; by Bert, to 

 G. erectum. The almost ■ivoocly base of stem, 

 which is entirely smooth, the strongly revolute 

 margins of the L., and their thick, firm, and 

 even midrib, persuade me that this is quite 

 different from anything I have seen in England. 



12. littorale. Stem rigid. Branches crowd- 

 ed. L. about 8. Branches of Pan. trichoto- 

 mous, erect, pubescent. Cor. hairy : divisions 

 with a short awn. Seed somew"hat ovoid. 

 Smell of Fl. very strong and disagreeable, p. 

 5, 6. Thickets on sandy shores. Sic. 



13. veruBa. Stem round in lower part, with 

 4 ribs, hairy. L. 8-12, linear. Margin re- 

 volute, rough above, downy beneath. Branches 

 of Pan. neai'ly horizontal when in fi-uit. Cor. 

 yellow : divisions mth a very short cusp. p. 

 7, 8. Dry banks. 



/3. vero-mollugo. PI. yellowish-white. Ger. 



14. arenarium. Prostrate, much branched, 

 hairless. L. 6-10, lineari-oblong. Pan. some- 

 what cylindrical, verticUlate : the PI. -stalks 

 veiy short. Fl. yellow. Pr. large and some- 

 what fleshy, p. 5, 6. Sandy shores, w. Fr.
