before them, as was first stated by Fenzl, who called them para- 

 stemones, but apparently did not notice their connexion with the 

 base of those stamens which stand before them. If these petaloid 

 bodies represent, as they probably do, the primary series of stamens, 

 the genus is not Portulacaceous, according to Fenzl' s own distinguish- 

 ing characters. — Some years ago, Sir Wm. Hooker (in Icones Plan- 

 tarum, 1. c.) figured a second species of the genus, of widely different 

 habit from the original 8. ligustrina, and likewise indicated a third 

 species, 8. Menziesii. But the plant he took for 8. ligustrina is. more- 

 over, a fourth species, which, like 8. Menziesii, has strongly three- 

 nerved leaves, in this respect differing from the rest of the genus. 

 The collection of the Exploring Expedition comprises the true S. 

 Ugustrina, and a new, narrow-leaved species allied to it; also 8. Nut- 

 tallii, and a well-marked new species of that group, with effuse 

 panicles and acute sepals.*

8. glaberrima ; panicula thyrsoidea contracta e cymulis br embus ; foliis 

 oblanceolatis lanceolatisve bad attenuatis sessilibus acutatis uninerviis; 

 sepalis obtusis ; seminibus muricatis. 



* The species now known of this curious genus may be disposed as follows : — 



* Panicula thyrsoidea, contracta, interrupta, nuda: folia iminervia.

2. Schiedea spergulina, Sp. Nov. Vide infra, p. 135. 



* * Panicula contracta, ramosa, deliquescens : folia trinervia.

4. Schiedea Hookeri : glabra ; panicula elongata laxiflora bad foliosa ; pedicelliz

 nerviis nunc quinquenerviis basi supra insertionem cormatam abrupte contract is ; sepalis 

 obtusiusculis. — S. ligustrina, Hook. 1. c. adnot, non Cham. & Schlecht. (Sandwich 

 Islands, probably Hawaii, Menzies.)
