This is a prostrate plant, with much the habit of a Nolana, its 

 branches measuring a foot and upwards. Its petioles and pedi- 

 cels are erect, and therefore are all somewhat secund : I have not 

 seen any cauline leaves, but the floral leaves are much smaller, 

 greatly narrower, and upon a shorter petiole than in the follow- 

 ing species ; the pedicels are 2 to 4 lines long, the calyx is 3 lines 

 long, and 1 line diameter, swelling afterwards to a length of 7 

 lines and a diameter of 5 lines : the corolla is 15 or 16 lines long, 

 and 10 to 13 lines broad across the border ; it is pubescent out- 

 side, is persistent, and on withering, coils up in a spiral form, 

 when the peduncle increases to a length of 9 lines and becomes 

 suddenly reflexed. The berry is 4 lines in diameter, enclosed 

 within the enlarged vesiciform calyx. 



2. Thinogeton Miersii. Dictyocalyx Miersii, Hook. fil. Linn. 

 Trans, xx. p. 203 ; — subpubescens, foliis ovatis, acutis, basi 

 insequalibus, cordato auriculatis, et in petiolum angustatis, ir- 

 regulariter sinuato-angulatis, angulis subobtusis, 3-5-nerviis, 

 crasso-coriaceis, utrinque pilis brevibus rigidiusculis articulatis 

 conspersis, longissime petiolatis ; floribus solitariis vel geminis, 

 lateralibus, corolla sub-violacea extus puberula, limbo vix expla- 

 nato, staminibus corolla brevioribus. — Ins. Gallapagos, z?. s. in 

 herb. Hook. (Charles et Albemarle Islands, Darwin.) 



This plant possesses a habit similar to that of the former spe- 

 cies. The branching stems of woody texture are fistulose, smooth 

 and terete. The leaves are from 2| to 3 inches long, 2 to 2| 

 inches broad, on a channeled petiole 5 inches long, that is nearly 

 rectangular with the stem : they arc almost smooth, or sparsely 

 covered with very Short rigid hairs : the peduncles ai-e slender,
