360 Mr. J, Miers on the genus Thinogeton. 



i to 1 inch long ; the calyx is 5 lines long, 2 lines diameter ; the 

 corolla is 1^ inch long, contracted for the length of 5 lines to a 

 diameter of 1 line, and thence gradually swelling into a funnel 

 shape, is 1 inch across the mouth ; three nearly parallel nervures 

 extend along the middle of the lobes to the base of the tube ; the 

 stamens arise in the contraction of the tube, and the anthers, 

 which are double the length of those of the former species, are 

 connivent around the style in the middle of the corolla; the 

 flower on withering coils up in a spiral form, and the peduncle, 

 subsequently deflexed, increases to a length of 1| to ] J inch, 

 becomes thicker, and enlarges considerably at its apex ; the calyx 

 swells to an oblong oval form, nearly an inch long, 7 lines broad, 

 10-angular, with ten prominent costate ribs, vesiciform, with the 

 mouth* closed by five short connivent teeth : it encloses a berry 

 7 lines long, 5 lines diameter ; the pericarp is almost a putamen, 

 the upper moiety being thick and coriaceous, the lower half 

 thinner and more fragile; the dissepiment, and especially the 

 lunated placentae, become thickened, coriaceous and almost lig- 

 neous; it is apparently void of pulp, enclosing several seeds scarcely 

 a line in diameter and much compressed, which are described 

 by Dr. Hooker as being large ; but that term is evidently used in 

 comparison with those of Nicotianum, with which this genus was 

 thought to hold a close relation ; they are on the contrary smaller 

 than in many other genera of this tribe*. 



3. Thinogeton Lobbianum (n. sp.) ; — viscoso-pubescens, caule stri- 

 ato, flexuoso ; foliis ovalibus, irregulariter sinuato-angulosis 

 et dentatis, imo cordato-auriculatis, et in petiolum longius- 

 culum breviter attenuatis, 3-5-nerviis, tenuioribus, utrinque 

 tomento brevi glanduloso subincano pubescentibus, petiolo 

 tenui valde tomentoso ; floribus geminatis, calyce pubescente, 

 corolla sub-violacea, extus puberula, staminibus insequalibus, 

 corolla 2-3-plove brevioribus. — Columbia et Peruvia ; v. s. in 

 herb. Hook. (Columbia, Lobb. no. 299. Peru, Maclean.) 



This species is evidently intermediate between the two fore- 

 going : the stem is much smaller, more striated, far more flexu- 

 ose, with much shorter internodes, and altogether more pubescent 

 than the last described; the leaves are 2 inches long, If inch 

 broad, on a petiole of 2|- inches, but probably the lower leaves are 

 somewhat larger : the peduncles are 9 lines long, slender and erect, 

 but become suddenly deflexed on the withering of the corolla ; 

 the calyx is 4 lines long, 1-*- line diameter; the corolla 1£ inch 

 long, J inch broad in the mouth ; the fructiferous calyx becomes 

 almost globular, 5 lines long and 4 lines in diameter, contracted
