124 PHANEROGAMIA. 



3. Drfmaria viscidula, Sp. Nov. 



D. mule diffuso glabro; ramulis cum inflorescentia glanduloso-pubes- 

 centibus; foliis subreniformi-ovatis in petiolum contract is glabriusculis ; 

 stipulis setaceis; cyma corymbosa pluriflora ; pedicellis (fructiferis 

 erectis) alaribus flore duplo longioribus ; sepalis oblong is acutis glan- 

 dulosis petala submquantibus. 



Hab. Andes of Peru, with the preceding. 



Stems diffuse, a foot long, from an annual root, slender, glabrous, 

 except the very summit. Leaves 3 or 4 lines long, by 4 or 5 in width, 

 dilated round-ovate or somevrfiat reniform, glabrous or slightly pubes- 

 cent, abruptly contracted into short and margined, mostly hairy petioles, 

 or the lowest cauline with a petiole as long as the blade. Stipules of 



2 or 3 capillary interpetiolar setce on each side, often as long as the 

 petioles, tardily deciduous. Peduncles half an inch or an inch long, 

 erect, clothed with a short glandular and glutinous pubescence, bearing 

 a cyme of 5 to 15 rather crowded flowers. Bracts setaceous-subulate, 

 glandular. Pedicels glandular-pubescent and viscous ; the central ones 



3 or 4 lines long ; the lateral only one or 2 lines long ; all erect in 

 flower and fruit. Calyx a line and a half long; the sepals ovate-oblong, 

 or oblong-lanceolate, with conspicuously scarious-petaloid margins, 

 acute, or the narrowed point rather obtuse, three-nerved, glandular 

 externally. Petals scarcely longer than the calyx, white, narrowly 

 cuneate, two-cleft to the middle; the lobes spatulate. Stamens 5, 

 nearly as long as the petals. Style three-cleft above the middle. 

 Capsule as long as the calyx, 12-15-seeded. Seeds obscurely tuber- 

 culate-roughened. 



This is at once distinguished from the preceding species by its glan- 

 dular and viscid peduncles and calyx, its pointed sepals, its smaller 

 and shorter petals, and its petiolate leaves. It can hardly be a 

 smaller form of D. divaricata, H. B. K., which is said to have glabrous 

 peduncles, but viscid-pubescent pedicels; for the flowers are consi- 

 derably smaller than those of Holosteum umbellatum, the calyx itself 

 is glandular, and the peduncles and pedicels are not at all divaricate 

 nor reflexed.
