 the spatulate-oblong or linear leaves 2 or 3 lines long. The later specimcns are 3 

 or 4 inches high ; the principal length of the stem of one almost capillary inter- 

 node,.which is often 2 inches long; the lcaves very narrow and 6 lines long. The

 dulosis viscosis ; caule filiformi superne ramoso in cymam patentissimam multifloram 

 diliquescente ; foliis anguste linearibus sessilibus imis spathulatis parvis ; pediccllis 

 bracteas ovatas scariosas vix excedentibus flore brevioribus ; sepalis ovatis obtusis 

 3-nerviis leviter scarioso-marginatis petalis alte bifidis (lobis oblongis) brevioribus 

 capsulam 3 - 4-spermam adaequantibus ; seminibus l^viusculis. — • Mountains east

 from the preceding by the viscous glandulosity of the upper half of all the inter- 

 nodes (except the very short pedicels), by the larger petals, &c. ; from D. nodosa,
