Vermont Shrubs and Woody Vines 141 



Since popular names have not been applied to these we have 

 coined them as follows : 



1. Tendril branches twining, disks few or none. .. .Tendril creeper. 



2. Tendril branches mostly ending in adhesive disks. 



Disk-creeper. 



TENDRIL* CREEPER. Pscdcra zitacea (Kneer) Greene. 

 This is the commonest form in Vermont, especially in way- 

 side thickets and old fence rows. While usually clambering over 

 low fences and thickets it mav ascend tall trees, clinging to any 

 available small support by the three to five slender twining 

 branchlets of the non-disk-bearing tendrils. This is the creeper 

 most commonly transplanted but either of the two disk forms is 

 to be preferred for many situations. The tendril creeper has 

 slightly larger leaves and fruit than the disk forms. 



disk-crEEpKR. Pscdera qiiinqne folia (L.) Greene. 



When a vine is desired to climb the side of a house, wall, tree 

 or similar surface, the disk-bearing varieties should be sought. 

 The type or smooth one is frequent, ascending tree trunks in 

 open woodlands. There is also a downv variety (var. hirsiita) 

 which occurs especially about cliffs, where it may be seen ascend- 

 ing vertical walls of bare rock with no support other than its 

 own disks. Tt often develops aerial rootlets which further aid it 

 in climbing. Apparently it is not so common as either of the 

 others and is said not to produce berries. Further observations 

 are needed upon this and other matters concerning the dis- 

 tribution and characters of these creepers. 



ROCK-ROSE FAMILY. CISTACEAE 



BE.ACTT-TiEATiTER. Hudsoma foinenfosa Nutt. 



This plant is also known as the downy hudsonia. As its Eng- 

 lish name implies, this is a heather-like plant which is found only 

 along the sandy beaches of Lake Champlain. So far as ob-
