19161 Fernald,— A Variety of Andromeda glaucopylla 101 



writer were botanizing on the west coast of Newfoundland, it was a 

 great surprise to find the species, very dwarfed but freely fruiting, on 

 the limestone barrens about Ingornachoix Bay. In fruit the material 

 from the limestone barrens seemed inseparable from the dwarfest ex- 

 tremes of the common plant of acid peats; but in 1914 Mr. Harold 

 St. John and the writer were fortunate enough to find a dwarfed plant, 

 which was quite similar in aspect to the Ingornachoix Bay material, 

 forming extensive mats on the limestone tableland of Table Mountain, 

 back of Port a Port Bay. There the tiny shrub was associated, as it 

 was about Ingornachoix Bay, with very characteristic calciphiles: 

 Equisetum variegatum Schleicher, Poa alpina L., Kobresia caricina 

 Willd., Juncus triglumis L., Tofieldia palustris Huds., Salix vestita 

 Pursh, Anemone parviflora Michx., Lcsquerella arctica (Richardson) 

 Watson, var. Purshii Watson, Saxifraga oppositifolia L., Potentilla 

 nivea L., Dryas integrifolia Yahl., Viola nephrophylla Greene, Lobelia 

 Kalmii L., Erigeron hyssopifolius Michx., etc. — an association of 

 plants which we never find in the acid peats and sphagnous bogs 

 where typical Andromeda glaucophylla abounds. 



On Table Mountain the Andromeda was in full flower and we were 

 at once impressed by the fact that the corolla was much shorter than 

 in the familiar bog-shrub, and oblate-globose in form, shorter than 

 broad; the longer corolla of typical A. glaucophylla being ovoid-urceo- 

 late. In typical A. glaucophylla, furthermore, the anthers are pale 

 brown in color; in the Table Mountain plant purple or purplish- 

 black and unusually short, while the filaments, too, are shorter and 

 broader-based than in the plant on the acid bogs. One other char- 

 acter, apparently post mortem, is of interest. In practically all the 

 specimens of the Table Mountain plant with oblate-globose corollas 

 and purple anthers, the corollas, under pressure, have split deeply 

 into five lobes, so that in the herbarium-material the corollas have 

 become campanulate, thus strongly suggesting those of Cassiope. 



writer to be no real doubt thai Link was describing the common American representative of the 



Kuropean species; but on account of (lie different interpretation by Dr. Small, it has seemed 

 wise to have the type of Alton's var. lalifolia, upon which A . glaucophylla rests, examined. 

 This was kindly undertaken by Mr. S. F. Blake, who in a letter of February 3, 1915, wrote: 

 "a lalifolia Ail. Type (ex. llort. Pitcatrne, 1778) is A. glaucophylla of Manual, ed. 7, with 

 oblong slightly revolute leaves tomentulosc beneath, the larger 3-4 cm. X 6-10 mm. Tracing 

 sent." 



Whether Link had material which was essentially different from that of Alton cannot now be 

 readily determined, hut in view of the emphasis given by Link to the short peduncles and the 

 clear identification of Alton's var. lalifolia, there seems no reasonable doubt that A. canescens 

 Small is A. glaucophylla Link,
