108 NINTH REPORt. 



hirsutum is seen. The exceedingly rare Coeoglossum tracteatum has been 

 found twice. Blephanglottis ciliaris once. B. psycodes is common. Coral- 

 lorhiza corallorhiza and C. odontorhiza may be found by patient search. 

 Moehringia, ThaHctrum purpurascens, Cardamine purpura, Rubus Ameri- 

 eanus and R. his):)idus and Agrimonia parriflora, all these will be found. 

 The latter is equally at home on barren and dry hillsides, where, if anything, 

 it is even more vigorous. Another interesting plant is Polygala viridescens, 

 found in one such habitat. Solidago rugosa, Helianthus gigantens and 

 Carduus mulicus will suffice to finish this enumeration. 



The plants of the lakes, ponds and stagnant streams may be considered 

 as a single association, although each body of water has one or more peculiar 

 features. All of these waters have many Potomogetons, the most striking, 

 P. praelongus growing often in 12 feet and forming miniature sub lacus- 

 trine forests, haunts of sunfish and the bane of the troller. Seirpus validus 

 covers a very large area of Magician, its outer margin almost exactly marking 

 the fathom line. S. Americanus forms a zone in one foot of water and makes 

 a very dense growth, difficult to penetrate with a boat. Two other plants 

 forms isolated patches in Lake Magician. Eleocharis interstincta covers 

 nearly an acre near the outlet, and Juncus sp. makes dense mats in the shoals 

 of the southeast shore. Naias hexilis is very abundant in most of the lakes, 

 forming beautiful tufts in shoal water, but becoming much elongated in deep 

 water, where it is found to a depth of 15 feet. N. gracillina is common in 

 Crooked Lake and is very unlike its more vigorous relative. It may be in 

 place here to note tlie immense growth of Chara in the dee]) waters of Ma- 

 gician, having been found at as great a depth as 30 feet. It seems to be the 

 marl producer, as this lake has a marl bottom, and entirely different, there- 

 fore, from all the others in the district. 



In Cable Lake is a deep water growth of Isoetes echinospora Braimi that 

 may be gathered in large quantities after storms. I have not l^een able to 

 find this plant in situ, and have a theory that it may be dislodged from the 

 deep by the blue-gills, so very abundant in this lake. This place is the home 

 of the finest strain of Castalia odorata I have ever seen, the richness of the 

 leaf coloration being very remarkable, actually becoming a clear, deep, uni- 

 form red, totally unlike the mere tinting found in Magician forms. Immense 

 numbers of Eriocaulon septangulare grow from the shoals of both Cable and 

 Dewey well up onto the beach. In both, also, in one or two inches of water 

 grow three Utricularas, U. gibba, U. resupinata and I', corunta, the resu- 

 pinata occurring by the thousand and forming a distinct band of growth. 

 In Silver Creek, the Magician outlet, are found two more of this genus, U. 

 vulgaris and U. biflora, the latter occupying a small area about 10 x 30 feet. 

 . Returning a little, Castalia tul)erosa grows by myriads in this same stream, 

 and Brasenia is common. Here again a very striking difference occurs be- 

 tween this stream form and that found in Round Lake, ^^•here the leaves are 

 fully twice the size and richly colored red below, and with enough mucilage 

 on their lower surface for a dram vial. Equisetum palustre abounds and 

 Seirpus subtcrminalis forms dense matted growths. 



In De\^■ey Lake, covering an area of a half acre, is found a form of Poly- 

 gonum emersum, with most brilliantly red and striking flowers, contrasting 

 well with the usual rose or pink of the species. Philotria, the genuine Cana- 

 densis, is very rare except in Pipestone ditch, where it is fine and vigorous. 

 Here also Myrioi)hyllum verlicillatum is rare. Cerabophyllum has been 

 found only once in Magician. 



Coming to our Fifth District, the oak and hickory growth, we find the
