134. Pyrus Iowensis (Wood) Bailey. 



Iowa crab-apple. A very promising crab ; much better than either of the pre- 

 ceding ones, and a distinctively western species. Has been found in Jackson, 

 Shannon, St. Louis and Washington counties. Much more common than these lo- 

 calities indicate, but apparently not distinguished from the last species. In this 

 species the twigs are large and densely tomentose, as are the leaves also, and the 

 fruit is much larger and covered with a gummy secretion. An abundant bearer, 

 this promises very much to become an important addition to our cultivated fruits. 



135. Pyrus Malus L. 



Common apple. This, or another cultivated species, has been found growing 

 wild in many places in the State, but at preaent I am unable to say what it is. 

 This genus and Prunus and Vitis are perhaps the most important to horticul- 

 turists. 



136. Pyrus Soulardi Bailey. 



Soulard crab . Of all our crab3 this is the most promising, and has already 

 been cultivated for its fruit, and proved to be of great value. Has been found 

 in St. Louis county, and there is a large crab found in Jackson county in the bot- 

 toms along the Missouri river that is said to be as large as a Little Rotnanite, 

 and is much used for making preserves by the country people. I have been unable 

 to secure specimens of this crab here, but it is probable that the Soulard crab ex- 

 tends up the Missouri river bottoms to the western part of the State. 



137. Aroma arbutifolia (L.) Ell. 



Choke-berry. A low shrub, with small, berry-like fruit, which is very astrin- 

 gent. Has been reported from Atchison county by Broadhead, but probably erro- 

 neously. This is Pyrus arbutifolia L. f. 



138. Amelanchier Botryapiuin ( L. f.) D. 0. 



Service-berry . A small tree or bush bearing edible fruit, and which promises 

 to become valuable in the future. It has only been reported from Greene county 

 as yet, but it is very probable that it is common to many other parts of the State. 

 All the Service-berries are susceptible of great improvement by cultivation. This 

 is Amelanchier Canadensia oblongifolia T. & G. 



139. Amelanchier Canadensis (L. ) Medic. 



Service-berry . A larger tree than the last, and appearing much more common, 

 but probably including two or more species as here given ; and until our forms are 

 carefully studied we cannot with certainty say what species we have, although it 

 is very probable that we have one or two more species than now known. Has 

 been reported from Atchison, Boone, Cape Girardeau, Clark, Greene, Howell, Jack- 

 son, Jefferson, Livingston, Madison, McDonald, Miller, Newton, Oregon, Pike, 

 Ripley, Shannon, St. Charles. St. Louis, Wayne, Webster and Wright counties. 

 Amelanchier Canadensis alnifolia of my Jackson county list was based on a cultivated 

 tree, and Bhould therefore be excluded from the list. 



140. Crataegus apiifolia ( Marsh.) Michx. 



Red-haio. A southern speciea*which extends up the Mississippi valley to the 

 southern part of the State ; has been found in Butler county. Bears inedible fruit.
