528 Rosaceae Malus 



1. Gillenia stipulata (Muhl.) Trel. (Porteranthus stipulatus (Muhl.) 

 Britt.) Indian-physic. Map 1091. 



The report in Coulter's Catalogue by Barnes from Tippecanoe County I 

 am regarding as an error. There is, however, in the herbarium of the 

 University of Michigan a specimen collected in Madison County by Charles 

 Piper Smith, July 22, 1904. It is infrequent to very local except in the 

 knob area where it is most frequent. It grows in dry soil and is usually 

 found on the crests and slopes of chestnut oak and post oak ridges. In the 

 southwestern part of Posey County it is found in the post oak flats. The 

 leaves of this plant are mostly trifoliate but often those at the base have 

 pinnatifid leaflets and those below the inflorescence may be only three- 

 lobed.

 See excluded species no. 301, p. 1058. 



3338A. MALUS Mill. Apple 



Margins of leaves of sterile branchlets generally more incised than those of fruiting 



branchlets; teeth of leaves of both sterile and fruiting branchlets variable in size; 



pedicels slender, 1 mm or less in diameter at flowering time; sepals about 2 mm 



wide at the base. 



Older leaves generally glabrous or nearly so beneath at flowering time, those at the 



ends of the branchlets usually more or less tomentose, all of the leaves glabrous 



at maturity or with some pubescence on the principal nerves. 



Outer surface of calyx glabrous or nearly so at flowering time. . . .1. M. coronaria. 



Outer surface of calyx tomentose at flowering time 



la. M. coronaria var. dasycalyx. 



Older leaves as well as those at the ends of the branchlets densely tomentose be- 

 neath, the tomentum persisting on most of the leaves until maturity 



2. M. ioensis. 



Margins of leaves of both sterile and fruiting branchlets similar in shape; teeth of 

 leaves of both sterile and fruiting branchlets similar in size and shape; pedicels 

 stout, 1.4-2 mm in diameter at flowering time; sepals 3-4.5 mm wide at the base. 

 (See excluded species no. 303, p. 1058.) M. pumila. 



1. Malus coronaria (L.) Mill. (Mains glaucescens Rehd. and Malus 

 lancifolia Rehd. of Deam, Trees of Indiana.) Wild Sweet Crab. Map 

 1092. Found throughout the state in various kinds of soil of varying 

 amounts of moisture. It generally grows in colonies, mostly in open wood- 

 land, clearings, and wood pastures and along roadsides and fences. 



The genus Malus of the "Trees of Indiana" was written by W. W. Eggle- 

 ston. A careful restudy of my specimens convinces me that those using 

 a local flora of this kind will be best served by regarding this species as 

 polymorphic in many of its parts. Specimens can be found that show 

 wide differences but these can be connected by intermediates. 



The synonymy of the species is involved and is omitted unless it ap- 

 plies to names used in "Trees of Indiana" by Deam.
