REPORT OF THE STATE BOTANIST 1903 51 



Clayey soil. North Greenbush. The plants which are here 

 referred to this species diverge so much from a rigid agreement 

 with the description of the species to which we have referred them 

 that it seems best to consider them a variety which may be called 

 var. divergens. 



It is characterized as follows : 



Leaves oval, serrate with blnnt gland-tipped teeth, divided 

 above the middle into 4-5 short narrow strongly pointed lobes each 

 side, petioles villose ; corymbs 5-10 flowered, stamens 10-18, anthers 

 whitish ; fruit globose or oval. 



The young shoots are villose tomentose. The flowers open about 

 the middle of May and the fruit ripens the last week in August 

 or early in September, which is two or three weeks earlier than in 

 the type. Only a single clump of this shrub was found. It ap- 

 proaches C. d e n s i f 1 o r a in its characters but dififers from it in 

 its more numerous stamens and in having the lower surface of the 

 leaves hairy on the midrib and principal veins. 



TENUIFOLIAE 



Fruit medium, oblong, pyriform or subglobose, crimson or scar- 

 let, nutlets 2-5 ; inflorescence glabrous or nearly so, stamens 5-20, 

 anthers pink, rose color or dark red; leaves membranaceous, gen- 

 erally pubescent on the upper surface when young, glabrous or 

 scabrous when mature. 



The three species here recorded may be tabulated as follows : 



Leaves ovate or oblong ovate C. ascendens 



Leaves ovate, oval or rhomboidal 1 



1 Calyx lobes hairy on the inner surface C. m a t u r a 



1 Calyx lobes glabrous on the inner surface C. d e 1 u c i d a 



Crataegus ascendens Sarg. 



Ascending thoni 



Rhodora, 5 : 141 



Shrub 6-10 feet tall with slender ascending branches bearing 



short, straight or slightly curved spines rarely more than an inch 



long; leaves thin, ovate or oblong ovate, at flowering time 1.5-2 



inches long, 8-15 lines broad, acuminate at the apex, rounded or 



cuneate at the base, finely and sharply serrate, with 4-5 acuminate
