522 Grossulariaceae . Grossularia 



Ovary glabrous, rarely pubescent or with stalked glands. 



Stamens much exserted, more than twice as long as the petals, often exceeding the 

 sepals; ovaries glabrous. 

 Nodal spines usually present, 1-3, generally 8-20 mm long, occurring at almost 



every node 2. G. missouriensis. 



Nodal spines none or single, rarely 3, about 5 mm long. (See excluded species 



no. 295, p. 1057.) G. rotundifolia. 



Stamens not exserted, at most not more than the length of the petals. 



Calyx pubescent; nodal spines 1-3, stout, usually 7-15 mm long, occurring at 

 almost every node; ovary green or yellowish to red, pubescent and glandular- 

 bristly or glabrous (See excluded species no. 294, p. 1057.) G. reclinata. 



Calyx glabrous. 



Young branchlets generally bristly; nodal spines present, usually 3. 

 Calyx tube cylindric-campanulate; peduncle elongated. (See excluded species 



no. 296, p. 1057.) G. setosa. 



Calyx tube campanulate; peduncle scarcely exceeding the bud scales. (See 



excluded species no. 293, p. 1056.) G. oxyacanthoides. 



Young branchlets not bristly, rarely some bristles at the base of vigorous ones; 

 plants rarely with nodal spines, which, if present, are subulate and 5-10 

 mm long 3. G. hirtella. 



1. Grossularia Cynosbati (L.) Mill. (Ribes Cynosbati L. of Gray, Man., 

 ed. 7.) Pasture Gooseberry. Map 1080. Infrequent to common through- 

 out the state except the southwestern part, from which there are no records 

 or specimens. The species prefers a moist, rich soil and is found generally 

 in woodland. In the southern part of the state, however, it is generally 

 found in the crevices of rocks on rocky, wooded slopes along streams.

2. Grossularia missouriensis (Nutt.) Cov. & Britt. (Ribes gracile 

 Michx. of Gray, Man., ed. 7.) Missouri Gooseberry. Map 1081. This 

 species has been reported from Hamilton, Kosciusko, Lake, Marion, St. 

 Joseph, and Tippecanoe Counties. In the herbarium of DePauw Uni- 

 versity there are specimens from Jasper, Putnam, and Vigo Counties. My 

 specimens are mostly from the central and western counties where I found 

 them in dry soil, usually on the bluffs of streams. The Henry County 

 specimen was found in a dry woods and the one from Tippecanoe County 

 was found with skunkcabbage in a springy place.

3. Grossularia hirtella (Michx.) Spach. (Ribes oxyacanthoides L. in 

 part, of Gray, Man., ed. 7.) Low Wild Gooseberry. Map 1082. This 

 species is restricted to the northern counties and is found only in wet 

 places, mostly in tamarack bogs. It is infrequent to very rare in the area 

 of its distribution. 



The extreme variability of this species, especially in the shape of the 

 leaves and in the amount of pubescence on their under surface, has led to 

 the naming of varieties of it. Writers tell us that the bases of the leaves 

 of this species are generally more or less cuneate and that the bases of 

 the leaves of Grossularia oxyacanthoides are truncate or cordate. 

 I have two specimens with the bases of the leaves cordate but I think, 

 because of other characters, that they belong to this species. I have one
