Family 59. GROSSULARIACEAE. Gooseberry Family. 



Shrubs, wdth palmately veined leaf-blades; stipules none or adnata to the 

 petioles. Inflorescence racemose. Flowers regular, perfect. Hypanthium 

 more or less developed, from saucer-shaped to tubular. Sepals 5, rarely 4. 

 Petals as many as the sepals, small. Stamens as many as and alternate 

 with the petals, inserted in the mouth of the hypanthium. Gynoecium of 2 

 united carpels; ovary 1-celled, with 2 parietal placentae, inferior; styles 2. 

 Fruit a pulpy berry. 



Leaf-blades plicate (folded like a fan") in vernation: flowers regular; style not inclined. 

 Plant armed with nodal spines and usually also bristly. 



Pedicels not jointed near the flowers: brartlets if present enclosed in the bract: 

 hypanthium-tube well developed, deeply campanulate to cylindric. 



1. Grossclaria. 

 Pedicels jointed below the short stipe-like base of the flower, bearing the bracelets 



just below the node; hypanthium-tube short, saucer-sliaped. 



2. LiMNOBOTRYA. 



Plant unarmed: pedice's jointed just under the flowers; bractlets if present borne 

 just under tlie node. 3. Ribes. 



Leaf-blade.s convolute (rolled in) in vernation; flowers slightly irregular; styles somewhat 

 decUned. 4. Chrysobotrya. 



1. GROSSULARIA (Tourn.) Mill. Gooseberries. 



Shrubs, normally armed with simple or 3-forked nodal spines. Leaves in ours

 Hypanthium distinctly produced beyond the ovary; tube campanulate to cylin-

 glandular-hispid in G. setosa, but in species from other regions often spiny.
