FAMILY 59. GROSSULARIACEAE. GOOSEBERRY FAMILY. 



Shrubs, with palmately veined leaf-blades; stipules none or adnate 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; bractlets if present enclosed in the bractr 

 hypanthium-tube well developed, deeply campanulate to cylindric. 



1. GROSSULARIA. 



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

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



2. LlMNOBOTRYA. 



Plant unarmed; pedicels jointed just under the flowers; bractlets if present borne 



just under the node. 3. RISES. 



Leaf-blades convolute (rolled in) in vernation; flowers slightly irregular; styles somewhat 

 declined. 4. CHRYSOBOTRYA. 



1. GROSSULARIA (Tourn.) Mill. GOOSEBERRIES. 



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

 rounded or reniform, or more or less pentagonal in outline, 3-5-cleft and crenate 

 or dentate. Flowers bracteate in few-flowered racemes; pedicels not jointed. 

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

 dric. Fruit a berry, with rather tough skin, in ours smooth, only somewhat 

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