FLOEIOULTUEE. 



HAUSSMANNIA JUCUNDA. 



H. jucunda (syn. Campsis jucunda, Muell. loc. cit.) a tall 

 glabrous woody climber. Leaves opposite digitate with three 

 leaflets articulate at the end of a petiole from 1 to 2 inches 

 long ; leaflets oval or elliptical, shortly acuminate, entire 

 membranous, penninerved 2 to 4 inches long, narrowed 

 into a short petiolule and the central leaflet occasionally 

 confluent with one of the lateral ones, but no simple leaves 

 in the specimen seen. Flowers in short racemes in the axils 

 of the terminal pair of leaves ; bracts small : bracteoles none. 

 Pedicels 2 to 3 lines long. Calyx very short. Corolla-tube 

 about 1 inch long ; lobes ovate, not 1 line long, hairy inside, 

 yellow and purple. Stamens hairy at their insertion below 

 the middle of the tube, shortly exceeding the corolla. 



It will be seen that the description of the genus is still 

 incomplete from want of the mature seed-vessel, which the 

 authors of the Flora of Australia never had an opportunity 

 of seeing. 



The plant having flowered at La Muette, Paris, we re- 

 quested M. Troupeau to fertilize the flowers, hoping to see 

 it fruit. But this gentleman writes * that its flowering was 

 the result of an accident, for the branch was strangled, 

 dissepiment transverse. Ovules numerous, in several rows causing the flowers to open prematurely and fall at unco, 

 on each placenta. Style with 2 ovate stigmatic lobes. Fruit the branch perishing soon after. .. However as the plant 

 unknown. j has many small branches, it is expected it will flower 



So far as is known at present, the genus is monotypic, I again in the Spring and furnish the materials for com- 

 and the species may be described thus : pleting the description. E. A. 



When we recorded the first-flowering of this curious 

 Bignoniaceous plant in Europe, we promised to give a more 

 detailed history of it, a promise we now proceed to fulfil. 



The genus Haussmannia was founded by Baron von Muel- 

 ler, of Melbourne, upon an Australian plant discovered by 

 Dallachy in Seaview Range, Rockingham Bay. The dedica- 

 tion was made in honour of Baron Haussmann, whose name 

 is inseparable from the enormous works in connection with 

 the remodeling and embellishment of Paris for the last 

 twenty years. 



It was first published in Mueller's Fragmenta Phytogra- 

 phiae Australiae, IV, p. 148, and subsequently in Bentham 

 and Mueller's Flora Australiensis, IV, p. 539. It is char- 

 acterized as follows : 



Calyx campanulate, truncate or minutely 5-toothed, Corol- 

 la tubular, incurved, dilated upwards; lobes 5, nearly equal, 

 obscurely arranged in two lips, induplicate-valvate in the 

 bud. Stamens 4, inserted in the tube, and longer than the 

 corolla, with a fifth small staminodium; anther-cells diverg- 

 ing or divaricate. Hypogynous disk cupular, completely 

 inclosing the ovary. Ovary short slightly compressed, the

Cajophoka coeonata, Hooker and Arnott, (Loasa 

 nata, Gill. mss. — Loasa absinthifolia, Presl. — Bli 

 bachia coronata, Hort.) — 

 Messrs. Haage and Schmidt, 

 of Erfurt introduced this plant 

 from Chili, and sent it out un- 

 der the last name cited above. 

 We prefer retaining the name 

 of Cajophora coronata, given 

 by Hooker and Arnott in their 

 Botanical Miscellany, vol. Ill, 

 p. 327, the genus Blumenbachia, 

 Kn;l. having previously been 

 established for some grasses 

 (Sorghum). We shall thus avoid all possibility of confusion 



in nomenclature. The plant belong 

 of Loasaceae. It is herbaceous, formii
