Aristolochia (Birthwort) N. O. Aristolochiaceae : — A large genus 

 of wide distribution containing plants with flowers more curious 

 than pretty. They are interesting because of the variety of the forms 

 of flowers. These entice the insects required for fertilization pur- 

 poses by emitting a most unpleasant odour. Only one species of the 

 genus has a pleasant odour, i.e. A. tricaudata, a native of Mexigo. 

 This species, however, is unsuitable as a climber growing more in the 

 nature of a shrub. TliC genus is of easy culture, most varieties 

 requiring very little pruning if any. Propagation by seeds or cuttings. 



A elegans: — One of the prettiest forms of all the Aristolochias. 

 Flowers solitary, produced on the young wood ; perianth a circular, 

 shallow saucer-like expansion, fully 3 inches across, grey and reddish- 

 purple with the throat dark velvet ; sack and tube greenish white. 

 Leaves reinform-cordate and glabrous. Moderately strong grower 

 and suitable for small trellis work. 



A. gigds var Sturtevantii : — This is the largest form of the genus. 

 Flowers gray, mixed with purple; perianth large and cordate with 

 purple veins going towards the tube which is darker in colour. Tube 

 inflated, limb large, cordate — ovate ending in a long tail often 18 

 inches long. Leaves downy, cordate-acuminnate. Height 10 feet. 



Banisteria N. 0. Malphigiaceae : — Many of the genus are very 

 ornamental shrubs or climbers, natives of South America. Flowers 

 usually yellow ; calyx 5 parted and petals furnished with long 

 stalks. Leaves simple and stalked. Propagation by cuttings or 

 layering. 



B. laurifolia : — Flowers yellow, having a slight resemblance to 

 Stigmaphyllutn or Oncidium. Free grower but moderately floriferous. 



Bauhinia (Mountain Ebony). N. 0. Leguminosae : — Showy ever- 

 green climbers and shrubs. Flowers racemose; petals 5, spread- 

 ing, oblong and rather unequal in size. Leaves two-lobed. As they 

 require to be of considerable age before they show to full advantage, I 

 only mention them in passing. Suitable for climbing large trees and 

 when in flower are beautiful. 



Beaumontia N. 0. Apocynaceae: — Very ornamental plants with 

 handsome flowers. Propagation by seed. 



B. grandiflora:—K robust grower suitable either for low trellis 

 or as a spreading plant on lawns. Flowers almost pure white, large 

 and trumpet shaped. Native of East Indies. 



Bignonia N. 0. Bignoniaccae: — This is a large genus of scan- 

 dent plants furnished with tendrils. The flowers are axillary and 

 terminal, usually panicled ; corolla with a short tube, a companulate 

 throat and a 5-lobed bilabiate limb. The leaves are opposite. The 

 genus contains some of the most beautiful of our climbers. Propaga- 

 tion by cuttings.
