flowers in clusters on old twigs, pods slender with slight constriction between the 

 seeds. 



II. Caesalpineae (91/1100), a series in which the Pea-type of flower is 

 infrequent. Examples of extreme zygomorphy occur, but practical actinomorphy 

 may be retained, or parts may be further reduced : cf. as available : — 



Cereis Siliquastrum, Judas Tree, of S. Europe : Flowers on bare branches 

 in clusters on spur-shoots before the leaves, pink and Pea-like, f in. ; stamens all 

 free ; a definite perigynous receptacle as nectary-cup, the siandard-petal enclosed 

 within the wings, as these are inside the keel. Pods flat, 3-4 in., hanging from the 

 branches. 



Haematoxylon campeehianum, Logwood; small tree of W. Indies, cult.; 

 Flowers actiiiomoiphic, 8 mm. ; petals equal, }'ellow ; stamens 54-5, but one carpel 

 only, and the fruit one-seeded : in some respects possibly the most elementary form 

 of the group. 



Hardwickia binata, Anjan ; a large gregarious timber-tree of dry deciduous 

 forest of S. India, deep-rooted; Leaflets 2 -only, 1-2 in. long, with terminal pointed 

 rudiment : Flowers small, greenish-yellow, 15 mm., in lax racemes, apetalous; sep. 5, 

 stamens .^4-5, one carpel; fruit a flat pod, 2\ in., indehiscent with one seed at 

 distal end, spinning-type : the limit of simple reduction. As extreme cases, cf. : — 



Cassia Fistula, a tree of deciduous forest, and commonly cult. ; leaves 

 pinnate ; with pendulous racemes of yellow flowers (suggesting Laburtium) : stamens 

 differentiated, 3 long anterior dehiscing by slits, 4 with shorter filaments and dehiscing 

 by pores, 3 posterior minute and sterile. Pod cylindrical, large, black, 1-2 ft., with 

 seeds in black resinous pulp, medicinal and economic ; animal-dispersed. 



C. aurinilala a shrub on dry stony soils gives tannins. 



Poineiana regia, Gold INlohur Tree, African, cult., with erect showy panicles 

 •of scarlet flowers; pods flat, 1-2 ft. 



Tamarindus indiea, a fine tree of C. Africa, naturalized and cult. ; Lax 

 racemes of 10-15 flowers; 3 post, petals only functional, 2 ant. minute; 3 post, 

 stamens large and curved forwards, others as vestigia only. Pods as thick husks 

 with brown acid pulp, fibres, and small brown seeds. 



Amherstia nobilis, evergreen tree of S. Burma, cult. ; leaves hang vertically 

 when young. Inflorescences as pendulous racemes, many flowered ; prophylls large 

 and scarlet, 2 posterior sepals give a hooded segment, others simple ; 3 post, petals, of 

 which the median is a flag-segment with broad waved lamina with crimson and 

 yellow blotch at end, 2 anterior as rudiments. Stamens g -t- 1 ; nied. post, stamen 

 reduced ; ,5 anterior long, and 4 short : Perigynous receptacle extended 40 mm. to 

 a narrow nectarj'-tube ; honey-bird pollinated. Pod flat and linear, 7 in. 



Bauhinia Vahlii, a gigantic liana-form, destructive to Sal, &c.: stem to 100 ft. 

 long, and 1-2 ft. diam., growing 50 ft. a year, with anomalous thickening. Leaves to 

 18 in., ' cleft ' \ down : Flowers creamy-white, 5 petals and 3 fertile stamens; petals 

 hairy, i^ in. long. Pod 9-18 in., long, broad and flat, hair}', woody and bursting 

 explosively. 



B. variegata, a middle-sized tree of dry deciduous and hill-forest, cult. ; Flowers 

 large and showy, fragrant, white and pink : standard-petal darker or variegated, 

 conspicuous, with 5 functional stamens. Pods long and slender. 



III. Mimoseae (30/1000): a wholly distinct type of floral organization, 

 familiar in Acacia Jcalbata (Mimosa), the Australian Silver Wattle. Foliage bi- 

 pinnale, evergreen ; inflorescence as panicles of small globular capitula, 8 mm., 

 fragrant ; flowers not all perfect, minute, with a dense cycle of 30 stamens, slender 

 style, reduced valvate sepals and gamophyllous petals ; actinomorphic, pollen in 

 packets. Fruit a pod (2-3 in.) dehiscent, seeds non-endospermic. Elementary 

 forms have larger flowers on a similar plan in more racemose spikes. 



Prosopis spicigera, Jhand : a stunted thorny tree, gregarious in dry tracts of 

 Punjab, &c., persisting by deep root. Flowers in slender spikes ; stamens 10, anthers
