20. HODGKINSONIA.^F. v. M. 

 (After Clement Hodgkinson.) 



Calyx-limb minute, 4-toothed. Corolla-tubes ovoid; lobes 4, very short, 

 obtuse (slightly imbricate ?) Anthers included, the filaments inserted near the 

 base of the corolla-tube. Ovary 2 to 4-eelled, with 1 pendulous ovule in each 

 cell ; style with as many linear-lobes as ovary-cells. Fruit a drupe, with a thick 

 hard 2 to 4-celled putamen. Seeds of Guettarda, the albumen present but 

 scanty. — Tree. Stipules interpetiolar, acuminate, very deciduous. Flowers 

 polygamo-dioecious, umbellate, on slender axillary peduncles. 



The genus consists of a single species, endemic in Australia. 



1. H. ovatiflora (flowers oval), F. v. M. Fragm. ii. 132 ; Benth. Fl. Austr. 

 iii. 420. A tree with slender branches, glabrous or the young shoots with a few 

 appressed hairs. Leaves petiolate, elliptical or ovate, obtuse or obfasely 

 acuminate, narrowed at the base, the veins not prominent, l^to Sin. long. 

 Peduncles slender, shorter than the leaves, bearing either a single umbel or a^so 

 a pair of lateral branches each with an umbel, each umbel on the male plant 

 with 10 to 12 flowers, on the female with only 3 to 6. Pedicels short. Calyx- 

 limb very small. Corolla in the males ovoid, almost urceolate, fully 2 lines long, 

 the lobes very short, thick, and obtuse, the ovary abortive. Corolla in the 

 females much smaller and nearly globular ; anthers small ; style short. Drupe 

 small, ovoid or globular.

21. CANTHIUM, Lam. 



(From Canti, the name of one species in Malabar.) 



Calyx-limb short, more or less toothed. Corolla-tube short or cylindrical ; 

 lobes 4 or 6, valvate in the bud. Anthers exserted or rarely included in the tube. 

 Ovary 2-celled, with 1 ovule in each cell, laterally attached near or at the top. 

 Style exserted, with a thick ovoid or mitre-shaped entire or 2-lobed stigma. 

 Fruit a globular compressed or didymous drupe, with 1 or 2 1-seeded pyrenes. — • 

 Shrubs either unarmed or with axillary thorns. Stipules interpetiolar, pointed, 

 with a broad base. Flowers in axillary cymes or clusters. 



A considerable genus, extending over tropical Africa, Asia, and the Pacific Islands. Of the 

 8 Queensland species, one extends into the Pacific Islands, the others appear to be endemic. 



This genus is included in Plectronia in B. and H. Gen. PI., and is so given in several of my 

 publications ; but as Sir J. D. Hooker and some other botanists still retain the genus Canthium, 

 I have considered it advisable to follow them in the present work. 



Stigma ovoid or mitre-shaped, entire or very shortly 2-lobed. Flowers 

 in pedunculate cymes, the lobes of the corolla longer than the tube. 

 Leaves broadly ovate, prominently penni veined and reticulate . . . . 1. G. latifolium. 

 Leaves oblong-elliptical to narrow-lanceolate, prominently and obliquely 



penniveined 2. C. attenuatum. 



Leaves ovate to oblong-elliptioal (2 to 6in. long), very smooth and 



shining, the veins scarcely prominent 3. C lucidum. 



Leaves oblong, rarely IJin. long, scarcely shining, the veins rarely 



conspicuous. Flowers about 3 lines long 4. C. oleifolium. 



Leaves ovate, rarely above lin. long, smooth arid shining. Flowers not 



2 lines long 5. G. huxifolium. 



Stigma subquadrate, notched or 2-fid. Flowers in cymes, 5-merous. 

 Fruit 3 to 4 lines, globose, ellipsoid or obovoid, oompressed-sub- 



didymous ; putamen rugose 6. C. didymum. 



Stigma thick, deeply 2-lobed. Flowers 2 or 3 together. Lobes of the 



corolla narrow, rather shorter than the tube. Leaves small ... . 7. C. vacciniifolium. 

 Stigma broad, peltate, entire. Flowers in sessile clusters. Lobes of the 

 corolla much shorter than the tube 8. C. coprosmoides.
