Buchnera.] 
Leaves all narrow, the lower ones oblong, the upper ones linear, mostly 
acute. Corolla glabrous. 
Corolla-tube 3 to 4 lines long 3. B. linearis. 
Corolla-tube not 2 lines long 4. B. tenella. 
Leaves all narrow and obtuse, usually hoary, the lower ones oblong. 
Stems simple. Corolla glabrous outside 5. B. gracilis. 
Stems branching. Corolla pubescent or hispid outside 6. B. ramosissima- 
1. B. tetragona (4-angled), R. Br. Prod. 437 ; Bentli. FI. Austr. iv. 514. 
Erect tall and stout, some specimens simple and fully 2ft. high, others smaller 
and branched, and all quite glabrous. Lower leaves ovate or oblong, obtuse, 
coarsely and irregularly sinuate toothed, narrowed into a short broad petiole and 
sometimes 3 to 4in. long, upper ones lanceolate and sometimes all under 2in. 
Spikes usually 3 to 5 together, almost sessile within the last pair of leaves, very 
thick and 1| to 2in. long, the flowers densely imbricate in 4 rows, each one 
sessile within a bract 2 to 3 lines long, much broader than long, very shortly 
acuminate in the middle. Bracteoles narrow, complicated, acuminate, as long 
as the calyx. Calyx, 2^ lines, not at all or scarcely compressed, the lobes 
narrow, very acute, nearly as long as the tube. Corolla-tube slender, nearly 
4 lines long, the lobes broad, nearly equal, spreading to 3 or 4 lines diameter. 
Capsule oblong, rather longer than the calyx.— Benth. in DC. Prod. x. 495. 
Hab.: Endeavour River, Banks and Solander ; Cape York and the islands of Torres Straits. 
Allied to the E. Indian B. tetrastieha, but readily distinguished by the smoothness of the 
whole plant as well as by the calyxes and bracts. — Benth. 
2. B. urticifolia (Nettle-leaved), R. Br. Prod. 437; Bentli. FI. Austr. 
iv. 514. Scabrous-pubescent or nearly glabrous. Stems erect and simple or 
branching and slightly decumbent at the base, rather slender, often above 1ft. 
high. Radical and lower leaves almost rosulate at the base of the stem, obovate 
or broadly oblong usually sessile, obtuse, entire, or slightly sinuate-toothed, 1 to 
14 or rarely 2in. long ; stem leaves narrower, the upper ones linear or linear- 
lanceolate, acute. Flowers purplish or nearly white, in slender interrupted 
terminal spikes. Bracts mostly ovate, acute, ciliate, about half as long as the 
calyx or the lower ones longer and narrower ; bracteoles similar, but smaller. 
Calyx narrow, rarely 2 lines long, the teeth acute. Corolla glabrous outside, 
the tube slender, not twice as long as the calyx. Capsule oblong, obtuse, either 
equal to or rather exceeding the calyx.— Benth in DC. Prod. x. 496 ; Endl. 
Iconogr. t. 78. 
Hab.: Common along the coast, B. Brown and others ; from Cape York, Dcemel, to Morelon 
Bay, F. v. Mueller. 
The common E. Indian B. hispida differs chiefly in being much more hirsute. The African 
B. leptostachya can scarcely be distinguished from some forms of the species, which might 
indeed include, as slight varieties, the following four. — Benth. 
3. B. linearis (leaves narrow) R. Br. Prod. 437 ; Benth. FI. Austr. iv. 515. 
Scabrous-pubescent. Stems erect, simple or slightly branched, often exceeding 
lft. the upper leaves linear and acute as in B. urticifolia, and sometimes the 
lower ones scarcely broader, but usually those near the base of the stem are 
oblong, obtuse, often obscurely toothed, narrowed into a petiole and not sessile 
nor rosulate. Flowers and fruit the same as in B. urticifolia, or rather larger. 
Benth. in DC. Prod. x. 497. 
Hab.: Islands of the Gulf of Carpentaria, R. Brown. 
Var. asperata. B. asperata, R. Br. Prod. 438; Benth. in DC. Prod. x. 496, appears to be 
a rather larger, coarser, and more scabrous form of the same species. — Bustard Bay and Bay of 
Inlets, Banks and Solander. 
4. B. tenella (slender) R. Br. Prod. 437 ; Benth. FI. Austr. iv. 515. 
More slender than the other species, simple or branched, often lft. high or 
more, the foliage and the lower part of the plant sparingly hirsute, the upper
