8 I. RANUNCULACE^ (oliver). ' {^Clematis. 



C. aanzibarensis, Boj. in Loud. Eort. Brit. 228, I do not know. I have not- seen 

 any suflBicient description of it. 



2. THALICTRUM, Linn. ; Benth. and Hook. f. Gen. PI. i. 4. 



Sepals 3 to 5, imbricate in sestivation, early deciduous. Petals 0. Sta- 

 mens 5-8 or more numerous. Anthers linear or linear-oblong. Carpels 

 solitary or several (5-10), each with a solitary, pendulous ovule. Achenes 

 sessile or stipitate ; stigma deciduous or persistent. — Perennial herbs with 

 alternate, much-divided leaves with sheathing bases. Flowers usually pani- 

 cled, rather small, gi-eenish, purplish, yellowish, or white. 



A considerable genus of temperate and alpine countries, most numerons in species in 

 Europe and Asia ; between the tropics confined to mountainous or elevated regions. One of 

 the following species is endemic and presents some remarkable peculiarities. 

 Carpel solitary, stipitate. Style elongate-filiform, longitudinally 



stigmatose, persistent. Fruit-pedicels hair-like, very long . . 1. T. rhynchocarpum. 

 Carpels several (7-10), sessile ; stigma broadly ovate or subcordate, 



with revolute margins, so as to appear conical and sessile upon 



the young achene. Fruit-pedicels not lengthening 2. T. minus. 



1. T, rhynchocarpum, Bill, et Rich, in Ann. Sc. Nat. Ser. 2. xiv. 

 262. Stem erect, terete, glabrous, 4-10 ft. high. Leaves 2-4-pinnate; 

 leaflets simple or ternate, usually ovate or more or less cordate, 3-lobed or 

 broadly 3- 7 -toothed; teeth obtuse or minutely apiculate, glabrous. Panicle 

 diffuse, with numerous small, greenish flowers upon hair-like pedicels, which 

 grow out after flowering to 1-6 in. in length. Sepals 3 or 4, obovate or 

 broadly elliptical. Stamens usually 5-10, with apiculate anthers. Ovary 

 shortly stipitate. Achene strongly 3 -ribbed on each side, tapering below 

 into a slender stipe nearly its own length, above into the elongate style. —

Occurs also south of the tropic in Orange Free State and Katberg. 



One of the most remarkable species of the genus, differing from the more typical forms 

 in the solitary carpel and long persistent style, as well as in the remarkably long, capillary 

 fruit-pedicels. 



2. T. minus, Linn. ; DC. Prod. i. 13, var. scabrivena. A glabrous or nearly 

 glabrous herb, attaining often several feet in height, with an erect or some- 

 what zigzag, glabrous, smooth or slightly furrowed stem. Leaves 2-3-pin- 

 nate ; leaflets 3-lobed or variously incised, rather glaucous below, with the 

 prominent veins scattered with microscopic setae. Panicle leafy. 



Nile Iiand. Abyssinia, Schimper! 



A variable species, widely spread in Europe and temperate Asia. Many of the more 

 marked varieties have been distinguished as species. 



T. Schimperianum, Hochst.^ described in Schweinfurth's Fl. ^thiop. 78, I take 

 to be also a variety of T. minus. It is said to have the /fla^5 of T. ^^a-wo«<?«, Bernh. 

 Collected in the Bachit Mountain, Abyssinia, by Schimper.
