54 ON SOTJTH-AMEETCAN APOCTNACEiE. 



Tabernamontana with 3 species : — 1, T. ciMfolia, with lanceolate leaves, in Hort. Cliff, 

 with a synonym of Plumier's plant ; 2, T. laurifoUa of Sloane ; 3, T. alternifolia, a 

 doubtful species of Rheede, Hort. Malab. After this Taberncemontana became the 

 receptacle for a host of heterogeneous species; so that in 184-4!, Prof. De Candolle 

 enumerated more than 90, after separating four under two new genera, Peschiera and 

 Bonafousia. Subsequently Prof. Muller removed these into Taberncemontcma, adding 

 nearly 4)0 new heterogeneous species. I have separated and classified most of these 130 

 species, retaining under Taberncemontana only those corresponding to the characters of 

 the Liunean type, which I carefully examined; these are easily recognized by their 

 hypocrateriform corolla, with sinistrorse aestivation, free slender stamens of a bluish 

 tinge, seated above the middle of the tube, their summits being more or less exserted. 

 The following may be considered to be the characters of the genus as here restricted.

A small tree, 15 feet high, with stout branchlets, having axils 2-3 in. apart, all lac- 

 tescent ; leaves rather large, oblong elliptic, cuneate or subacute at the base, somewhat 

 acute at the apex, sides often folded together, margins undulated, bright green above, 

 with about 12 pairs of immersed reddish nerves, yellowish opake beneath, with prominu- 

 lent midrib and nerves, 3-6| in. long, 2-2| in. broad, on broadly channelled petioles 

 with membranaceous margins, 3-6 lines long; panicles lateral, often opposite, with 

 4 branches, each bearing 2 flowers on short pedicels; sepals small, acute; corolla 

 hypocrateriform, tube 8 lines long; segments a little shorter, linear oblong, oblique, 

 sinistrorsely convoluted; stamens inserted below the mouth of the tube ; anthers linear, 

 caerulescent, half-exserted, IJ line long, biaristate at the base; disk shorter than the 

 2 acute oblong ovaries ; style, clavuncle, and stigmata as in the generic character ; 2 fol-
