An evergreen twiner Avith pink flowers, allied to M. Li/r/isUon 

 itself, but easily distinguished by the whitish hairs on the under side 

 of the leaves, which are markedly acuminate, and b}^ the stipules. 

 Leavf's 3-5 cm. X 1'2-1'8 cm., with petiole not attaining 3 mm. ; 

 sheath of stipules 2 mm. or deeper, the acuminate free portion — 

 sooner or later deciduous, 2 mm. or longer. Ovary rather more than 

 2 mm. long in the flower ; calyxAoh^^ nearly the same length. 

 Coro//rt-tube 1'2 cm. long nearl}^, lobes 2-8x2 mm. The globose 

 capsule is 4 mm. long and wide. 



33. M. thysanophoi-a, sp. nov. 



Fratex volubilis, caule in novitate filiformi sparse hirtello glabres- 

 cente subtereti striato. Folia inter mediocra plana membranacea 

 herbacea, uti-inque prajsertim in juventute sparsiuscule hirta, elliptica 

 acuminata utrinque acuta, j^ef/o/o tenui subelongato ; vence primariie 

 subtus prominuliB lateribus (utrinque ca. 8) pro rata crebrse, rete 

 tamen interveniente vix manifesto ; stipulce membranaceam in vaginam 

 brevissimam connatse mox reflexam margine irregulariter setis nume- 

 rosis fimbriatam insequalibus. Flores in paniculis dispositi vel um- 

 bellis cymosis alaribus inter minores, hypocrateriformes, pedicellis 

 s,upe longiusculis filiformibus cum ovario campanula to sub anthesin 

 nonnunqaam flavo-pulverulentibus tardius glabrescentibus. Calyx ad 

 basin laciniis in 4 late ovatis divisus apice ssepe obtusis parvis glaber- 

 rimis. Corollcd tubus pinguis tamen brevis cylindricus extus gla-

 Aliiinl to 31. Lygistum, this species is notable for the peculiar 

 stipular structure, and the broad blunt calyx-lobes. Leaves Z'5-d ctu. 

 X 1'3-1"9 cm., the petiole as much as 7-8 mm, long ; sheath of 

 stipules barely 2 mm. deep, the setae of the marginal fringe as much 

 as 2'5-3 mm. in length. Fechincle 1-2 cm. long; pedicels 3-8 mm. 

 Ovary scarcel}'' 2 mm. long ; c<77y.r-lobes rather longer than 1 mm., 

 and of the same breadth, or broader. Corolla-twhQ not exceeding 

 5 mm., lobes 2 X 1*7 mm.

This di:ffers from M. Lygistum especially in its truncate stipules 

 and much smaller corolla. Both species have strongly-marked reticu- 

 lation, especially on the low^er surface of the leaves.
