This snecies is distinguished from the others that have 2- 

 rsnked leaves, by the ascending leaves and long pedicels. But 

 in his ^evisiones, n, 96, ^aworth seems to have substituted a 

 different pl^^nt, vdth several varieties to it, havinf sessile or 

 subsessile flov^-ers. With the exception of the variety unca turn 

 quoted under G. uncatura (p. 535, 192l), L can find no clue to what 

 plants these may have been, but think it quite possible they may 

 have been hybrid forms raised from seeds produced in Surope, and 

 I feel sure that several of the forms nov; cultivoted under this 

 and vsrious other names are also of hybrid origin. 



"^e riant fimired as ^-■. heterophyllum, <^ackson in -a.ndrev;s 

 3ot. I^ep., V. 8, t. 540 (not of ^-evJOTth) , I suspect to have been 

 one of these seminal forms. It has very long leaves irregularly 

 incurved-hooked at the apex, pressed to the ground and flowers 

 about 27 in. in diameter on pedicels an inch or more long. Eavi- 

 orth (Rev., n. lOS) names this ^lant i-. angustum var. heterophy- 

 llum, but according? to his original description of M. angustum, 

 it has nothins in common with that species. It may be the same 

 as I', longum ver flpccidum, ^aw. , Synor,, p. 22. 



A, A. — Leaves not in two regular ranks, but pointing in 

 vrrious directions, the pairs crossing one anothei- oblicuely or 

 rarely at right angles. * 



* LeBves usually broader than thick, flat above, without a 

 hump or teeth on the flat face. 



11. G, tauriniim, i^. E, Br. Lepves oblicuely cruciate, 

 half-cylindric, obtuse, very thick, incurved, "less cruciate than 

 I', cruciatum, usually somewhat finger-like and nearly the size 

 of a finger, the younger incurved like the horns of ? bull,"
