may have received a name not known to me, but no accessible 

 description agrees with it. 



3. Y. Guatemalensis, Baker in Sa?inders' Ref7ig. bot. V. t. 

 313, Jul., 1872: elata ; foliis majoribus lanceolatis leviter con- 

 cavis planiusculisve ltevibus tenuioribus margine levissime 

 asperatis rnucrone concolore vix pungentibus deraum patulis ; 

 perigonii majoris segmentis lanceolatis sursum angustatis, interi- 

 oribus angustioribus longioribus ; filamentis apice patentibus 

 ovario prismatico-oblongo stylo brevissimo stigmatibusque pro- 

 funde bilobis patulis coronato brevioribus. 



From " Guatemala and Mexico" ; flowered in the Kew Gar- 

 dens in September, 1S71, whence through Mr. Baker I obtained 

 dried specimens. That plant was 8 feet high, with leaves 2^-3 

 feet long and 22-3 inches wide; panicle sessile between the 

 upper leaves, ovoid, 2-3 feet long ; flowers spreading apparently 

 5 inches, with narrow segments (3 inches long and f-i inch wide) 

 and, an unusual case, the inner ones narrower than the outer. 

 The most characteristic part of the flower is the ovary, which is 

 only twice as long (f inch) as it is thick, and bears on a short 

 style 3 deeply and acutely bilobed spreading stigmas ; the walls 

 of the carpels are unusually thick, the ovules themselves have the 

 diameter of others, but are very thick (0.5 mm.) indicating very 

 thick seeds and a pulpy fruit, which will probably be also found 

 short and thick. 



This species is said not to be rare in collections but seldom to 

 flower ; it seems that it is often taken for T. Draconis, and it 

 really resembles the typical figure of that plant by Dillenius. In 

 the botanic garden of Rome are several fine specimens named 

 thus, which I scarcely hesitate to refer here ; they are 15-18 feet 

 high, 1 foot in diameter at the enlarged base, not branched* ; leaves 

 22-2! feet long, 2-2 i inches wide, much contracted above their very 

 broad base, thin and somewhat flaccid or even pendulous, glossy 

 on the upper surface, delicately serrulate and with a very weak 

 point. The plants have not flowered. 

 * * Folia margine integra. 



4. Yucca gloriosa, Lin.: caule humiliore nunc ramoso ; 

 foliis lineari-lanceolatis versus basin latam angustatis supra plano- 



* Shoots have been cut off from the base! These cultivated plants are often altered in 

 appearance by trimming and by the removal of the dead leaves, which, left to nature, would 

 continue to cover the trunk for several feet below the living leaves.
