Tillandsia (including Vriesia). Baker's Jimitations are 
much the same; but Mez keeps up both Tillandsia and 
Vriesia ; the latter having free petals ; the former connate or 
closely conglutinated petals. Apart from this, a very large 
proportion of the Bromeliaceae in cultivation have names 
under at least two genera. : 
Mez has also revised the synonymy of som, of the allied 
species of Puya. Lindley adopted the name caerulea for 
the plant he figured and described in the place cited above, 
believing it to be the same as that mentioned in Miers’s 
Travels in Chile and La Plata, vol. ii. p. 531, as Pourretia 
caerulea; but Mez refers the latter to Pitcairnia alpestris, 
Poepp., to which he also refers Puya Wahytei, Hook. f. 
B. M. t. 5732. Pourretia rubricaulis, Miers, Travels, p. 531, 
he regards as the same as Pitcairnia caerulea, Lindl. 
He distinguishes Puya, Molina (including Pourretia, 
Ruiz and Pavon), from Pitcairnia, L’heritier, by the com- 
pletely superior ovary, and he divides Puya into three 
subgenera: Hupuya, Pitcairniopsis and Pourretia. 
Dersoription.—Shrub, flowering more than once, including 
inflorescence about 3 ft. high. Stem short; branches few. 
Leaves numerous, crowded, stiff, linear, largest 20 in. long, 
tapering upwards and very narrow, margin furnished with 
small prickles, }-3 in. apart and directed upwards, finely 
striated, underside clothed with microscopic stellate scales. 
Inflorescence terminal, erect ; pinnately paniculate, 18-20 in. 
high ; scape rather slender, clothed with brown linear bracts 
1-2 in. long, which shrivel and persist; lateral branches 
about twelve, spreading in all directions, deflected, 5-8 in. 
long, 20-—25-flowered. Flowers spirally arranged, shortly 
stalked, 4-3 in. apart. Sepals 3, green, lanceolate, 1-1} in. 
long, acute, persistent. Petals 3, deep violet, oblong-spathu- 
late, about 2} in. long, obtuse, shortly recurved, furnished 
with two scales inside near the base. Stamens 6, nearly 
equalling the petals; anthers orange. Style included.— 
W. Borrine Hemstey. 
Cuitivation.—Puya and that section of Piteairnia which 
Mr. Baker separated under the name of Puyopsis are all 
hard prickly-leaved plants which appear to be happiest 
when cultivated under the same condition as Cacti, Agave,
