NEW GUATEMALAN BROMELIACE.E. 305 



fruit can be found on the Sugar-cane ; it is the same with the 

 seed-leaf, which we understand to be the cotyledon, unless the 

 Secretary means the cotyledonary sheath, for it is the first dull- 

 coloured amplexicaul leaf which is present at the base of the plant 

 in our specimen." 



In the plate which accompanies the paper, a spikelet is figured 

 with the young plant growing out from between the glumes. The 

 figure is from a dried specimen, and nothing is indicated in the 

 young plant except the two primary leaves rolled up. 



NEW GUATEMALAN BB.OMELIACEM. 

 By J. G. Baker, F.R.S. 



For the opportunity of examining a small set of Bromeliacece, 

 gathered by himself in Guatemala, I am indebted to John Donnell- 

 Sinith, Esq., of Baltimore, who has recently reported on, in the 

 American ' Botanical Gazette,' and distributed a fine collection of 

 plants made by Von Turekheim in the same country. 



iEehmea (Hohenbergia) isabellina, n. sp. — Leaves lorate, 

 2 ft. or more long, 2-2ifn. broad, moderately firm, glabrous above, 

 thinly lepidote beneath ; apex deltoid-cuspidate ; marginal spines 

 large and pungent, lower ^ in. long. Peduncle stout, l£ ft. long, 

 with few large ascending scariose lanceolate bract-leaves. In- 

 florescence a narrow panicle 2 ft. long, with numerous short simple 

 deflexed branches 1-2 in. long ; lower branches much longer and 

 bipinnate, subtended by large red lanceolate bract-leaves ; rachis 

 densely pubescent ; flowers laxly disposed ; flower-bracts ovate- 

 acuminate, \ in. long. Sepals ovate, imbricated, ^ in. long, not 

 distinctly cuspidate, rather longer than the globose ovary. Petals 

 protruded, £ in., probably yellow. — Boca del Polochic, dept. Ysabel, 

 alt. 200 ft., Donnell- Smith ±824! Intermediate between M. laxiflora 

 Benth. and pyramidalis Benth. 



• 2E. (Lampbococcus) Donnell- Smithii, n. sp. — Leaves lanceo- 

 late, very rigid, above 2 ft. long, 3 in. broad low down, glabrous 

 above, obscurely lepidote beneath, narrowed gradually to the point ; 

 marginal teeth minute, crowded. Peduncle stout, above a foot 

 long, with several pale scariose ascending lanceolate bract-leaves. 

 Inflorescence a dense narrow bipinnate panicle above 2 ft. long, 

 with a stout finely pubescent rachis ; many upper branches simple, 

 not exceeding 1-1^ in. ; a few of the lowest compound ; flowers 

 laxly disposed; flower-bracts minute, lanceolate, not rigid. Sepals 

 ovate, connivent, coriaceous, distinctly cuspidate, £ in. long, con- 

 nate above the very small naked trigonous ovary. Petals minute. 

 — Rio Dolce, dept. Livingstone, little above sea-level, Donnell- Smith 

 1825 ! A very distinct species, that comes in between mexicana 

 and Skinneri. 



M. (Platy^chmea) squarrosa, n. sp. — Leaves thin, ensiform 

 from a very large oblong base, altogether 2£-3 ft. long. H in.
