THE PALMS 
In commenting on the flowering of the palms I remarked last year 
that they had bloomed again here in cultivation, but did not set much fruit. 
The same trees have bloomed copiously again this year, in fact better than 
in 1928, and they will set fruit copiously again. But the past history of 
the palms is that they seldom fruit, as shown by the old peduncles still 
hanging on the trunks. The continued fruiting lately is certainly due to the 
unusual rains we have had. Yucca Whipplei bloomed again this year 
almost as copiously as before, but Mobavensis hardly bloomed at all, because 
of its remarkable blooming last yea 
gave Utahensis var. ‘as n. var. Plants with the general habit of 
Utahensis and about ten feet high. Leaves subulate from a broad base and 
about 6 inches long, tapering into a stout spine an inch long, with margins 
black base. Cross-section of leaves flatly triquetrous, leaves arcuate inward. 
Many peduncles several feet long, and ending in a very loose panicle with 
racemose rays rather distant as in ep eord and with flowers congested at 
the ends of the rays, and yellow, and not in an uninterrupted spike as in 
typical Utahensis, tube of perianth 1-2 lines long, and flowers not an inch 
long. Fruit not seen. Near the top of the divide above Oatman, Arizona, 
and along with Nolina Bigelovii.

Nolina Bigelovii (Torr.) Watson. The type locality; of this species is 
Bill Williams river, western Arizona, which stream flows just south of the 
i is Mt i j atman. found 
slopes in rocky places and continuing nearly to the foot of the range, Tropical 
life zone. The plant grows mostly in clumps though occasionally single 
stalks occur. They seldom have much of a trunk. The leaves are clustered 
in a fascicle at the top where the erect peduncle arises. The leaves are 
about 3 feet long and flat and not rough on the margins, an inch wide, and 
taper to a rather spinose tip, and the peduncle carries the magnificent panicle 
clear of the leaves, the panicle being much longer than the proper peduncle, 
and a compact lanceolate mass several feet long and tapering upward. The 
flowers are white, in a dense and spike-like raceme, 4-6 inches long, which is 
ascending and arises from the 1-2 foot long rays of the panicle. The 
flowers themselves are about 2mm. high and! 4 mm. wide, with segments 
2-3mm. long and oval-cup-shaped, acutish, very hyaline but with strong
